METHOD OF PLASMA-ARC FACING OF SHAFTS AT CONSTANT WIDTH OF WELD BEAD

摘要

FIELD: welding and surfacing. SUBSTANCE: in proposed method of mechanized plasma-arc facing of shafts and other solids of revolution constant width of weld bead is maintained and, consequently, its shape by changing arc power according to program calculated with due account of temperature of workpiece in front of arc. EFFECT: enhanced quality.
