Abstract: To provide a low-distortion compressor by controlling heat affects resulting from welding while sufficiently ensuring the welding strength of a casing and an inside part, or a body portion casing and end portion casings. A method for producing a compressor (1, 101) of the present invention comprises an aligning step and a welding step. The compressor is disposed with a casing (10, 11, 111) and an inside part (60, 125) that is housed in the casing. The casing includes a first portion (11a, 11w, 111w) on its inner surface (11s, 111s), and the inside part includes a second portion (60a, 61, 125b). The second portion faces the first portion. In the aligning step, the first portion and the second portion are caused to face each other. In the laser welding step, laser light is applied to at least part of the portion where the first portion and the second portion face each other, whereby the casing and the inside part are laser-welded together.

Abstract: PROBLEM TO BE SOLVED: To suppress the thickness of a wrap of a scroll member to increase the capacity, secure strength, and suppress the deformation amount of the wrap within an allowable range.
SOLUTION: A fixed scroll member 126 of a compressor is equipped with a mirror surface 186a and the wrap 187. The wrap 187 having a spiral shape extends perpendicularly from the mirror surface 186a. In the wrap 187, a surface IS87a1 on the inner peripheral side of a part 187a near the winding start positioned near the center is inclined by only an angle θ with respect to a line orthogonal to the mirror surface 186a. Further, the inclination angle of other surfaces OS187a, IS187b, and OS187b of the wrap 187 with respect to the line orthogonal to the mirror surface 186a is zero.
