Oxygen-free Backing Plate

The Oxygen-Free Backing Plates are welded by the method to insert a specific shape and non-consumable tool between the materials to be welded and to re-crystallize the two materials by the friction stir welding method in solid state at the temperature lower than melting point using the friction heat generated at the two materials.
- No bubble or defect caused by melting
- Excellent strength of welded part (95% of parent material) and abrasion-resistance
- No generation of leak caused by defect or bubbles
- No existence of oxidized layer or inserted foreign substance in the welded part
- Easy welding of large surface (larger than 3m*3m)
- Deep penetration (Max 30t) and rapid production speed (Max 15mm/s)
- Low-cost, environment-friendly, and low-carbon green-growth technology

These Oxygen-Free Backing Plates can be availed at industrial leading price.
