The conducting nozzle is used for conducting current to the welding wire inserted in the conducting nozzle, and the nozzle is used for spraying protective gas. In the gas shielded welding process, welding spatter will quickly adhere to the outer surface of the conducting nozzle, the inner surface of the nozzle, the gas protection sleeve and the shunt device, and the protective gas flow flowing through the gas nozzle will be affected by the deposited welding slag, so that air can also reach the welding position, thereby affecting the protective gas flow, such as reducing the purity of the carbon dioxide protective gas flow, and further affecting the stability of the electric arc in the welding gun and the weld quality of the welded workpiece, and making the nozzle, shunt device and other devices more easily damaged. In addition, after a period of accumulation, the welding spatter can easily block the gas flow channel of the protective gas in the nozzle, thereby affecting the welding quality.

However, this method has the following defects: 1. A set of reamer device needs to be additionally provided to clean the welding gun, which occupies a large space, and if the robot welding gun is installed in a narrow working position, the reamer device is easy to interfere with the robot welding gun, and it is difficult to clean the welding gun; 2. During cleaning, the welding gun needs to be aligned with the position of the reamer, so the robot welding system needs to be programmed to align, and since there are various uncertainties in the production process, such as the deviation of the welding gun assembly, the change of the position of the reamer itself, the wear and deformation of the reamer, etc., which will affect the cleaning effect, and even cause damage to the machine parts during the strong cleaning process.
