TIG welding vs MIG Welding: What Is The Difference?

noreply@blogger.com (simple mechanism) — Tue, 01 Feb 2022 05:55:00 +0000

There exist a plethora of ways to go about welding now. There are many different kinds of welding in the modern world, with each of them having its own set of pros and cons. For this blog article, let’s focus on two popular ways of welding: TIG and MIG welding. To get started, let’s briefly discuss the two.

MIG Welding

MIG welding is Metal Inert Gas welding, which is also commonly known as GMAW or Gas Metal Arc Welding. Technological advancements in the time of war are a common narrative throughout history. The MIG welding process is one of those and was developed during World War II as a means to create weapons, etc. in a quicker and more efficient fashion.

The MIG welding process uses an arc of electricity that produces heat in the MIG wire as well as produces a non-reactive gas. With that, the metal melts and thus, successfully finishes the weld. This can be done by the MIG welder semi-automatically and automatically - the welder just needs to guide the electrode.

TIG Welding

TIG welding stands for Tungsten Inert Gas welding. TIG welding has a different procedure as opposed to the MIG welding process, of course. TIG welding uses non-consumable tungsten electrodes which then produce an electric arc for the final weld. This process does not need any additional metal and it can be performed manually or automatically. The electricity is passed through the metal tip of the electrode.

What are the different uses?

The common misconception of their interchangeability arises from the term ‘inert gas’ being present in both. However, MIG welding and TIG welding are not just different processes, but the kind of implementation and usage they have are also different and varied.

TIG welding is ideal for smaller-scale projects like welding a lawn mower, a bicycle frame, etc. It works well on metals like nickel, brass, gold, and alloys of these metals. MIG welding, as opposed to this, works well for projects on a larger scale. This includes welding requirements for motor vehicles as well as bodywork on them. This difference exists as TIG welding is a slower process that requires more patience and it pays more attention to the details and intricacies of the welding process. And because the MIG welding process has a continuous feed, it is faster. MIG welding is considered to be simpler and easier to master than TIG welding due to the same detail.

What are the different benefits?
Both types have their own lists of pros and cons. By now we have learned two of these already,

The MIG welding process requires a MIG wire, whereas TIG welding does not require an additional metal.
TIG welding is more apt for smaller sections whereas MIG welding is commonly used on bigger surfaces.

Here are a few more pointers of the varied pros and cons for both types:

● MIG welding can be used on a variety of metals from thin to medium and thick metals.

● TIG welding creates more accurate and cleaner welds as opposed to MIG welding.

● TIG welding does not produce any sparks and splatter.

With all of this said, the choice of the kind of welding for a project is entirely contextual. It depends on the scale of the project, the metals that are in play as well as the budget! We hope this article has helped you in understanding MIG and TIG welding better!

Smithy Shop

Smithy or Forging is the oldest shaping process used for producing small articles for which accuracy in size is not so important. The parts are shaped by heating them in an open fire or hearth by the blacksmith and shaping them through applying compressive forces using a hammer.
In another Words:-The process of giving the desired shape of a metal piece by heating and hammering is also known as forging. The metal is heated up to a Desire temperature known as a forging temperature. When the forging is done by hand tool manually then it is called hand forging and when the same forging is performed by the power hammering then it is called power forging.

Foundry Shop

The place where a job or work is prepared by melting and pouring the molten metal into the mold is known as Foundry. In this process, a mold is prepared with sand or any metal. If mold is prepared by sand, is known as sand molding.
This sand is prepared to add the sand content and riddled properly. After this with the help of a pattern make a mold. The mold is a cavity of any desired shape which is required. The pattern is placed in the flask and rammed properly. After completion of the mold, the molten material is prepared by heat. The solid material is placed in a furnace by means of the crucible. When the material becomes liquid then pour it into the mold with the help of a pouring ladle and crucible handle. After cooling the product or job is prepared. The process described above is called Casting.

Molding and Casting

noreply@blogger.com (simple mechanism) — Sat, 04 Jan 2020 11:52:00 +0000

Hello, friends, I will show you how to do casting easily.

