What’s The Distinction Between Mig And Tig Welding?

Here’s a question that a lot of individuals ask: What’s the distinction in between MIG and TIG welding?

A little confusion is perfectly normal. Both processes utilise electrical arcs to produce heat and sign up with metal objects. Likewise, both procedures use an inert gas mixture to prevent corrosion of welding electrode.

There are some essential distinctions between these two electrical arc welding processes:

How Each Process Works

MIG, or metal inert gas, welding is a process that includes continuously feeding a metal wire into the weld being made. The wire acts as a filler product to help sign up with the two metal items.

TIG, or tungsten inert gas, welding uses a non-consumable tungsten electrode to run a current through the metals being joined and might or may not utilise a filler metal.

Suitability for Welding Thicker Metal Objects

Because MIG welding employs a consumable filler material to make welds, it can often complete welds of thicker metal things in less time than a TIG weld.

Without a filler material, TIG welding has to get the pieces of metal being welded hot enough to form a bond with each other. Normally, this is simpler with thinner pieces of metal than with thicker ones.

In general, for actually thick, heavy-duty welds, MIG welding is the go-to choice. For thinner pieces of metal, TIG welding tends to be the more efficient service.

Ease of Control

Typically speaking, MIG welding is more frequently recommended for ease of use. The procedure has the tendency to be a bit more flexible of errors than TIG welding is– so it’s typically recommended for first-time operators and non-professionals.

TIG welding, on the other hand, needs extremely stringent control over the timing, pressure, and electrical present utilised in the weld. In most cases, TIG welding is best done utilising an automated, computer system numerically-controlled (CNC) welding machine. Devices can dependably perform similar welds over and over much more quickly than a manual welder could.

When using an automated welder (whether it’s MIG or TIG), it is essential to get the weld settings and controls perfect– otherwise, you risk duplicating the same mistake over and over.

Which One is Better?

The response depends on the job in question. As noted previously, MIG welding is usually better for heavy-duty welding work where larger, thicker pieces of metal are being joined due to the fact that it uses filler product.

TIG welding can work marvels for joining smaller sized pieces of metal, such as the wires for a custom-made steel wire basket. Due to the fact that the TIG procedure straight joins 2 pieces of metal, there’s no filler material to stop working.

With robotic welding devices, TIG welding can be a bit lower-maintenance, given that the welding electrode isn’t really being continuously taken in by the welding process. Nevertheless, the welding electrode still needs to be properly cleaned up and polished between uses– particularly when welding stainless-steel.

Simply put, choosing one welding solution as the best need to be done on a case-by-case basis, which is why Marlin Steel is dedicated to having a series of tools and technologies for finishing welds.
