Tig welding what is the difference between mig and

TIG welding is a process which requires a constant current power source and uses a non-consumable tungsten electrode to run a current through both metals and join them.

It is a clean, versatile process and requires the most skill for a welder. While MIG welding and TIG welding are both processes that create a weld using an electric arc, the techniques used to achieve that arc are quite different. MIG welding uses a continuous wire feed to create a spark and form the weld. Whereas, TIG welding uses non-consumable tungsten welding rods to generate extreme heat which then melts the metal and creates a weld.

However, it also offers greater control during the welding operation and produces strong, precise, and aesthetically pleasing welds. It employs a consumable wire that acts as both the electrode and the filler material. Compared to TIG welding, it is much faster, resulting in shorter lead times and lower production costs. Additionally, it is easier to learn and produces welds that require little to no cleaning and finishing.

However, its welds are not as precise, strong, or clean as those formed by TIG welding operations. Typical weld materials include aluminum, carbon steel, and stainless steel.

Similarities between MIG and TIG welding Both the TIG and MIG welding are basically arc welding processes as electric arc is constituted between the electrode and the base plates to melt down the faying surfaces and to form the coalescence. They also come under fusion welding processes as base metals are fused during joining. Both the processes utilize bare electrode.

Although the electrode material is different in these two processes, but no flux-coated electrode is employed in any of these two processes. In both the cases, shielding gas is required to supply from additional sources. This is unlike MMAW or FCAW process where shielding gas is inherently obtained during the process due to the disintegration of the flux available with the electrode.

Inert shielding gas is used in both the cases to protect hot weld bead from oxidation and contamination. Only inert gases like argon, helium, nitrogen, or a mixture of such gases are employed for shielding purpose. Only conductive metals can be joined by these two processes. In fact, all arc welding processes are applicable to conductive metals only.

Solid state welding can be applied for joining non-conductive metals. Tungsten inert gas TIG welding utilizes a non-consumable electrode so it remains static and intact during welding. The electrode itself melts down to supply necessary filler metal required to fill the root gap between base metals. So electrode acts as filler metal no additional filler is required. If required, filler metal is supplied additionally by feeding a small diameter filler rod into the arc.

So filler metal is supplied separately. Composition of electrode metal is selected based on parent metal. Usually, metallurgical composition of electrode metal is similar to that of base metal.
