WC-CO Cemented Sintered Carbide Welding Rod 440-450MM

Description of Carbide Composite Rods:

Tungsten carbide composite rods, specifically designed for safeguarding high-wear components in the oil and gas drilling, geothermal, mining, and geological exploration industries, cater to a range of critical equipment such as washover shoes, stabilizers, down-the-hole drill bits, reamers, drill rods & subs, and more.

KINGTOOLS proudly manufactures high-caliber tungsten carbide welding rods, meticulously crafted from sintered tungsten carbide particles and a high-tensile alloy. The welding rod substrate is meticulously selected from copper or nickel, with the coating serving both a functional and identifying role. The application of the tungsten carbide welding electrode is executed through the oxyacetylene brazing method.

For precision cutting applications, tungsten carbide hardfacing welding rods featuring larger particles are recommended, while smaller particles are preferred for applications requiring enhanced wear resistance.

Advantages of Carbide Composite 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

Applications of Carbide Composite Rods:

Carbide compositerod has wear andcutting properties coupled by high-endweldability and low fuming, allowingthe material to use in stabilizersreamers, drill pipe joints, constructiondrilling, hydraulic-cutter, twist drill,etc.
