Abstract:
PURPOSE: To prevent the generation of high temp. cracking in the state of gas shielded arc welding of dead soft steel by using a composite wire contg. a specific content of C.
CONSTITUTION: In the case of subjecting steel contg. 0.005W0.06wt% C to gas shielded arc welding, at least the 1st layer thereof is welded by using a composite wire contg. 0.1W0.34wt% C.
