Description

A precious metal cold welding device with high precision

technical field

The utility model relates to the technical field of welding devices, in particular to a high-precision noble metal cold welding device.

Background technique

The cold welding machine uses the charging capacitor to discharge in a period of 10-3 to 10-1 seconds and an ultra-short time of 10-6 to 10-5 seconds. The contact part between the electrode material and the workpiece will be heated to 8000°C~10000°C in an instant, and the molten metal in the plasma state will transition to the surface layer of the workpiece in a metallurgical manner. The diameter of the electrode used is less than 4.0mm. When the precious metal is used, the use of too thick welding rod will lead to low precision of precious metal repair. Therefore, we propose a high-precision precious metal cold welding device.
