| Hi, When compared to FCAW and MIG, MIG is better than FCAW. because GMAW can give excellent results. The finished weld has no slag and almost no spatter. If the material you're welding is dirty, rusty, or painted, you must clean it properly by grinding until you get shiny surface/bare metal. GMAW successfully with common commercial metals — low-carbon steel, low-alloy steel, stainless steel, and aluminum. better for root pass. FCAW - more welding operator/welder control required,proper selection of electrode diameter related to thickness etc.,,if welder is not capable- poor bead,more spatter,incomplete penetration and FCAW mostly suits for thicker materials.some times can with thinner material with lesser dia of electrode. but finishing/quality GMAW is better than FCAW.
