YD-type carbide composite surfacing electrode YD-type carbide composite surfacing electrode (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. Sintered carbide particles are mainly cobalt, tungsten carbide, the hardness of HRA89-91; matrix metal as the "nickel-copper 'alloys, tensile strength 690MPa, hardness: HB ≥ 160.

 YD-type electrode with a grounding electrode required (YD-D) and specific flux (YD-R) used in conjunction. Our factory facilities are in proportion to the supply. 
 YD-D rendering is a skin electrode coated with a special flux for welding electrodes, welding rod weight dosage should be 15% of YD. 


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

 Uses: YD-type electrode welding is mainly used for oil, mining, coal mining, geology, construction and other industries both in some serious wear and tear or cut the workpiece. Such as: milling shoes, wear shoes, centralizers, reamer, drill pipe joints, hydraulic cutter, doctor blades, plow planer, core drills, hammers drills, spiral drills.
