Cast Tungsten Carbide Welding Rod

Cast tungsten carbide welding rods

Description: this is electrode containing tungsten powder, high wear resistance of boron powder and alloy powder welding wire, high hardness, wear resistance, impact resistance, high temperature resistant. Oxygen - acetylene temperature: 1000 ~ 2800 degrees.Tungsten content is 65% - 85%, granularity: 30 yard to 80 yard.
USES and features: the YZ casting tungsten carbide wear-resistant welding wire, the welding welding with high abrasion resistance and impact resistance.Widely used in petroleum drilling
Stranded, engineering machinery, screw propeller (dragon), exhaust fan impeller blades, blender blades, mud pump, such as the coal chute surfacing, crusher blade
, mining machinery, coal drill pipe, sugar cane knives, etc. High hardness, resistance to rock sand abrasive wear.Extend the service life of equipment 6 to 7 times. HB p. 90-95
Surfacing note: 1, tungsten electrode, with oxygen - acetylene welding, use the carbonizing flame, welding temperature control at 1700 ºC, must be surfacing welding workpiece preheating, welding surface local ministry of 850 ºC to 950 ºC heating up again.                   
2, should know welding workpiece material, different material with different electrode
To get satisfactory results
3, surfacing welding workpiece, should remove rust, impurity and oil pollution.
