Assembly of aluminum components by soldering, uses tongues on joining ring to engage hollows in surface of components to hold components in place during soldering

摘要

The aluminum components are pre-assembled and held in position without application of force to hold them together. The components clip together, with hollows (31) on the surface of the components (21,22) locking with tongues (30) inside joining rings (25) that accept the ends of the components.
