Cast tungsten carbide electrode properties: tungsten powder, boron powder and alloy powder composed of high wear-resistant gas welding rod, high hardness, wear resistance, impact resistance, high temperature resistance.Oxygen-acetylene temperature: 1000~2800ºC.Tungsten content of 65%-85%, particle size 30 mesh -80 mesh.

Use and characteristics of cast tungsten carbide electrode: YZ cast tungsten carbide wear-resistant gas welding rod, the use of gas welding has high wear resistance and impact resistance.Widely used in oil drilling tools, engineering machinery, screw propeller (winch) blade, exhaust fan impeller, mixer blade, mud pump, coal mine chute and other surfacing, grinding machine blade, mining machinery, coal mine drill pipe, sugar cane pressing knife.High hardness and resistance to rock abrasive wear.Prolong the life of the equipment by 6-7 times.HRC 80 or more

Precautions for surfacing:

1, tungsten carbide electrode, surfacing with oxygen-acetylene, the use of carbonization flame, welding temperature control at 1700ºC, the surfacing workpiece must be preheated, surfacing surface local heating 850ºC-950ºC welding.

2, we should know the material of the surfacing workpiece, different materials to choose different electrode to get a satisfactory effect.

3, surfacing workpiece should be removed rust, impurities, oil.

4, such as the surfacing workpiece area is large and thick, can first use steel or 422 electrode welding into a certain size, then surfacing wear-resistant electrode or impact wear resistance cast tungsten carbide electrode tube composition for W2C and WC alloy particles, hardness 79HRA, melting point 1600-1800 degrees, the use of oxygen - acetylene flame surfacing, has high wear resistance.It is suitable for surfacing welding of oil drilling tool, drilling bit, concrete mixing blade, dredger blade, high speed sand mixing box, screw propeller of charcoal machine, blade of feed grinder and other parts which are easy to wear.
