Tube Welding Rode (Wire) for Wear Resistance Application
 
■ A kind of particulate-abrasion-resistant and drilling-wear-resistant tubular built-up welding electrode with high hardness
■ Filled up with the homogeneous mixture of hard phase tungsten, tungsten compound and other metal additions
■ Built-up welding by brass solder, metallurgical joint is formed between built-up welding metal and the welded metal. Especially suitable for built-up welding of petroleum-exploiting and mining tool (for example: steel-tooth drill) and mechanical parts that is subject to strong abrasion of rock and sand

Sintered WC/super-hard WC composite material
High wear resistance and impact resistance, specially used for surface built-up welding of petroleum, gas prospecting tool.
 
Note: Normally Φ4×600 is supplied unless otherwise specified.
 
Cautions as welding: 1.Preheating the part to 450℃-650℃ according to part shape size and material.
  2.Light carbonization blaze welding.
  3.Control matrix metal temperature to melting point when welding, then cool slowly after welding.
