Abstract

PURPOSE: To prevent the degradation in corrosion resistance in weld heat affected zone in welding of austenitic stainless steel, by suppressing the deposition of Cr carbide in the weld heat affected zone by water cooling.
CONSTITUTION: Austenitic stainless steel 1 is welded by the weld metal 2 produced by the welding arc from a welding wire 3 to which welding current is led from a power supply tip 9, in a shielding gas 4 such as Ar or Ar+CO2. In this case, the double torches are used and the water flow of high velocities is discharged from 6 of the trumpetlike nozzles 5, 6 provided at their end, whereby the weld zone of high temperatures is quickly cooled. Further, a cavity forming gas is discharged from the nozzle 5 to the inner side of the abovementioned water flow to form a stable gas phase area. The weld zone is quickly cooled by the water jet of high velocities discharged from the nozzle 6, whereby the deposition of the Cr carbide which degrades corrosion resistance is prevented.
