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

A little confusion is completely normal. After all, both procedures use electrical arcs to produce heat and sign up with metallic things. Both procedures use an inert gas mixture to prevent rust of welding electrode.

There are some essential distinctions in between these 2 electrical arc welding processes:

How Each Process Functions

MIG, or metal inert gas, welding is a procedure that involves continuously feeding a metal wire into the weld being made. The wire acts as a filler product to assist sign up with the two metal objects.

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

Viability for Welding Thicker Metal Things

Due to the fact that MIG welding utilises a consumable filler product to make welds, it can typically complete welds of thicker metal things in less time than a TIG weld.

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

In general, for actually thick, durable welds, MIG welding is the go-to option. For thinner pieces of metal, TIG welding has the tendency to be the more efficient service.

Ease of Control

Usually speaking, MIG welding is regularly suggested for ease of use. The procedure tends to be a bit more flexible of errors than TIG welding is– so it’s often suggested for newbie operators and non-professionals.

TIG welding, on the other hand, needs very stringent control over the timing, pressure, and electrical present utilised in the weld. TIG welding is best done utilising an automated, computer numerically-controlled (CNC) welding device. Makers can reliably carry out identical welds over and over much more easily than a manual welder could.

When utilising an automated welder (whether it’s MIG or TIG), it’s important to obtain the weld settings and controls just right– otherwise, you run the risk of repeating the exact same error over and over.

Which One is Better?

The response depends upon the job in question. As kept in mind earlier, MIG welding is normally better for sturdy welding work where bigger, thicker pieces of metal are being joined due to the fact that it utilises filler material.

Nevertheless, 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 two pieces of metal, there’s no filler product to stop working.

With robotic welding equipment, TIG welding can be a bit lower-maintenance, since the welding electrode isn’t really being continuously taken in by the welding process. The welding electrode still needs to be appropriately cleaned and polished between uses specifically when welding stainless steel.

In short, choosing one welding option as the best need to be done on a case-by-case basis, which is why Marlin Steel is dedicated to having a range of tools and innovations for completing welds.
