Abstract:
A method of welding surface-treated members together using a welding wire includes a step of transferring a droplet detached from the wire to the members; and a step of pushing the melt pool in the direction opposite to the direction of welding in such a manner that the gas generated from the members during welding is released from the site of generation. The melt pool is pushed to expose the overlapped region of these members. The gas generated from the members is released to the exposed portion, preventing generation of pores such as blowholes, and also generation of spatters.
