MIG Welding

MIG or FCAW is a semi automatic or full automatic machine that uses CO2 for welding

Special features:

1. Relatively high deposition rates with excellent quality welds are normally obtained. 
2. The process is suit­able for automated repetitive weld over­lay requirements. 
3. The shielding gas can be argon, helium or mixtures with CO2 etc depending on the requirements.
4. The consumable is in the form of a wire typi­cally 1..2 mm or 1.6 mrn. One variation is the use of tubular metal cored wires      containing metallic alloying elements plus de-oxidants in powder form in the core. 
5. The process is extensively used for repair and resurfacing of railway cross­ings, crushing hammers in cement plants, coal crushing hammers in power plants and concast rolls in steel plants GMA W can be used to clad bores of pipes and valves with openings less than 25 mm with wear and corrosion resistant alloys.
