FIELD: technological processes.
SUBSTANCE: invention may be used to make welded products of box-like shape with corrugated walls, in particular transformer vessels. Sections of corrugated wall are welded to product body by means of overlapping seam, as well as corrugation bases to produce seams with periodical variable cross section. Welding speed is measured by commands from welding burner position detector with account of measurement of distance it traveled proportionally to ratio of fused seams cross section areas. When welding burner reaches corrugation base, welding speed is reduced, and after corrugation base has been welded - it is increased.
EFFECT: invention provides for higher quality of welded seam and increased efficiency with reduction of production expenses.
