Document Type and Number:
WIPO Patent Application WO/2022/148069
Kind Code:
A1
Abstract:
A compressor (100), comprising a pump body (20) and a housing (11), wherein the pump body (20) is arranged in the housing (11); the pump body (20) is provided with a welding area (201); and the housing (11) is connected to the welding area (201) by means of laser welding. An assembly method for a compressor comprises the following steps: assembling the pump body (20); placing the assembled pump body (20) in the housing (11); and using a laser welder to be aligned with a position, corresponding to the welding area (201) on the pump body (20), on the outer side of the housing (11), so as to connect the welding area (201) to the housing (11) by means of welding. Laser welding can reduce the amount of deformation of the pump body (20) during welding, thereby avoiding leakage of the pump body (20) caused by welding; and there is no need to provide a welding hole in the housing (11).
