Scroll Compressor Weld Layout for Barrel Casing Deformation Control

The welding process is segmented into multiple sequential welds (first weld, second weld, third weld) rather than attempting to complete all welding in one operation. Each weld is performed at a different location and orientation, allowing the barrel casing to cool and stabilize between welding operations, thereby reducing cumulative thermal deformation while maintaining manufacturing feasibility

The first weld is performed on the barrel casing before the end casing is fully assembled, and subsequent welds are performed in a predetermined sequence. This preliminary action approach allows for controlled thermal input and enables deformation management by completing welds in an optimal order rather than simultaneously or in reverse sequence

The welding process employs periodic action by performing welds at distinct intervals rather than continuously. The first weld, second weld, and third weld are executed with cooling periods in between, allowing thermal management that prevents excessive deformation while maintaining a structured, repeatable process rhythm that can be optimized for production timing

Each weld is performed at a specific location with particular quality requirements (first weld at initial position, second weld at different position, third weld at another position). This local quality approach ensures that critical sealing areas receive appropriate welding attention while allowing less critical areas to be welded later or with different parameters, balancing overall manufacturing efficiency with localized sealing performance
