COMPRESSOR MANUFACTURING METHOD AND COMPRESSOR Russian patent published in 2010 - IPC F04C29/00 

FIELD: machine building.

SUBSTANCE: compressor manufacturing method involves equalisation phase and welding phase. Compressor is equipped with housing and inner part 60 which is located in housing. Housing includes the first part 11a on its inner surface, and inner part includes the second part 60a. The second part 60a faces the first part 11a. At the equalisation phase the first part 11a and the second part 60a are located one opposite the other. At the laser welding phase the laser beam is directed at least towards the part of the section, where first part 11a and second part 60a face each other, thus welding the housing and inner part 60a with laser welding. At laser welding phase, fusion place 70 of first part 11a and second part 60a, to which the laser beam is directed, and which is molten, takes the shape of open curve if to look in the direction perpendicular to first part 11a and second part 60a.

EFFECT: providing positioning accuracy of inner part 60a of the housing.
