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.

A welding tool used in a friction-stir welding apparatus for welding a plurality of members to be welded, comprising:
- a tool holder having a front end and a base end, said base end being held by said friction-stir welding apparatus so as to be driven to rotate and move by said friction-stir welding apparatus;
- a welding unit of a wear resistant material including a mounting section that is removably inserted in said front end of said tool holder, said welding unit removably inserted in said front end of said tool holder being immersed into a part of said members to be welded during a friction-stir welding;
- and
- a fixing member adapted to be mounted on said tool holder for removably fixing said welding unit to said tool holder, said fixing member abutting said mounting section of said welding unit on a surface of said mounting section that is substantially parallel to a surface of a member to be welded.
A welding unit used for a welding tool,
- wherein said welding unit is made of a wear resistant material and inserted in said front end of said tool holder, said welding unit inserted in said front end of said tool holder being immersed into a part of said members to be welded during a friction-stir welding,
- wherein a fixing member adapted to be mounted on said tool holder for removably fixing said welding unit to said tool holder, said fixing member abutting said mounting section of said welding unit on a surface of said mounting section that is substantially parallel to a surface of a member to be welded.
