A motor-driven welding machine capable of holding and carrying a welding torch stably along a welding line, the machine including adjusting means for varying the mounting position of a welding torch or the inter-axle distance of carriage wheels according to the type of the welding torch to be held thereon. The machine further includes means for allowing or stopping oscillatory or pivotal movements of the welding torch in horizontal and vertical planes and means for steering the carriage wheels in relation with the oscillatory movements of the torch.

Motor-driven welding machine

The present disclosure relates to an overhead submerged arc welding process wherein a flux for the submerged arc welding is supplied from the underside of the welding line while at the same time a consumable electrode is supplied from the underside of the welding line, the process being characterized by maintaining the interrelationship between a flux supply cylinder and the plates to be welded such that the length from the under surfaces of the plates to be welded to the upper end of the open flux supply cylinder and the diameter D of the opening at the end of the flux supply cylinder is represented by the formula 2.ltoreq.D/I.ltoreq.15.
