AI Technical Summary
During the rotary welding process of a rotating body, the protective gas output pipe cannot rotate synchronously with the rotating welding head, resulting in unstable gas delivery.
A mobile gas protection device was designed, which adopts a combination structure of universal wheel base, column, rotary joint and quick-connect joint to ensure that the gas output pipe rotates synchronously with the welding head and is connected to the gas guide chamber through the rotary joint to achieve stable gas delivery.
During the rotary welding process of the rotating body, the shielding gas can be continuously and stably delivered to the welding area, avoiding the twisting and tangling of the output pipe, and improving the smoothness and efficiency of the welding.
