![]() ![]() Both are substantially more expensive and less portable than TIG. The only other welding processes that come close to the strength and quality of TIG welding is Plasma Arc Welding (PAW), really a type of ultra high heat arc welding that converts the shielding gas to plasma, and laser welding. If it does come down to only choosing one arc welding process, then TIG is going to be the one to choose. When it comes to MIG vs TIG vs Flux core, it is often a matter of choosing which two to use rather than choosing any single one. If one was forced to weld in the midst of a hurricane, Flux core would be the process to use if options were provided. However, it is an extraordinarily fast welding process, incredibly portable, and can produce acceptable welds in poor environments. Properly performed MIG welds are objectively of metallurgically higher quality than equivalent FCAW due to the gas shielding. This results in a structurally strong weld, but one that is more mixed than either TIG or MIG welds. When the arc is struck, the flux melts along with the metal, bonds with any impurities and floats to the surface of the weld where it protects the weld from further intrusion. However, it depends on a core of flux in filler wire to create a pure metal weld. However, at the structural and molecular level they are substantially different.įlux core is a wire feed welding process like MIG. The equipment looks almost identical save for the fact that FCAW does not require shielding gas and lacks the appropriate fittings. MIG and Flux core are so similar from the operators standpoint that many welders refer to FCAW as MIG welding reflexively. MIG vs Flux Core: Choosing a Wire Feed Winner This means the root pass will need to be TIG welded while the rest of the sidewall thickness can be filled with MIG or FCAW, saving substantial amounts of time on the project overall. In more forgiving welding applications, like in the petrochemical industry, the quality of TIG welding is really only needed to resist the corrosive properties of the petrochemical products in the line. When sanitary welding standards for pharmaceuticals or biopharma need to be met- welding food grade stainless steel pipe for example-the entire depth of the weld should be welded with TIG. The overall comparison of MIG vs TIG vs Flux core suggests that TIG should be used when quality of the weld is primary consideration. A general comparison of the MIG vs TIG vs Flux core welding can be seen in the following table: MIG vs TIG vs Flux Core They are also wire fed processes that are very easy to use and incredibly portable. Filling in that same sidewall thickness with MIG or FCAW will take minutes to an hour instead of several hours. MIG and Flux core welding have the advantages of being much quicker. If you need to weld a pipe to a fixed installation in an outdoor environment, then a tent might need to be erected. ![]() Wind can blow away the shielding gas and ruin a TIG weld. The process is also not very portable and is sensitive to changes in the air. Filling in a thick pipe sidewall using only narrow gap welding is time consuming on the order of several hours, at least. However, even with the reliability that comes from orbital welding, the process is still very slow. Only by automating the process could the full potential of TIG be realized repeatedly and reliably. The problems in producing welds that lived up to the full potential of the TIG process is what led to the invention of orbital welding in the first place. However, quality is not the only consideration. If the only consideration was the strength and quality of the weld bead resulting from welding, then TIG would win every time. MIG vs TIG vs Flux Core Compared Head to Head They find their best use in different parts of orbital welding, and all three may be combined to complete a single orbital weld in big bore pipe welding and other large diameter pipe welding. When it comes to MIG vs TIG vs Flux Core, they all have different advantages and disadvantages. Tungsten Inert Gas Welding (TIG), also known as Gas Tungsten Arc Welding (GTAW), is difficult to master but produces welds of exquisite quality and exceptional purity.Īll three arc welding methods have been adapted to orbital welding. Wire Fed Flux Core Arc Welding (FCAW) and Metal Inert Gas (MIG), or Gas Metal Arc Welding (GMAW), produce completed welds so swiftly that it seems almost magical. There are three arc welding processes that provide nearly miraculous seeming results. ![]()