The casting is the quickest way to produce a complicated shape. The casting is the mechanism that produces a new shape that you want. Let us start the casting from starting. First of all, we are produce a mold with the help of sand. The mold is a cavity that is created by some particular patterns. The cavity that is produced in the sand is called mold.

In a simple way, if we talk about casting, the casting is completed in two parts.

1 To make a mold.

2. To pouring the molten metal into the mold.

So we are going to start the 1st process.

Molding

First of all, we collect the sand which is required. So when we are making a mold we required Silica sand, Clay, and some moisture. When we go to technically we follow all the rules. I mean for molding purposes we use some tools. The tools details are given below.

If you learn about casting you must know about the tools. And I also mention that all work that is covered in this topic comes under the foundry shop. If you learn more about the foundry shop you can click here.

In this link, I also explain some other topics which are related to the Foundry shop.

So the details of the tools are.

1. Flask

2. Showel

3. Trowel

4. Lifter

5. Hand Riddle

6. Strike of Bar

7. Vent Wire

8. Draw spike

9. Rammer

10. Slicks

11. Smoother

12. Sprue Cutter

13. Bellow

Let's start to make a mold.

First of all, set the flask on the floor. Set the lower part whose name is a drag . If we are talking about the sand mold we also knowledge about sand. For sand casting, we use green sand but the sand used for casting available in many types. If you want please visit the Foundry shop. So we work with only green sand. The green sand is natural sand. In this case, we produce green sand. We collect Silica sand. The silica sand is the content of sand. It means in single sand has different content of sand. So we collect only silica sand. How to understand about silica sand. Simply the silica sand is the water-absorbing sand, which means the sand is dry in condition and brown in color. So if we work with green sand we collect silica sand and then clay. After completing the two content we mix properly the sand. We mix with hands. Ater mix the sand properly we add moisture. In green sand, we use the molasses. The molasses is a binder which increases the strength of green sand. When we complete all the processes then next we place the pattern in the drag part. The pattern is the same copy of our product which we want to produce. But some allowance is provided in the pattern. After placing the pattern in the drag part put the green sand and fill all sides of the pattern. The pattern that is used for molding is split. So we can use easily in two parts. The 1st part is used for the drag and the second part is used to cope. Fill the drag part completely and rammed it with the help of the Rammer tool. After complete ramming removes the excess sand from the outer face of the drag part. The removal of this sand we can use the tool which name is Strike off bar. Then next sprinkle the parting sand. I also remind that this post is only about the molding and casting process if you can learn about sand and their type or any other information about the foundry shop please visit our official website Simplemechanism After sprinkling the parting sand we place the second part that copes part. Similarly, place the remaining part of the pattern as same as a mirror. Then next fill with sand and also rammed it properly. After rammed remove the excess sand by Strike of Bar. Our molding process is almost complete. Now we provide some vent for proper ventilation. We provide two-hole

1st is Runner

2nd Riser.

This is important for the exam point of view. The runner is provided for pouring the molten metal into the mold. On the top of the runner provide the pouring basin. The second hole Riser is used for removing the gases which are producing during the casting. The molding is done.

The 2^nd is pouring the molten metal into the mold.

I mention that the whole casting is done in two parts. So we complete the 1st part that includes the tools and molding. The second part is to pouring the molten metal into the mold. The second part is done on the furnace. In my case, this is not my case in engineering college basically in the workshop we use an open-heart furnace. The furnace is used to produce the heat. The furnace we can use according to the requirements. If you can use solid fuel that we use coal furnace and if we use liquid that called oil furnace. And if use gas furnace so it called the Gas furnace.

We use a coal furnace. So the furnace name is open heath furnace. So for producing heat, we can use

coal.

