YD carbide surfacing electrode D70 D60 electrode wear resistant welding electrode wear DNJ DX-50 high-alloy electrode wear 

 YD-type carbide surfacing electrode composite materials (the YD-type electrode), is a granular sintered carbide alloy casing with a flexible blend. Coated with a layer of special flux and color to identify the level of particle size. Carbide sintered tungsten carbide particles are mainly cobalt, its hardness is HRA89-91; matrix metal as the "nickel and copper" alloy, tensile strength 690MPa, hardness: HB ≥ 160. 

 ... YD type electrode need a grounding electrode (YD-D) and special flux (YD-R) used in conjunction. I plant both in proportion to matching supply. 

 YD-D rendering is a skin electrode coated with a special flux for welding electrodes, welding rod weight, the amount should be 15% of YD. 

 Carbide composite surfacing electrode 

 YD-R is a complex manufacturing of flux, the dosage should be 2% of the weight of YD electrode. 

 Uses: YD-type electrode is mainly used for welding the oil, mining, coal mining, geology, construction and other industries both in the number of serious wear and tear or cut the workpiece. Such as: milling shoes, wear shoes, centralizers, reamer, drill pipe joints, hydraulic cutting knives, doctor blades, plow plane iron, core drill bits, hammers drill, screw drill and so on. 

 Welding Technology: YD-type electrodes is the use of oxygen - acetylene flame surfacing, the use of the welding tip should be higher than normal carbon steel used in gas welding tip big. The flame should be transferred into a carbon neutral or Shaopian flame. Yan Yan Xin neutral position of the tip should be strictly controlled, can not come into contact with the surface of carbide particles and the workpiece, so as to avoid over-burning, that is, when the tip than the regular welding mention must be high, it is the wear life of cladding layer The key, not ignored. 

 Surfacing weld should be as far as possible the location, other locations should be used for surfacing of appropriate mold.
