Tungsten carbide electrode as tungsten carbide welding rods and tungsten carbide gas welding rod. Cast tungsten carbide gas welding rod a brief description and the ingredient list: Tungsten carbide gas welding rod is the part surface or edge of weld metal layer Abrasion or special performance manufacturing dual metal parts or repair failed shape metal the old part of the process method, cast tungsten carbide gas welding rod is super hard, super- wear-resistant materials. The abrasion resistance is several times the normal electrode wear, to repair deep well drill necessities.   Name brand tungsten carbon free carbon chloride residue hardness HRA Cast tungsten carbide YZ 95-96 3.9 ± 0.1 <0.1 0.25 93-93.7 Tubular cast tungsten carbide gas welding rod, tube component W2C and WC alloy particles, the hardness 93HRA, the melting point of 1600-1800 degrees, using oxygen - acetylene flame surfacing, high wear resistance. Used in petroleum drilling, drilling wells drill, concrete mixing blades, the strong dredging blades, high-speed sand box, charcoal, feed grinder blade wear parts. Tungsten carbide welding rod, Description: D707 is made of carbon steel low hydrogen sodium type core welding tungsten carbide hardfacing welding rod, rely the drug skin carbide alloy transition, surfacing metal tungsten content of 40-50%, due to drug skin thicker and thus the sleeve longer in the welding process, drug skin redness easy small pieces off, so it is appropriate to the the DCRP smaller current.   Uses: Used for surfacing resistant to the rock strongly wear of mechanical parts, concrete mixer blade, bulldozers and pump blade, dredge blades, high speed sand box.   Chemical composition of deposited metal chemical composition (%) C Mn Si W Guarantee the value of 1.50 ~ 3.00 ≤ 2.00 ≤ 4.00 40.0 ~ 50.0   Surfacing layer hardness: HRC ≥ 65 ~ 68. Representation is not the same as two kinds of electrode hardness, the welding rod generally HRC maximum only 70. Gas welding rod used for the HRA, said welding rod Hebei many say can reach more than 70, that is a lie. Gas welding rod welding electrodes in accordance with the wear resistance, good times more, of course, the price is also expensive, welding several times.
