Description

Technical Field

[0001] The utility model belongs to the technical field of welding machines, in particular to a welding machine with a positioning function. Background Art

[0002] Welding machines can make two separate parts bonded without glue to achieve watertightness. Welding machines use electrical energy to instantly convert electrical energy into heat energy. Welding machines are suitable for working in a dry environment and do not require too many requirements. They are widely used in various fields due to their small size, simple operation, convenience, fast speed, and strong welds after welding. They are especially practical for parts that require very high strength. They can instantly and permanently connect the same metal materials (dissimilar metals can also be connected, but the welding methods are different). After heat treatment, the weld has the same strength as the parent material.

[0003] At present, in the field of automobile manufacturing, it is necessary to weld nuts on automobile parts. In existing welding machines, the operator generally places the nuts to be welded and the workpiece under the welding head for welding.
