Welding method provides for relaxation of residual mechanical stresses

摘要

FIELD: procedures for joining parts by welding due to surfacing additive metal.;SUBSTANCE: method for joining parts by welding comprises steps of performing first pass for surfacing part joining layer and at least second pass for surfacing joint filling layer; just before second pass flush-cutting thickened portion formed at back side of joining layer and extending outside joined parts. It provides possibility for limiting plastic deformations in zone of welded seam promoting relaxation of inner mechanical stresses.;EFFECT: possibility for relaxing residual inner mechanical stresses.;2 cl, 4 dwg
