MIG (GMAW) Welding Equipment

Blog Archives

This is a versatile process of welding which is suitable both for thin and thick metal sheets. An arc is generated between electrode and work-piece and melt them to a weld pool which is protected by a shielding gas. The wire is feed by wire feeder the direction and speed are controlled by the welder. The process is semi-automatic with competitively priced consumables.
The machine used for the MIG welding process is a MIG welding machine. It is also known as Gas metal arc welding (GMAW) where an electrode is fed continuously, protected with a shielding gas at the electric arc spot and converted to a weld pool which in turn solidifies to form a strong joint.
The MIG welding is recommended for the ease of its use for heavy-duty welding works where Co2 is used with electrodes from wire feeder while Tig is used where strict control over timing, current, and pressure is needed. In TIG welding, non-consumable electrodes with Argon shielding gas is the virtue of TIG welding for the thin metal sheet of mild steel and aluminum.
The versatile welding technique for both thin sheet and a thick section for high productivity where constant electrode wire is feed with shielding gas to make a strong weld is MIG welding. The process needs a power source, a wire feed system, and a MIG welding torch.
As the name suggested GMAW needs shielding gas to operate a MIG welding while gasless MIG welder is possible where a flux-cored wire supported on a tubular wire feeder is used. The flux changes to vapor a compound that protects oxidation at the weld pool. As the name suggests, GMAW requires gas shielding to conduct MIG welding while a gasless MIG welder is possible where a flux-core wire supported on a tubular wire feeder is used. The flux changes to vapor a compound that protects oxidation at the weld pool.
The welding of aluminum by MIG is a tricky process where the thickness of metal should be 14 gauge or more, clean surface, proper gas in combination, proper gun and spool and right filler material may be needed for MIG welding of aluminum metal.
The MIG and TIG welding processes require different conditions. MIG is a universal process that is used at a faster rate for thick metals while TIG welding can be used for thinner metals and for precision work.