The coal is three types

1. Wooden coal

2. Steam coal

3. Charcoal

We add some woods part or you can use wooden scraps for easy burn the fire. If the fire starts to burn we add some wooden coal. When wooden coal start burns then next we add steam coal and charcoal but remember before placing the coal in the furnace's hearth, place the crucible. The crucible has a solid piece of your products for example if you are doing casting and make a spanner of aluminum. So you add a solid part of aluminum in the crucible. Place the crucible on the coal and center in the hearth. Before this, you must complete the brick lining around the hearth. The main function of the brick lining is to prevent heat transfer. If you are performing aluminum casting the material will melt within 35 to 45 minutes. You can check the material by poker tool. The poker tool is a simple wire that is bent at the end. If your material converts into the liquid you can pour this material into the mold. After completion, the pouring the finishing will remain. At this position your casting almost complete.

If you understand about this basic mechanism please comment below and any other questions or suggestions, please comment to me.

Thanks

Pattern allowance in hindi

noreply@blogger.com (simple mechanism) — Sat, 23 Nov 2019 12:15:00 +0000

Pattern shrinkage allowance

पिघला हुआ धातु को मोल्ड में डालने के बाद, धातु में जमने के दौरान सिकुड़ने की प्रवृत्ति होती है। कुल कास्टिंग उत्पाद सिकुड़ जाता है और पैटर्न से छोटा हो जाता है।पैटर्न और कास्टिंग के बीच मै अंतर होने के कारण उसे shrinkage allowance के रूप में जाना जाता है। धातु को डालने के दौरान संकोचन को प्रभावित करने वाला कारक तापमान होता है

Machining allowance for sand casting

कास्टिंग करंने के लिये machining allowance की आवश्यकता होती है।मशीन अलाउंस बनाने के लिए पहले ड्राइंग की जाती है. जिस स्थान पर मशीन अलाउंस करनी होती है ओस पर अलग से लीनिंग की जाती है जिससे shrinkage अलाउंस को अलग रखा जाए

Draft allowance

Draft allowance में, पैटर्न सभी vertical सतहों से टेंपर्ड रहता है। यह आंतरिक और बाहरी सतहों को प्रदान करता है। पैटर्न को आसानी से हटाने के लिए यह आवश्यक है। यह ऊर्ध्वाधर ऊंचाई और मोल्डिंग विधि पर निर्भर करता है।

Shake allowance

सभी की पैटर्न मुट्ठी को वापस लेने से पहले, इसे हिलाया जाता है ताकि यह आस-पास की दीवार से मुक्त हो जाए, क्योंकि मोल्ड गुहा के इस आकार में वृद्धि के कारण पैटर्न को नकारात्मक allowance दिया जाता है।

Distortion allowance

कुछ निस्चित कास्टिंग होती है जो टूट जाती है इस के कारण इस को डिस्टॉरशन कहते है कूलिंग मैं अंतर होने के कारण जे डिफेक्ट हो सकता है

Movement of mould wall

Drawing Process

Drawing is the process in which a red hot metal piece is beaten up by a hammer and the thickness of diameter is decreased but length increased. The hammering is done by placing the hot pieces on the anvil ﬁrst, the road is subjected to a plastic stage in the Furnace up to the desired length. The piece is kept on the horn of the anvil or on the bottom part of following by hammering with the help of the hammer. When the shape is round then it is converted into square-shaped by the face of the hammer and length is increased then it is converted into an octagon shape and do the hammering regularly till the desired shape is achieved.

Upsetting

It is the process in which the diameter of the hot workpiece is increased and length is reduced. The hot metal piece is placed on the Anvil in a vertical position. It is struck with the hand hammer the hot workpiece is held in a long time. During upsetting bending occur on the job in such cases ﬁrst the job should be straight and then upsetting should be continued.

Punching Process

Punching is the process in which a hole is made into the hot work piece. The job is heated to the desired temperature and then it is placed on the hot metal piece with the help of sledgehammer. The hammer is forced to piece the battle to half the metal thickness then the punching is done.

Drifting

It is a process of ﬁnishing and enlarging the hole. The process is similar to punching. To continuous punching without using a die is called drifting but the tool is used is known as Drift.

Swaging

The swaging is a process of ﬁnish different shapes such a circular hexagonal and square. The workpiece is held in two part of the swages and after holding the piece the hammering is done with the help of a hammer.

