MIG Weld Deposition, Submerged Arc Welding
In these arc welding processes, consumable hardfacing wire is fed continuously from a spool through the welding torch into the arc, where it is melted and transferred to the workpiece In the case of MIG welding, also known as Gas Metal Arc Welding (GMAW), the weld pool is protected from the atmosphere by a stream of shielding gas.
The MIG process is very flexible — it can be partially or fully mechanized and is suitable for a wide range of applications.Wire is also used as the hardfacing consumable in the Submerged Arc Welding (SAW) process. In this process, a mineral-based fluxing powder flows around the consumable wire and is melted by the arc. It forms a gaseous shield around the arc and also forms a slag on top of the weld pool, shielding the cooling weld pool from the atmosphere..
Cored Wires are available in these standard diameters:
- 1,2mm— supplied in 15 kg spools
- 1,6mm— supplied in 15 kg spools
- 2,4mm— typically supplied in 25 kg spools (optionally in 15 kg spools)
- 3,2mm(special order) — supplied in 15 kg spools
