Description

TECHNICAL FIELD

[0002] In modern manufacturing industry, metal welding is a key process for building metal structural parts, and is widely used in aerospace, automobile manufacturing, shipbuilding industry, construction engineering and other fields. With the increasing requirements of precision, strength and production efficiency of metal structural parts, the importance of metal welding tooling is increasingly prominent. Automatic and semi-automatic electric arc welding machines can complete the welding of metal parts in various working conditions due to their flexible operation and strong adaptability. Plasma arc welding machines have the advantages of high energy density, fast welding speed and excellent welding quality, and are used in automobile manufacturing industry to meet the welding requirements of automobile handrail skeletons. Therefore, a metal welding tooling is needed.

[0003] As for the current traditional metal welding tooling, the existing process relies on manual support of metal skeletons to complete splicing and welding operations.

During the welding process of automatic, semi-automatic electric arc welding and plasma arc welding, high-temperature molten slag and metal debris may splash and eject, which can cause burns and cuts to operators, posing a serious threat to personal safety.
