    Abstract: In high frequency welding apparatus in which high frequency electrical heating current is supplied to metal surfaces to be welded together by contacts engaging the metal which is advanced toward a weld point, the contacts engage the metal in advance of the weld point and have contact faces with downstream edges contacting the metal. The downstream edge of one of the contacts, or the downstream edges of the both of the contacts, is or are skewed with respect to the path or paths of the metal surfaces to be heated so that the downstream edge or edges extend at an acute angle of about 35.degree. to about 55 .degree. with respect to the path or paths of the metal surface or surfaces, the angle being intermediate the contacts and the weld point.

    Abstract: A welding robot has a gun main body, a stationary electrode tip which is immovable relative to the gun main body, and a movable electrode tip which is mounted on the gun main body and is opened and closed by a pressing source. The gun main body is movable by a driving source in a direction in which both the electrode tips lie opposite to each other. In teaching the welding robot by the movement thereof to each weld spot position of a workpiece, the movable electrode tip is moved in a closing direction relative to the gun main body by the pressing source in a state in which the gun main body is kept stationary at a predetermined position relative to the gun support bracket. The stationary electrode tip is moved in the closing direction by a relative movement of the gun main body relative to the movable electrode tip after the movable electrode tip has come into contact with the workpiece. A position at which the stationary electrode tip contacted the workpiece is detected. This position is stored as teaching data.
