Although they may appear similar, MIG and TIG welding are different in a number of ways, with each offering a few key advantages over the other. Depending on the nature of your project, you may choose one welding technique over the other based on a few important factors, such as the need for precision, the length of your welds, and whether the finished welds will be visible.
MIG vs TIG Welding
At their core, both MIG and TIG welding are highly versatile processes used to join metals. With both methods used in a variety of industries, including manufacturing, automotive, construction, and aviation, both processes utilize an electric arc and a shielding gas to do the work. However, there are several crucial differences that distinguish one welding method from the other.
MIG Welding Process
Also known as gas metal arc welding, MIG welding allows for much faster welding speeds than TIG welding. It uses a welding gun and a one-time consumable wire electrode that is melted by an electric arc, resulting in clean, consistent welds. But, MIG welders often struggle with thinner materials, as the process is best suited for thicker metals.
TIG Welding Process
Because it uses a tungsten electrode, TIG welding is often called gas tungsten arc welding. Like the MIG process, TIG uses an electrode to create an electric arc. However, unlike MIG welding, the electrode used in TIG welding is a non-consumable tungsten electrode. Considered to be far more difficult than MIG welding, TIG welding offers higher precision, visibility, and coordination. But, it does yield cleaner, more reliable welds. It’s also better suited to thin materials and various metal types.
What do experienced welders prefer?
Sadly, there’s no easy answer to this question, as it largely depends on the application. When it comes to speed, it’s often best to opt for MIG welding, which is a great choice for fast production schedules. But, most TIG welders swear by the improved control, quality, and versatility that TIG welding produces.
So, before your welding project starts, you’ll want to ask a few questions, then consult with your team:
- Is fast production speed a necessity?
- What level of weld strength do you need?
- Are you welding thinner or thicker materials?
- Are you welding sheet metal, cast iron, or mild steel?
- Are aesthetically pleasing welds required?
