Three-dimensional flexible welding tooling its flexible universal characteristics promote it can be applied in all walks of life welding or processing, small to a small exhaust pipe, large enough to be used for dozens of meters of large engineering vehicles (such as trusses, boom, buses, sanitation vehicles, agricultural machinery vehicles, oil derrick, etc.), Of course, it is not only used for manual welding processing, but also with robots or pneumatic elements to achieve automatic welding. It can be used as a production positioning fixture with large output, and it is a very cost-effective good thing for some small batch, many specifications, many categories, or the product application of the sample proofing stage.
