[0002] The guide tube for ship propeller is an important component in the ship propulsion system. The water flows to the propeller under the guidance of the guide tube, which can concentrate and rectify the water flow, so that the water flow hits the propeller blades at a more appropriate angle and speed. The propeller rotates and does work to push the water flow backward, and the guide tube helps to increase the axial speed of the water flow, thereby improving the propulsion efficiency of the propeller. At the same time, the guide tube can also reduce the rotational energy loss of the propeller wake and convert more energy into the propulsion force of the ship.

[0051] When the flow guide tube 2 in transmission passes through the bottom of the welding gun 5, the welding gun 5 effectively realizes the welding processing of the notch on the top of the flow guide tube 2. During the welding process, the welding controller 63 realizes the precise control of the welding gun 5 to ensure the quality of welding.
