AI Technical Summary
Technical Problem
Existing hermetic containers for compressors face challenges in achieving stable airtightness due to incomplete brazing around the circumference, leading to potential leaks and reduced performance.
Method used
A sealed container design with a cylindrical body and lid, featuring a punched portion formed by punching and resistance welding, ensuring the lid is fixed around the entire inner circumference to enhance airtightness.
Benefits of technology
The resistance welding process stabilizes the welding and improves airtightness, preventing deformation and reducing manufacturing costs while maintaining high assembly precision.

Abstract
This sealed container for a compressor has a tubular body, and a lid that is provided on one end side of the body in an axial direction. The body comprises a curved section that is integrally formed on the one end side and is formed into a convex curve, the lid being fixed to said curved section. The curved section comprises a punched section that is formed by punching the one end side using a punch and a die. A droop and a shear surface are formed on the inner peripheral surface of the punched section, from the outside toward the inside of the punched section. The lid is fixed to the entire inner periphery of the punch section by resistance welding.
