MIG Welding Vs. TIG Welding both offered by Zechin Industries

There are various metal processing projects that require welding parts. We understand that welding is a crucial aspect of the manufacturing process, but because there are many different methods, it may be difficult to understand the differences or determine which method is best.

Many people ask: "What is the difference between MIG and TIG welding?" These two processes do have some things in common. Both processes use electric arcs to generate heat and connect metal objects, and both processes use an inert gas mixture to prevent corrosion of the welding electrodes. Whether you are unfamiliar or just need a quick look, please read on to understand the difference between MIG welding and TIG welding.

How Does Each Process Work?

MIG (also commonly referred to as metal inert gas) is a process in which metal wires are continuously fed into the weld to be formed. Essentially, the wire acts as a filler material to help connect two metal objects together. On the other hand, TIG welding or tungsten inert gas arc welding incorporates a non-consumable tungsten electrode that allows current to flow through the metals being joined. Depending on the project, TIG welding may or may not use filler metal.

In MIG and TIG welding, the molten pool is protected from the atmosphere by the inert gas shielding gas surrounding the arc. Although these two welding techniques have their own advantages, they cannot replace one of them. They are not interchangeable and are used for their specific purpose. MIG is ideal for large projects, while TIG welding is very suitable for small projects, including the use of foreign metals such as gold, nickel and brass

What Makes Each Process Unique?

The continuous feed used in MIG welding helps reduce the possibility of welding defects that may occur during pauses and intervals. Compared with TIG welding, this process is very easy because the welding wire will be unwound from the spool and fed into the welding pool for filling purposes.

TIG is suitable for welding ferrous metals and non-ferrous metals with a thickness of no more than 8mm. Since this process is slow, the end result can produce high-quality welds with perfect clarity in aluminum, carbon steel and stainless steel. When particularly high-quality welding is required, TIG welding is a super choice.

Which Process Requires More Experience to Use?

If you are looking for a solution based on ease of use, MIG welding is more suitable. Considering that TIG welding requires precise control of the time, pressure and current in the weld, MIG welding is more tolerant of errors than TIG welding.

Which Process Is Better Suited for Welding Thicker Metals?

Generally, MIG welding is the best choice for heavy duty welding. For thinner metal sheets, we recommend that TIG welding is a more effective choice. This is why. As we mentioned earlier, MIG welding uses filler materials for welding, and it is usually helpful to complete thicker metal welding in a shorter time than TIG welding.

Since TIG welding does not use filler material, the metal sheet to be welded must be hot enough to form a bond, which is why it is easier to use TIG welding for thinner metal sheets.
