Abstract
A method for performing arc welding includes steps of: preparing two work pieces each having fused portion, being butted against one another; preparing a welding electrode which is a non-consumable type electrode used for performing arc welding to the two work pieces, the welding electrode being disposed to face the two work pieces; applying welding current to the welding electrode so as to have the two work pieces welded; and performing a current changing step to change an amount of the welding current to be decreased so as to have a fused portion of at least one of the two work pieces move toward the other work piece for adhesion to the fused portion of the other work piece or for adhesion to the other work piece itself.
