D-667 high chromium cast iron electrode wear: This electrode surfacing in the low, medium carbon steel, low alloy steel, high manganese steel and cast iron parts surface. Able to withstand high impact wear, hardness after welding HRC ≥ 55-65. Below the high temperature of 500 ℃ has good resistance to wear, corrosion and cavitation-resistant capability. Generally 3-8 times can increase the life of the weldment. This electrode can be multi-layered surfacing, surfacing layer to achieve the best results (because the basic surfacing layer electrode composition, base metal composition rarely appropriate) surfacing total thickness of not more than 1 cm. Wear parts suitable for surfacing operation in high temperature conditions (such as: the ring burning furnace discharge plow Ploughshares better). Surfacing by better wear parts (such as: mining and cement plant crusher tooth plate) D-266 high-manganese steel surfacing used in conjunction with the effect of the economy operating under a strong impact. Electrode in use, according to the instructions for use, before welding electrode drying, the weldments cleaning preheated slow cooling after welding. D-698 graphite coating welding electrodes, AC and DC. For mineral machinery and soil sediment stone grinding the strong wear parts surfacing. Deposited metal hardness HRC ≥ 60. D-707 tungsten carbide welding electrode wear: low carbon steel core hydrogen the sodium tungsten carbide electrode, DCRP. Suitable for concrete mixer blade, bulldozers, high-speed sand box, dredging machine blades, etc.. Deposited metal hardness HRC ≥ 63-75. D802 D812: valve cobalt-based electrode: casting cobalt-chromium-tungsten alloy surfacing electrode welding core drug skin surfacing electrode by dipping into the legal system should DCRP. The surfacing metal at 1000 ℃ still has good wear resistance and corrosion resistance. Usage: suitable for high-temperature and high-pressure valves, high pressure pump shaft sleeve and the inner sleeve, and chemical fiber equipment the chopping blade mouth and other parts of the surfacing. The surfacing layer hardness HRC ≥ 40 Notes: 1, before welding electrodes shall more than about 200 ℃ bake 1 hour re-applied welding. Short arc as far as possible, welding, and welding rod work remains vertical. 3, according to the size and the kind of the base material of the work subject to the 300 ~ 600 ℃ preheating. Should adopt a small current short arc welding. After welding, one hour after tempering at 600 ~ 700 ℃ in the slow cooling or slow cooling immediately placed in dry and hot sand box or kelp, to avoid cracks. 5, surfacing layer shall be subject to the kibble, such defects, according to the above steps for welding and slow cooling. Cobalt-based hardfacing welding wire Description: surfacing D802 wire casting cobalt-chromium-tungsten alloy core welding wire welding, surfacing with a wire core wire by dipping into the legal system, deposited metal at 1000 ℃ still has good abrasion resistance and corrosion resistance. Usage: suitable for high-temperature and high-pressure valves, high pressure pump shaft sleeve and the inner sleeve, and chemical fiber equipment the chopping blade mouth and other parts of the surfacing. Weld metal chemical ingredients (%) C of 1.0 ~~ 1.7 Cr 26.0 ~~ 32.0 W 7.0 ~~ 10.0 Mn ≤ 2.0 Si ≤ 2.0 Fe ≤ 3.0 Co margin surfacing layer hardness HRC ≥ 40 specifications φmm 2.5 3.0 D968: graphite coating, welding electrodes, AC and DC. The deposited metal hardness HRC: 61 to 66. The YM602W-Cr-B: graphite coating, both AC and DC, suitable for carbon steel, cast steel, manganese steel base metal coated welding. Weld layer play against the role of external high intensity wear, such as on various devices strong grindability member. The deposited metal hardness HRC: 61 to 66. D-708: tungsten carbide welding electrode wear: contains a variety of wear-resistant alloy material, DC welding. Apply to strongly surfacing resistant rocks wear of mechanical parts, such as leaf blowers, concrete mixer blade, hammerhead pink stone, charcoal machine spiral surface wear parts repair. Deposited metal hardness HRC ≥ 70.
