Description

Technical Field

[0001] The present application belongs to the technical field of metal processing, and in particular relates to a double-sided shielding gas device for nonferrous metal welding. Background Art

[0002] Nonferrous metals are difficult to weld because they are chemically active and react with gases such as hydrogen, nitrogen and oxygen at high temperatures to form brittle compounds, which not only significantly deteriorate their plasticity and toughness, but also dramatically reduce their corrosion resistance. If the weld joint is oxidized during welding, even if it is treated, the corrosion resistance will be affected to some extent.

[0003] When using a welding gun to weld non-ferrous metals, the back side needs to be protected. Generally, this is done manually by dragging a box body, that is, the box needs to be manually held and moved along the weld during welding. This not only wastes manpower and material resources, but also blocks vision due to the fit between the box body and the weld during welding. It is easy to fail to keep up with the molten pool and miss protection, thus affecting the welding quality. Utility Model Content
