Surfacing welding can significantly improve the service lifetime of metal parts, saving manufacturing cost, shortening repair and replacement time , reducing machine shutdown time, so as to improve productivity. Welding also can obtain the excellent overall performance and realize rational use of the materials, has great significance to improve product design.

At present, main surfacing welding methods are laser welding, plasma welding, submerged arc welding, and open arc welding introduced from oversea.
1.Submerged arc welding, high production efficiency, high welding quality and stability
2.Open arc welding, a self protection technology using flux-cored welding wire, do not need any welding flux, pattern swing welding is available
3.Laser welding, can preciously control the heat input, high welding speed, fast cooling, also make a better thickness, composition and dilution rate control-ability, hardfacing layer had more compact structure, excellent performance
4.plasma surfacing, has advantages of high efficiency, high speed, low dilution and deformation.

Zhangjiagang YaoYu VAUTID chromium carbide overlay plate produced by open arc welding machine and has more than 30 production lines, ensure high quality and fast delivery.
