Differences between MIG and TIG welding MIG Welding TIG Welding Metal inert gas (MIG) welding utilizes a consumable electrode that is continuously fed into the welding zone from a wire pool. Flux-core welding does not need a high skill level . That being said, there are still some situations in which an oxyacetylene torch is just as goodor even Gas Welding. The resultant arc temperature is around 6000C whereas gas welding produces only around 3600C. An ideal weld or good weld must be one that exists with good penetration with sufficient fusion between the filler metal and the edge preparation. It provides design flexibility. Gas welding is accomplished by melting the edges or surfaces to be joined by gas flame and allowing the molten metal to flow together, thus forming a solid continuous joint upon cooling. Arc welding VS.
