Abstract

PURPOSE: To weld medium thickness steel plates efficiently and economically by spraying a specific amt. of filler metal beforehand in the groove bottom part on backing pass side, specifying welding current and performing root pass welding by leaving an unmolten part in the groove bottom.
CONSTITUTION: Filler metal CW of ≥2.5g/10cm welding length is beforehand sprayed in the groove bottom part on BP (backing pass) side and welding current is set at ≤600A in butt welding of a joint of V, Y of X type of ≤45° angle of bevel. Root pass welding is carried out by leaving an unmolten part in the groove bottom, and this unmolten part is removed by the penetration of the root pass weld metal on FP (finishing pass) side or back chipping piror to welding on the FP side. Thereby, the occurrence of high temp. cracking or undercut is prevented, the removal of the unmolten part is made easy and welding is accomplished efficiently.
