INDUCTION-BUTT WELDING OF VARIOUS-CONFIGURATION CHANNELS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to welding of various configuration channels and can be used for butt welding of pipes, rails of overlap welding of bands. Blanks surfaces are heated and contracted at preset force. Heating to required depth is performed by butt inductor. The latter is composed of a flat inductor shaped to profile of surfaces to be welded together. But inductor is arranged between welding surfaces to heat solely the surfaces to be involved in making of the weld. Inductor is removed from welding area before contraction of said surfaces.EFFECT: higher quality of the weld and power efficiency of welding.3 dwg
