Tungsten Carbide Composite Welding Rods Hardfacing Rod for Oilfield Milling Shoe&Downhole Fishing Tools WC Overlay Welding Rod

No.1601586621961

Tungsten Carbide Composite Welding Rods are hardfacing welding consumables with tungsten carbide particles embedded in a metallic alloy matrix.

When welded on carbon steel or alloy steel surfaces, they build up a high-hardness anti-abrasion layer to resist sand, gravel and mineral abrasion.
Common applications: mining tools, drill bits, earthmoving blades, oil & gas wear parts, agricultural cutting tools.
Features: outstanding abrasive wear resistance, easy operation, good metallurgical bonding with base metal.

Tungsten Carbide Composite Welding Rods

Advantages:

1. High tungsten carbide granular content, outstanding abrasion resistance
2. Low dilution rate, maintains high hardness after overlay welding
3. Strong metallurgical bonding, hardfacing layer not easy to peel off
4. Stable welding performance, less spatter, easy operation
5. Resist impact & sand erosion, ideal for oilfield milling shoes /fishing tools
6. Uniform WC particle distribution, consistent service life
7. Wide application: oilfield downhole tools, drill bits, mining wear parts
8. Customizable rod diameter & WC particle size

Zhuzhou Jinzhou Tungsten Carbide Composite Welding Rod, also called Tungsten Carbide Welding Electrode, Carbide Brazing Rods or Carbide Welding Bars, is made of granular alloy and elastic matrix carbide. We have two options: Brass Copper Matrix Composite Rods and Nickle Matrix Composite rod. there is a special flux on the surface and colored in order to identify the granular size.

The main composition of sintering tungsten carbide scrap is mainly CO and WC, The hardness is about HRA 89~91, Matrix body is Ni or Brass Copper Alloy, strength can up to 690MPa, hardness HB≥160.

It is mainly used to overlay the worn-out and cutting usage workpieces in oil,mining,coal mining,geology,construction and other industries.Such as:milling shoes,wear shoes, junk mills, milling shoes, centralizers,reamer,drill pipe joints,hydraulic cutter,scraper blade plow planer,drill core, piling drill,auger,etc.
