Claim 16:
17. A method for manufacturing a compressor, the method comprising:
housing a housing inside a tubular barrel casing;
welding the tubular barrel casing and the housing together to form a first weld; and
circumference welding the tubular barrel casing and an end casing together from a predetermined welding start area along a circumferential direction of the tubular barrel casing so as to reduce deformation of the tubular barrel casing to form a second weld, by which the tubular barrel casing and the end casing are joined together over an entire circumference of the tubular barrel casing, the end casing covering an opening of an end portion of the tubular barrel casing,
the predetermined welding start area being located at a location aligned with the first weld along an axial direction of the tubular barrel casing, and end portions welded overlapping each other at the predetermined welding start area,
with respect to the circumferential direction of the barrel casing, a width of the second weld to a width of the first weld aligned with the second weld along the axial direction, the width of the second weld is larger than or equal to the width of the first weld, and
the formed second weld being
a single second weld having a substantially circular shape or
a pair of second welds each having a substantially semicircular arc shape.
