Abstract
When sheet metal parts are assembled by spot welding, small pips are raised on the surface of one of the parts by forming dimples on the opposite surface. The wellded assembly is placed in a press so that the pips are deformed and the surfaces of the welded parts come into direct contact with each other. The process is particularly applicable to the manufacture ofathe wedge plates for a sluice valves.