Fullering

The fullering process is done on an anvil. The lower part of the fuller set is kept in the whole of the anvil. The hot workpiece is placed in the groove on the lower fuller. The hammering is done on the upper portion of fuller and workpiece is placed on the fuller. The fullering is done for drawing and growing process.

Bending

Bending is a process which is commonly used for the forging process. It is simplest method of bending a piece of metal in hand forging is to support it on the anvil. and hammering on it When it is bent, the metal of the workpiece thins out round bend causing weakness.

Forging Welding

The Forge welding the process of joining two metal pieces by heating and hammering is known as Forge welding. The metal pieces are to be welded are cleaned and heated in a furnace up to the welding temperature then both pieces are heated up to the desired temperature and picked from the Furnace with the help of tongue. The workpieces are placed on each other and hammering is done on them and both the pieces get a weld.

जिस स्थान पर काम पिघला हुआ धातु पिघलाने और मोल्ड में डालने से तैयार किया जाता है, उसे फाउंड्री के रूप में जाना जाता है।इस प्रक्रिया में, रेत या किसी धातु द्वारा एक सांचा तैयार किया जाता है।यदि रेत द्वारा तैयार किया जाता है, तो Sand मोल्डिंग के रूप में जाना जाता है मोल्डिंग के लिए उपयोग की जाने वाली रेत है:

Green sand

Dry Sand

Loam Sand

Facing Sand

Parting Sand

यह रेत रेत के सामग्री को जोड़ने के लिए तैयार किया जाता है.इसके बाद पैटर्न की मदद से एक सांचा बनाएं। मोल्ड किसी भी वांछित आकार का हो सकता है। पैटर्न फ्लास्क(Flask ) में रखा गया है और उचित घुसाया गया है। मोल्ड पूरा होने के बाद पिघला हुआ पदार्थ(Molten Metal ) गर्मी से तैयार किया जाता है। ठोस पदार्थ को एक Crusible के माध्यम से भट्ठी में रखा जाता है। जब सामग्री तरल हो जाती है तो क्रूसिबल हैंडल की मदद से इसे मोल्ड में डालना होता है। उत्पाद को ठंडा करने के बाद एक piece तैयार किया जाता है। ऊपर वर्णित प्रक्रिया को कास्टिंग कहा जाता है।

Green Sand

मोल्ड green sand की रेत से तैयार किया जाता है और डालने का कार्य रेत में रेत के साथ किया जाता है और इसकी हरी या प्राकृतिक अवस्था को ग्रीन सैंड मोल्डिंग के रूप में जाना जाता है। हरी रेत के उत्पादन के लिए मिश्रण तैयार किया जाता है, जिसमें सिलिका रेत (Silica Sand) होती है। हरी रेत का निम्न अनुपात।

1. Clay 10 से 15%

2. नमी 4 से 6%

Clay और नमी की सामग्री se इसे मिलाया jata hai। पूरा होने के बाद, रेत का मिश्रण फ्लास्क ड्रैग (drag the bottom part of flask)भाग को खोलने के लिए लकड़ी के बोर्ड को फर्श पर रखता है। Flask को लकड़ी के बोर्ड पर रखें। लकड़ी का बोर्ड अनिवार्य नहीं है यह वैकल्पिक है। इसके बाद, पैटर्न को खींचकर रखा जाता है और अगर पैटर्न एकल हो तो सामना करना पड़ता है। यदि पैटर्न को विभाजित किया जाता है, तो पैटर्न के ड्रैग पार्ट को पहले रखें और स्ट्राइक ऑफ बार की मदद से अलग किया गया। रेत ठीक से घुसा हुआ है और बॉक्स पलट गया। पैटर्न का दूसरा भाग स्थिति में रखा जाता है जिसके बाद सामना किया जाता है। रनर और रिज़र को स्थिति में रखा जाता है और बॉक्स को रेत से भर दिया जाता है और ठीक से घुसाया जाता है। रनर पर, इसमें सामग्री डालने के लिए चिकनी डालने के लिए बेसिन डालना। वेंट तार का उपयोग वेंट प्रदान करने के लिए किया जाता है। पैटर्न को हटाने के बाद बक्से को इकट्ठा किया जाता है। सांचे को तैयार किया जाता है।

