YG8 Cemented Carbide Composite Rods Sintered Welding Rod

Description of Composite Welding Rods :

1. Tungsten carbide composite welding rod is made of cemented carbide particles and Ni/Ag(Cu)alloy. The carbide particles always be tungsten carbide crushed grits, carbide wear inserts, like the carbide star shape inserts, carbide pyramid shape inserts, shark shape inserts and so on. Sometimes, the carbide particles can be tungsten carbide powder.
2. The economy choice is tungsten carbide crushed grits. If you want to higher durable than carbide grits, carbide inserts is better. However the cemented carbide/crushed carbide with sharp edge has excellent wear resistance and cutting ability too.
3. The hardness is 89-91 HRA, the binder metal is Ni and copper alloy, strength can up to 690MPa, hardness HB≥160.
4. To brief, most of the Composite rod made using crushed sintered Tungsten Carbide grains bonded with a bronze nickel matrix,(Cu 50 Zn 40 Ni 10) with a low melting point ( 870°C ).

Application of Composite Welding Rods:

Composite rod welding has been acknowledged throughout oil drilling, mining and construction industry worldwide for its extra hardness and high wear resistant properties. The use is even spreading to more industries and gets greater uses. Composite rod welding has wear and cutting properties coupled by high-end weld ability and low fuming, allowing the material to use in stabilizers, reamers, drill pipe joints, construction drilling, hydraulic-cutter, pipe cutter blades, core bit, scraper, twist drill, milling and grinding shoes etc.

Advantages of Composite Welding Rods:

First, to increase the speed ofdownhole milling and cutting.

Second to protect the surface of tools subject, to abrasive wear,maintaining full guage on stabiliz-ers, guides keyseat wipers, andother downhole tools.

• High Strength
• High Hardness
• Abrasion Resistance
• Long Service Life
• Easy to Replace
