Abstract
PURPOSE: To prevent the inclusion of nitrogen from air in arc manual welding by mounting a shielding box of specific inside volume to the parts to be welded, feeding an inert gas therein and welding said parts.
CONSTITUTION: A shielding box 6 of 450W15,000cm3 inside volume is mounted to materials 1 to be welded in the positions where a long hole 7 and a groove part 2 align. Next, an inert gas or CO2 alone or a gaseous mixture G thereof is fed into the box to expell the air in the box thoroughly, following to which the gas G is fed therein and while maintaining the air expulsion state, the parts to be welded are welded. Thereby, the content of nitrogen in weld metal is kept at a low level, and the stable weld zone of high toughness is obtained.
