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