Description

Technical Field

[0001] The invention specifically relates to an explosion-proof welding tool for a single-pass aluminum shell. Background Art

[0002] Single-pass aluminum shell usually refers to an aluminum alloy shell used to protect and support equipment or components. This shell has an assembly opening on the top and a small pressure relief port at the bottom welded with an explosion-proof valve to relieve the higher pressure inside the aluminum shell. It has a simple design, is easy to dissipate heat, and has good strength and corrosion resistance.

[0003] When the existing single-pass aluminum shell is welded and fixed with the explosion-proof valve plate, it is necessary to manually and accurately place the explosion-proof valve plate to a specific position on the single-pass aluminum shell. However, the explosion-proof valve plate is not easy to position, resulting in deviations during manual placement. In addition, if the explosion-proof valve plate moves during the welding process, it will also cause defects after welding. It is not convenient to fix the explosion-proof valve plate immediately after placement, and the operation is inconvenient. For this reason, we propose an explosion-proof welding tooling for a single-pass aluminum shell. Summary of the invention
