Abstract
The invention is a welding tool used in a friction-stir welding apparatus for welding a plurality of members to be welded. The welding tool includes: a tool holder having a front end and a base end, the base end being held by the friction-stir welding apparatus so as to be driven to rotate and move by the friction-stir welding apparatus; and a welding unit of a wear resistant material adapted to be removably mounted on the front end of the tool holder, the welding unit mounted on the front end of the tool holder being immersed into a part of the members to be welded during a friction-stir welding.
