<p>This Mechanical Drawing is Details of Grind a seam flat. Seam welding is <strong>the joining of work pieces made of similar or dissimilar materials along a continuous seam</strong>. Seam welding can be broken down into two main techniques, resistance seam welding and friction seam welding. Purpose of grinding is, Grinding is used <strong>to finish workpieces that must show high surface quality and high accuracy of shape and dimension</strong>. It has some roughing applications in which grinding removes high volumes of metal very rapidly. Spot, seam and projection welding Spot, seam and projection welding are <strong>carried out by electric resistance heating two overlapping metal parts which are pressed together by copper or copper alloy electrodes</strong>. Local melting occurs at the faying surfaces and an internal weld nugget is formed. For more details and information download the drawing file.</p>
