The all-new Welbee D-Arc technology from OTC DAIHEN, market leader in welding industry
Highly Efficient Welding System For Heavy Steel Plate: D-Arc Welding
- OTC DAIHEN’s owned invented Buried-arc welding technology of which wire is buried deeply in base metal, resulting in deeper penetration as deeper part of base metal is heated.
- One pass welding with a maximum thickness of 19 mm and reduction of welding time by up to 80% (for plate thickness 19 mm butt weld, welding length 1 m)
- Drastic reduction of groove processing time – One pass welding leads to less groove processing, resulting in processing cost reduction.
- Significant wire consumption reduction, up to 70% due to edge preparation space reduction.
- Stabilization of high current buried arc
- Multi-layer welding
Applications: Thick plate welding users for steel frames,bridge,ship building,plant piping,etc