Dry Sand

यह प्रक्रिया रेत की संरचना की अपेक्षा करने के लिए ग्रीन्सैंड मोल्ड के समान है। रचना हरी रेत से अलग है। सूखी रेत तैयार करने के लिए विशेष प्रकार के बांधने की मशीन का उपयोग किया जाता है जैसे कि राल, मिट्टी या गुड़। इसका उपयोग एक मजबूत बंधन बनाने के लिए किया जाता है। यहां फिर से वही प्रक्रिया दोहराई जाती है। पूरा होने के बाद, सूखी रेत का मिश्रण, ड्रैग रखें और पैटर्न डालें। उसी तरह जब लकड़ी के बोर्ड की आवश्यकता होती है यदि फर्श चिकना नहीं है तो सूअर का उपयोग करें यदि नहीं, तो यह अनिवार्य नहीं है यह वैकल्पिक है। इसके बाद, पैटर्न को ड्रैग और सामना के बीच रखा गया। यदि पैटर्न को विभाजित किया जाता है, तो पैटर्न के ड्रैग पार्ट को पहले रखें और अतिरिक्त सैंड को स्ट्राइक ऑफ बार की मदद से हटा दिया जाता है। रेत ठीक से घुसा हुआ है और बॉक्स पलट गया। पैटर्न का दूसरा भाग स्थिति में रखा जाता है जिसके बाद सामना किया जाता है। रनर और रिज़र को स्थिति में रखा जाता है और बॉक्स को रेत से भर दिया जाता है और ठीक से घुसाया जाता है। यहां एक ही मोल्डिंग बॉक्स को ओवन या स्टोव के साथ टेम्पर्ड किया गया है। गर्मी की मदद से रेत में सभी नमी को हटा दें। सूखी रेत का सांचा तैयार किया जाता है।

Loam Sand

लोम रेत की प्रक्रिया ऊपर वर्णित उन दो से पूरी तरह से अलग है। सबसे पहले, ईंट और दोमट रेत का उपयोग करके हाथ से संरचना तैयार की जाती है। स्टिक और स्वीप के माध्यम से वांछित आकार बनाने के लिए दोमट रेत और ईंटों द्वारा किया जाता है यह एक पैटर्न रहित प्रक्रिया है। पैटर्न के अभाव में भी यही प्रक्रिया की जाती है। मोल्ड के पूरा होने के बाद, इसे ताकत देने के लिए बेक किया जाता है। इसमें मोल्ड बनाने के लिए दोमट रेत और मिट्टी का अतीत तैयार किया जाता है।

Facing Sand

इसे मोटी रेत कहते हैं। Facing रेत का मतलब पैटर्न के चारों ओर इस प्रकार की रेत है। यह fresh और अच्छी तरह से टेम्पर्ड रेत है। रेत का सामना करके दिए गए पैटर्न की सतह के आसपास प्रारंभिक कोटिंग कि जाती

Parting Sand

पार्टिंग सैंड जिसे नाम दिया गया है, इसका उपयोग दो हिस्सों के बीच और सुरक्षित हटाने के लिए पैटर्न के आसपास किया जाता है। दो भागों का मतलब होता है Cope and Drag।जली हुई रेत और सूखी सिलिका रेत का इस्तेमाल जुदाई रेत के रूप में किया जा सकता है।

Hammer

noreply@blogger.com (simple mechanism) — Wed, 03 Apr 2019 16:37:00 +0000

The striking tools are used in different shops for different operations. The striking tool is identified by a hammer. These hammers are used for chipping, fitting and punching processes. A hammer has a heavy iron body with a wooden handle. The weight range from 0.25 kg to 2 kg. The hammer is many types but the classification of the hammer can be done by their shapes of pean. The pean is the top part of the hammer. When the pean shape changed the name of the hammer also changed.

