SMAW and GMAW differ in how they shield the molten electrode from atmospheric gases. SMAW encases the electrode in a layer of material known as flux. For this reason, GMAW also goes by the name of metal inert gas welding, or MIG welding.Oct 5, 2018
What is difference between GTAW and GMAW?
GMAW utilizes a consumable electrode. So electrode material melts down and deposits on weld bead. GTAW or TIG welding uses non-consumable electrode and thus electrode material is not deposited on weld bead. GMAW process is much faster as electrode (or filler) is continuously fed by mechanized system.
What is SMAW students?

Why is it called SMAW?
SMAW Arc Welding Stick welding takes its' name from the shape of the electrode, which looks like a stick. It can be used to weld many types of metals including steel, stainless steel and cast iron.
What is SMAW GMAW and GTAW?
SMAW—Flux coating of electrode disintegrates during welding and produces shielding gas. No separate shielding gas is applied separately. GMAW—Shielding gas (inert or active) is supplies from gas cylinder. GTAW—Inert shielding gas is supplied from gas cylinder.Oct 2, 2018
