[0002] In the field of heat pipe manufacturing, welding is an important link in the heat pipe production process. Semi-finished heat pipes need to be placed on a specific jig during the welding process to ensure the accuracy and efficiency of welding. However, traditional heat pipe welding jig designs often have problems such as inaccurate positioning, poor stability, and inconvenient operation. These problems will be aggravated when the jig flows through the solder pool, which not only affects the welding quality, but also reduces production efficiency.
