“硬面焊接”是机械零件表面复合强化的一种方法,始于1896年。因添加于母材表面的金属膜是高硬度材料,故称“硬面焊接”。1920年在石油钻井机和工具上采用并广为推行。胶焊与氧乙炔管状焊丝并用的“硬面焊接”就是由此演化发展起来的一项耐磨零件表面堆焊法,可用于工程机械中某些零件的预焊和修补。 “Hardface welding” is a method of mechanical strengthening of the surface of parts, beginning in 1896. Due to added to the surface of the base metal film is a high hardness material, it is called “hard surface welding.” Adopted and widely implemented on oil rigs and tools in 1920. Welding and oxyacetylene tubular welding wire used in conjunction with the “hard welding” is the evolution of the development of a wear-resistant parts surfacing surface method can be used for some parts of the construction machinery pre-welding and repair.
