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.
