					<description><![CDATA[Resistive spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. The process uses two shaped copper alloy electrodes to concentrate welding current into a small &#8220;spot&#8221; and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt [&#8230;]<div class='yarpp yarpp-related yarpp-related-rss yarpp-template-list'>
