[0002] In the manufacturing process of heat exchangers, U-shaped welded pipes are an important component, and their welding quality directly affects the performance and service life of the heat exchanger. Currently, U-shaped pipe welding machines have become key auxiliary equipment for welding U-shaped welded pipes in heat exchangers.

[0003] Existing common U-tube welding machines operate by placing the welding position on the surface of the pipe, followed by the operator pulling on the arc-shaped covers on both sides of the welding position to close them before welding. However, this method has significant drawbacks. Because the operator needs to reach into the narrow space between the pipes to pull the arc-shaped covers, operation is extremely inconvenient. Firstly, the limited operating space greatly increases the difficulty of operation, wasting considerable time and energy and severely impacting welding efficiency. Secondly, operating in this confined space makes it difficult for the operator to precisely control the closing action of the arc-shaped covers, easily leading to incomplete closure and affecting the stability of welding quality, thus failing to meet the high-quality production requirements of heat exchangers.
