Abstract

PURPOSE: To miniaturize the device and improve the welding efficiency, by providing a backing strip slidable to the groove end on the upper part of a backing device main body, and a guide groove seated on a rail running along the groove end in the lower part thereof, and disposing the driving wheels and other parts abutting against the rail in specified locations.
CONSTITUTION: A backing strip 7 slidable to the lower side of a groove end A of the base metals 11, 11 is provided repulsively on the upper side of a backing device main body 6, and a guide groove 2 to be seated on a tubular rail 1 suspended along the groove end A is fitted on the lower side thereof. Driving wheels 3, 3 and guide wheels 4, 4 respectively abutting against the top and right and left sides of said rail 1 are provided along the guide groove 2. And a parallel holding arm 23 having a roller 12 rotatable on the base metals 11, 11 fitted at its end is provided at both sides of the main body 6 to constitute the device. In this constitution, the device is miniaturized, and the device can easily run beneath through the scallop part, so that complicated curved plates may be welded efficiently.
