When you're thinking about launching an industrial process that involves joining two different materials to form one, your mind should automatically turn to welding. Yet if you're not very familiar with the available solutions, you may be confused when it comes to the difference between MIG and TIG welding. On the face of it, these two approaches may seem similar, but there are distinct differences, and it pays to understand what they are before you make your choice. So, what do you need to know?

MIG Welding

MIG stands for "metal inert gas," and features an automatic arc that uses a consumable wire electrode to create the weld. The gas protects the weld and helps it to penetrate the metal to achieve the desired result. Both the electrode that creates the arc and the inert gas are fed through the welding gun. The electrode is made from a continuous wire consumed during the process. The type of wire electrode (in terms of its diameter and composition) will vary according to the category of metal and its size.

TIG Welding

Conversely, TIG (tungsten inert gas) features an entirely different type of electrode. Once again, the process will create an arc, but in this situation, the electrode is non-consumable and made from tungsten. In addition, there is a separate filler material in the form of a rod that will be manually fed into the welding pool. This requires some additional dexterity from the technician, who has to handle both the filler rod and the tungsten electrode. Again, the size and composition of the filler rod will vary based on the type of weld in question, and it is possible to adjust the heat during the welding process to give an extra element of control.

With such similarity, what are the advantages and disadvantages of each process?

MIG - Advantages and Disadvantages

On the plus side, MIG welding is the fastest of the two. This means you can create more welds in a shorter amount of time, contributing to a potentially lower cost. In addition, the process is easier to handle and requires less cleanup at the end. Still, MIG welds may not be as strong or as precise.

TIG - Pluses and Minuses

Many people think TIG welding is a far more versatile technique that can be used on smaller and thinner materials. Still, it's slower than MIG, increasing production times and potential costs. In addition, you will need technicians who are well-trained in this process in search of accuracy and precision, but these welds tend to be stronger and perhaps more aesthetically pleasing than MIG.
