METHOD OF MANUFACTURING SEALED VESSEL FOR COMPRESSOR, SEALED VESSEL FOR COMPRESSOR AND COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a compressor capable of remarkably improving durability, by improving welding strength, even when using a welding difficult material such as aluminum for a sealed vessel. SOLUTION: This sealed vessel 12 for the compressor is formed by welding and fixing the whole periphery of an end cap 12B to a vessel body 12A by blocking up an opening of the vessel body 12A by the end cap 12B. The sealed vessel is characterized by separating a welding starting point of a first layer and a welding starting point of a second layer by 90°or more by welding the vessel body 12A and the end cap 12B by at least two layers.
