Abstract
The welding method comprises: a step of preparing a first base material and a second base material; a step of disposing the first base material and the second base material in a manner such that a first end face of the first base material and a second end face of the second base material face each other; and a step of welding the first base material and the second base material together using GMA welding so that the first end face and the second end face are joined together. In the step of welding the first base material and the second base material together, an arc is formed in a state where the welding wire penetrates into a region surrounded by a molten region, so that the molten region is formed to pierce through the first base material and the second base material in the thickness direction.
