Abstract

PURPOSE: To carry out arc welding of high tension steel not preheating or preheating at less than 50°C without producing weld crack, by carrying out gas shielded arc welding using filler metal having lower yield point and tensile strength than basic material.
CONSTITUTION: Arc welding is carried out by shielding with CO2 using the material having yield point of 80W100% of that of basic material and lower tensile strength than the basic material at 30W45° of groove angle, on occasion of carrying out arc welding of 50kg/mm2 or 60kg/mm2 class high tension steel. By the above method, weld crack is able to relieve without lowering mechanical strength by carrying out not preheating or preheating at less than 50°C.