Straight Pean Hammer

If the shape of the pean is parallel to the handle of the hammer is called straight pean hammer.

Ball pean hammer

The shape of the pean is like a ball or spherical is called a ball pean hammer.

Cross pean hammer

If the pean across the handle then it is called cross pean hammer. It has a cast steel body. This type of hammer is used for wooden work and metallic work.

Double-ended hammer

If the shape of the pean is the same as face it is called a double-ended hammer.

Claw Hammer

The claw hammer is used for striking and pulling the nails from the wooden piece. The one end is made for striking and second claw face. The weight varies from 0.25 kg to 0.75 kg.

Mallet

It is made up of hardwood and round or rectangular in shape. It is used to strike the chisels which are wooden handles.

Hand Hammers

Hand hammer is a light in weight used by Smith himself. Sledgehammer is heavier in weight and is used by the Smiths helper. All the hammers are divided into 4 parts namely

Cold Chisel

noreply@blogger.com (simple mechanism) — Tue, 02 Apr 2019 16:39:00 +0000

This is also a cutting tool that is used on the workpiece as a cold or hot condition. These are made up of high carbon steel. It is generally 6 inches to 8 inches long. The top is flattened and sharp cutting edge made on the bottom side. Chisels are classified on the basis of the shape and width of the cutting edge. Commonly used forms of chisel are flat, cross-cut, half-round and diamond point chisel.

Cutting angle of chisels

For hard material 70-75 degree

For medium-hard material 60 degree

For soft material 40 degree

Flat Chisel

This chisel is flat in shape at the end side. The flat chisel is used for chipping a large surface. This chisel is used at room temperature so it is called a cold chisel.

Crosscut chisel

The crosscut chisel is narrow chisel and thickness of the cutting edge is broader than a flat chisel. The flat chisel is used for cutting grooves.

Half-round chisel

The half-round chisel is used to cut oil grooves in the bushes and also clearing small round corners.

Diamond point chisel

The diamond point chisel is used for chipping plate. It is also used for clearing the corner of the slots cut at an angle or of a square shape.

Chipping with chisel

The workpiece is proper to hold in the vice. The material is removed with the help of a hammer. The chisel has held an angle to the workpiece. The chisel is perfectly held in the hand while striking.

Flat file

noreply@blogger.com (simple mechanism) — Mon, 01 Apr 2019 17:04:00 +0000

Files

A file is a tool which has multi-tooth. It is used for remove the unwanted material by means the rubbing on the metal. The files are available in many shapes and size.

Classification of the file according to shape, size and the degree of coarseness.

Rough
Bastard file
Second cut
Smoothe
Dead smooth

The rough file and bastard file are the big cut files. Where material is more the rough file is used. These files have bigger teeth.

Dead smooth file smooth have smaller teeth and used for finishing work. The second cut file has the degree of finish midway between bastard and smooth file.

Classification on the basis of shape and size

The files are available in many shapes and size. The length of the file varies from 4 inches to 14 inches. The shapes available are square, round, triangular, half round, etc.

Number of cuts

According to the cuts, the file are two types

Single cut

In the single cut file, the teeth of the file are cut in parallel rows at 60 degrees to the face.

Double cut

In the double cut file, the teeth of the file are cut in parallel rows and the opposite direction at 60-degree angle.

Pitch

The number of teeth in one centimeter is called pitch of the file. The number of teeth varies from 10 to 40 in one centimeter.

Use of file

The file is held in perfect and horizontal in position. Most of the files have their teeth pointing forward. So the pressure should be applied in forward stroke. The work is held in a vice after marking. Keep the right hand on the handle and left hand of the left end. The file movement (Forward and backward )speed of 15 to 25 stroke per minute. The rough file is used where material removing is the more and fine file is for finishing work.

Care of file

The teeth should be protected from excessive wearing.
The file should be stored in wooden rake.
Clean the file after use by the file cleaner.
The file should be coated with oil when not in use.
