The supporting arm and lifting arm of the obstacle removal vehicle are all made of high-strength steel plates, which are formed by bending. Carbon dioxide automatic protective welding only allows two welds, with few welds, small deformation, high precision and strength, and ultrasonic weld detection. Carbon dioxide shielded welding and argon arc welding are adopted for the welding of the obstacle removal vehicle. The weld length is more than 300 mm. Automatic seam welding is adopted to make the weld surface smooth and beautiful.
