-0- AUTOMATIC SPEED CONTROL FOR SEAM WELDING ABSTRACT OF THE DISCLOSURE A welding machine for use in connection with seam welding a pair of metal parts which are positioned to form a welding groove, and wherein the groove width undesirably varies at random due to improper part positioning or devia- tions from desired tolerance. The weld head is moved along the groove by a drive motor and is preceeded by a pair of fixedly connected sensing probes. The primary probe follows the groove wall portion of one of the parts, while an aux- iliary probe follows a surface on the other part. Varia- tions in groove width cause variations in the distance be- tween the two probe tips, said latter variations being utilized to automatically change the speed of the weld head drive motor. -0-
