What’s The Difference Between Mig And Tig Welding?

Here’s a concern that a lot of individuals ask: What’s the difference between MIG and TIG welding?

A little confusion is perfectly typical. After all, both processes use electrical arcs to produce heat and join metal objects. Likewise, both procedures use an inert gas mix to prevent rust of welding electrode.

But, there are some essential differences in between these 2 electrical arc welding procedures:

How Each Process Works

MIG, or metal inert gas, welding is a process that involves continually feeding a metal wire into the weld being made. The wire serves as a filler material to assist sign up with the two metal objects.

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

Suitability for Welding Thicker Metal Things

Since MIG welding uses a consumable filler material to make welds, it can frequently 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 easier with thinner pieces of metal than with thicker ones.

Overall, for truly thick, durable welds, MIG welding is the go-to choice. For thinner pieces of metal, TIG welding has the tendency to be the more reliable option.

Ease of Control

Normally speaking, MIG welding is more often suggested for ease of use. The process has the tendency to be a bit more forgiving of mistakes than TIG welding is– so it’s typically recommended for newbie operators and non-professionals.

TIG welding, on the other hand, requires extremely rigorous control over the timing, pressure, and electric present used in the weld. TIG welding is best done utilising an automated, computer numerically-controlled (CNC) welding machine. Devices can dependably perform identical welds over and over a lot more quickly than a manual welder could.

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

Which One is Better?

The response depends on the job in question. As kept in mind previously, MIG welding is generally better for heavy-duty welding work where bigger, thicker pieces of metal are being joined since it uses filler material.

TIG welding can work wonders for signing up with smaller sized pieces of metal, such as the wires for a customised steel wire basket. Because the TIG process straight joins 2 pieces of metal, there’s no filler material to fail.

With robotic welding devices, TIG welding can be a bit lower-maintenance, considering that the welding electrode isn’t being constantly consumed by the welding procedure. Nevertheless, the welding electrode still has to be correctly cleaned and polished in between uses– especially when welding stainless steel.

Simply put, choosing one welding service as the very best need to be done on a case-by-case basis, which is why Marlin Steel is devoted to having a variety of tools and technologies for completing welds.
