Welding Wire
Solid and flux-cored welding wires for MIG/MAG, arc spray, PTA and laser cladding.
We provide solid and flux-cored welding wires for construction machinery, petrochemical, power, mining and metallurgy industries, supporting dimensional restoration and surface strengthening.
Solid wires feature uniform composition, low spatter and smooth weld formation, compatible with MIG/MAG surfacing, arc spraying and laser cladding. SS420 stainless steel wire delivers moderate hardness and wear & corrosion resistance for hydraulic props, valve seals and molds. Ni20Al nickel-aluminum wire offers high bonding strength and high-temperature oxidation resistance, serving as thermal spray bond coat or boiler tube protection.
Flux-cored wires enable flexible alloy adjustment via core formulation, with high deposition efficiency for heavy-load wear and high-temperature corrosion scenarios. The representative FeCrBSi self-fluxing wire boasts high hardness and excellent abrasive wear resistance, widely used for wear repair of rolls, crusher hammers and conveyor components.

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.
