Abstract
Surfaces of metal workpieces being welded are fused at a constant speed of feeding the workpieces towards each other, and the speed of feeding is, before the upsetting, increased to a final value thereof for a period of (1.0 to 4.0) (.DELTA.max/v.sub.1), where .DELTA..sub.max is the maximum gap between the workpiece surfaces being welded and v.sub.1 is the average speed of feeding the workpieces over the period of its increase. Empirical formulas are given to determine the maximum gap for workpieces of various thicknesses.
