PURPOSE: An apparatus for welding a compressed part of a hermetic rotary compressor is provided to minimize transformation of a mechanical part due to welding by indirectly welding a compression pump housing to a case. CONSTITUTION: A compression pump housing is installed inside a hermetic container, having a refrigerant gas compression space(8) inside. A plurality of indirect welding connection elements are fixed at the compression pump housing to fix the compression pump housing at a case of the hermetic container. The compression pump housing is fixed by fixing the indirect welding connection elements at the case. The compression pump housing is formed of a cylinder(9) installed inside the hermetic container, and a main bearing(10) and a sub-bearing(1) fixed at upper and lower parts of the cylinder.
