Tungsten Carbide Tube Welding Rod
Mild-steel-sheath tube rods filled with WC for oxy-acetylene hardfacing.
This series of tungsten carbide tubular hardfacing electrodes, with a mild steel sheath filled with high-hardness tungsten carbide phases, are engineered for oxy-acetylene flame hardfacing. Tested per ASTM G65, the dense, metallurgically bonded deposit delivers 6-7 times the wear resistance of conventional materials with low carbide burn-off.
With a standard filling rate of 60%-65%, the product line includes four variants for targeted performance: cast tungsten carbide, cemented carbide grit, carbide pellet and monocrystal WC, with customizable particle size, diameter and filling ratio.
Widely used in oil drilling, mining and construction machinery, it is ideal for surface strengthening and repair of drill bits, conveyor blades, crusher hammers and other wear-prone components, cutting maintenance costs via extended service life.

How to Specify & Apply
Identify the Service Envelope
Determine the dominant wear mode (abrasion, erosion, adhesion, corrosion, oxidation), operating temperature and impact load. This narrows the grade selection to 2-3 candidates.
Match the Process
Each grade is validated for specific deposition processes. The "Application Process" field above shows HVOF, HVAF, APS, PTA, LMD, OFS or CAW compatibility.
Choose the Particle Size
Particle size controls deposit density and surface finish. Fine cuts (15-30um) for thin dense coatings; coarser cuts (45-90um) for thick build-up and high deposition rate.
Request a Sample
Most grades ship with a 1-2 kg sample for in-house process qualification. Our engineers will support parameter development on your equipment.
