High frequency welding characteristics

1. because the current is highly concentrated in the welding area, the heating speed is very fast, so the welding speed can be as high as 150 ~ 200m/min.

2. because the welding speed is fast, the welding part self-cooling effect is strong, so not only the heat affected zone is small, but also not easy to oxidize, so the weld structure and performance are very good.

3. the surface of the weldment can not be cleaned before welding, thus improving the efficiency.

4. can weld a wide variety of metal, product shape specifications.
