Abstract
A compressor includes a casing, a housing inside the casing, and first and second welds. The casing includes a tubular barrel casing and an end casing. The first weld welds the barrel casing and the housing together. The second weld welds the barrel casing and the end casing together along a circumferential direction. The second weld includes a repeatedly welded portion formed by one end portion and an other end portion of the second weld overlapping each other, or the second weld includes a plurality of second welds each including a repeatedly welded portion formed by an end portion of the second weld and an end portion of an other one of the second welds overlapping each other. The repeatedly welded portion are formed to reduce deformation of the barrel casing. The repeatedly welded portion and the first weld are aligned along an axial direction of the barrel casing.
