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. |
