I would like to ask whether carbon dioxide welding can be used to weld the cracks in the rear axle housing of the cart. Carbon dioxide welding can be used to weld the cracks in the rear axle housing of large vehicles. Carbon dioxide gas shielded welding has high efficiency and good quality, and is widely used in automobile production. When the shell of the rear axle of the cart is cracked, carbon dioxide welding saves time and effort and has a good effect. Therefore, carbon dioxide welding can be used to weld cracks on the rear axle housing of trolleys.
