Abstract
Provided is a consumable electrode type arc welding method and device in which stable welding can be performed at a high speed for a welding gap greater than a thickness of a base metal and the like, and welding conditions are automatically changed according to the welding gap along a welding line to perform the stable welding. A first base metal extended vertically and a second base metal which has an upper end positioned in a middle portion of the first base metal and is provided along the first base metal are welded together. The first and second base metals have a thickness of 2.8 mm, and an arc is generated toward an upper end portion of the second base metal from obliquely above on a side opposite to the first base metal. The second base metal is melted to be a part of a weld metal. An amount of the second base metal to be melted is increased or decreased according to a welding gap detected by a laser sensor.
