LONGITUDINAL WELDING JIG FOR MOTOR FRAME MAIN BODY

摘要

The longitudinal seam welding apparatus is for welding a longitudinal joint of a cylindrical main body of an electric motor frame. A rigid tabular welding jig includes a guide for engaging the joint of the frame main body to be welded for longitudinally guiding the frame main body. A pusher passes the main frame body through the welding jig. A welding torch seam welds the joint of the frame main body. A welding jig comprises a rigid tube having a bore with a diameter in which the frame main body can be snugly and slidably inserted.
