Hard Facing Material of Standard Tungchip Tungsten Carbide Grit Tungsten Carbide Composite Welding Rod

1、 Product introduction
Cemented carbide electrode, also known as YD type cemented carbide composite electrode (YD type electrode for short, commonly known as wolverine rod) is made of granular sintered cemented carbide and elastic matrix alloy. The sintered cemented carbide particles are mainly cobalt-containing tungsten carbide or titanium carbide, and its hardness can reach 89-91HRA. The matrix metal is generally "nickel copper" alloy, with bending strength of about 690Mpa and hardness ≥ 160HB. The cemented carbide composite electrode needs to be used with a backing electrode and a flux.

Application industry of wear-resistant YD hard alloy surfacing welding rod

3、Advantages of cemented carbide composite electrode products
(1) Good stability, all alloy particles are made of broken anvil material, and the product composition is consistent.
(2) Good wear resistance, carefully screen alloy particles to ensure that the particles are full, making the product more wear-resistant.
(3) Good weldability, unique solder, ensure the fluidity of welding rod, and make it easier to weld.

4、 Product surfacing process and precautions
(1) Surfacing process: YD type electrode is used for surfacing with oxygen-acetylene flame. The gas welding nozzle used shall be larger than that used for ordinary gas welding of carbon steel. The flame shall be adjusted to neutral or slightly carbonized flame. The tip position of the neutral flame core should be strictly controlled, and it should not contact hard alloy particles and workpiece surfaces to avoid overheating, which means that the welding tip lift is higher than that of ordinary gas welding. This is the key to affecting the wear-resistant life of the surfacing layer, and should not be ignored.
(2) The flat welding position shall be used as far as possible during surfacing, and the appropriate mould shall be used for surfacing at other positions.
(3) The work site must be well ventilated to avoid harm to health.
