Abstract
In the bonding of an aluminum alloy material () to a steel material () by TIG welding, a tungsten electrode () which has a tip having a diagonally cut tip face () and asymmetrical to the electrode center axis () is used. The tungsten electrode () is oriented toward the welding line from the upper side of the aluminum alloy material () in such a manner that the tip face side of the tungsten electrode () faces the aluminum alloy material () side and the tip () of the tip face () faces the steel material () side. In this manner, an arc () from the tip () is directed to the steel material () side.
