B-ARC

The new Welbee B-Arc technology from OTC DAIHEN, market leader in the welding industry.

Highly efficient welding system for heavy steel plates: B-Arc welding

• The invented OTC DAIHEN proprietary buried arc welding technology whose wire is buried deep in the metal base, resulting in deeper penetration as deeper part of the metal base is heated.
• One pass welding with a maximum thickness of 19 mm and reduction of the welding time by up to 80% (for butt welding plate thickness of 19 mm, welding length 1 m)
• Drastic reduction of groove processing time – One pass welding leads to less groove processing, resulting in reduced processing costs.
• Significant reduction in wire consumption, up to 70% due to reduced edge preparation space.
• Stabilization of high current buried arc. Multilayer welding Applications: Users of thick plate welding for steel frames, bridges, ship building, plant pipes, etc..
