Metco Joining & Cladding offers a wide range of materials for surfacing using arc welding processes. These products are thoughtfully designed with various types of carbides to provide maximum wear resistance and durability.
Our products include surfacing materials for the following arc welding processes:
- GMAW: Gas metal arc welding (MIG)
- GTAW: Gas tungsten arc welding (TIG)
- OA: Open arc welding (e.g., without gas)
- MMAW: Manual metal arc welding
- SAW: Submerged arc welding
- SAW-BPW: Submerged arc bulk powder welding
Our portfolio includes:
- Composite wires
- Powders
- Cast tungsten carbide *
- Monocrystalline tungsten carbide *
- Carbide sinter pellets *
- Rods
- Electrodes
(* for customer blending with an appropriate matrix material)
When we develop a material for arc welding surfacing, we first consider the needs of our customers and the arc welding process to be used. We then use our own in-house expertise to develop innovative products that exceed customer expectations. We carefully consider:
- Sheath alloy and thickness (composite wires)
- Optimal fill rate (composite wires)
- Relationship of the sheath to fill for more effective application (composite wires)
- The best type of carbide for the process and application
- How to achieve better control of the fluidity of the weld pool
- How can we reduce spatter and smoke
- Compositions that minimize cracking or weld crack-free
