Filed: 1983-10-26
Abstract: PURPOSE:To form a weld bead into a wave shape, and to prevent the propagation of initial cracks to large cracks by responding the rotation of work to be welded and a welding torch holder. CONSTITUTION:The rotation of rotating work 1 to be welded are transduced to pulses by a rotary encoder 2, and the generated pulse signal is put into a motor 4 running in accordance with the number of the pulses, by which a welding torch holder 5 is moved.
