Description

Technical Field

[0002] The compressor is one of the most important components in an industrial refrigeration system, and its performance and health directly affect the working efficiency and stability of the entire refrigeration system. During the operation of the compressor, a certain gap needs to be left between the rotor and the stator to prevent friction, wear, and collision. However, this gap can cause leakage of gas or lubricating oil. The leakage not only reduces the working efficiency of the compressor but may also lead to serious consequences such as environmental pollution and even explosion. Therefore, it is crucial to produce a leak-proof compressor housing.

[0003] Pulse welding is a technical method that uses a strong current for welding. By precisely controlling the welding process, the tightness of the weld of the compressor housing can be ensured, effectively preventing refrigerant leakage, ensuring the normal operation and efficient refrigeration of the compressor. When welding the internal gap of the compressor housing, since the welding torch head cannot be deflected, the welding efficiency is reduced, and the welding quality is affected.
