Description

Technical Field

[0001] The utility model relates to the field of welding devices, in particular to a welding monitoring and positioning tool for a thermal protector. Background Art

[0002] Welding equipment refers to the equipment required to implement the welding process, including welding machines, welding process equipment and welding auxiliary tools.

[0003] A thermal protector is a temperature controller composed of two different alloys. The manufacturing process of the thermal protector is to weld the upper metal sheet to the thermal protector base. During the welding process, the thermal protector needs to be placed on the thermal protector fixed base first, and then the metal sheet is inserted into the groove on the thermal protector. Finally, the metal sheet is welded and fixed by a welding device. During this process, because part of the thermal protector base is a circular structure, it is necessary to manually adjust its direction to ensure that the welding head of the welding device is aligned with the metal sheet during welding. However, manual adjustment is inefficient and positional deviations may occur. Therefore, a positioning tool is needed to replace manual adjustment of the thermal protector base.
