Abstract

A method of repairing a scroll compressor, wherein the casing (100) of the compressor is cut open by making two transverse cuts through the casing to give access to the internal components of the compressor. The casing (100) is then resealed, using two annular reinforcing structures (300), one at each cut, to conserve the dimensions of the casing (100). This allows a scroll compressor to be repaired and re-assembled without losing the fine positioning of internal components which are held in place by the casing (100). Each annular reinforcing structure (300) comprises a ring (310) with an outwardly directed flange (305). The flange (305) has a thickness chosen to conserve the dimensions of the re-assembled casing while allowing single-pass welding and the ring (310) has a length which is chosen to provide at least location of the cut surfaces of the casing (100) during re-assembly and, optionally, shielding to prevent weld pool, slag or splatter entering the canister (100).
