Abstract

This invention discloses a special welding equipment for automotive insulation connecting pipes, belonging to the field of specialized welding technology. It includes a main frame and a positioning mechanism for vertically positioning the insulation pipe end and flange during welding. The main frame is equipped with a clamping mechanism for feeding and clamping the insulation pipe end and flange to be welded, and two welding mechanisms for welding the insulation pipe end and flange. The invention features side-sealed doors on both sides of the welding box, with automatic opening and closing achieved through a linkage mechanism between a movable seat and an inward-opening door frame. When the welding torch enters the welding station, the side-sealed doors automatically close, isolating the welding area from the external environment, effectively reducing spatter, fumes, and arc light leakage, improving operational safety, and preventing external airflow from interfering with the weld pool, ensuring weld quality. After welding is completed, the side-sealed doors automatically open as the movable seat retracts, achieving fully automated control of the entire process.
