ABSTRACT:
In a hermetic type compressor including a casing, an electric motor provided in the casing for rotating a driving shaft, and a compressor unit including a cylinder forcibly inserted in the casing, there are provided a method and a device for securing the compressor unit to the casing, wherein reduced thickness portions are provided on the outer surface of the casing so that welding can be carried out from outside of the casing through the reduced thickness portions. In this manner, heat generated in the welded portions can be reduced substantially, and various disadvantages caused thereby can be eliminated.
