Description

Technical Field

[0001] This utility model relates to the field of cold welding machine technology, specifically to a dental cold welding machine. Background Technology

[0002] Cold welding machines utilize the high heat energy generated by the instantaneous discharge of a charging capacitor to instantly heat the contact area between the electrode material and the workpiece to an extremely high temperature, achieving low-temperature welding through instantaneous discharge, hence the name "cold welding". Compared to traditional hot welding, it has less impact on materials, thus having advantages in some applications that are sensitive to material temperature.

[0003] Existing dental cold welding machines are precision welding devices used in the field of oral medicine. They are mainly used in orthodontic treatment, implant restoration, and denture fabrication. These cold welding machines have complex structures, large sizes, and are inconvenient to move and carry, resulting in poor convenience. They also make it difficult to inspect and repair internal components.
