An Overview of MIG Welding in Sheet Metal Fabrication

26 March 2021

Metal Inert Gas (MIG) welding offers various advantages for efficiency without giving up nature of the completed weld, however there are numerous elements that can meddle with fruitful MIG welding execution. You can improve execution and results in your MIG welding applications — and set aside cash through diminished consumable waste — by finding a way to maintain a strategic distance from normal errors identified with the MIG weld and consumables. Dodging regular errors encourages you get the best outcomes in MIG welding. It’s likewise critical to appropriately keep up the MIG machinery and consumables, so it is best to know what can go wrong in MIG welding.

Known also as GMAW (Gas Metal Arc) welding, this technique uses a special inert shielding gas to protect the weld pool. Considered the group “all-rounder,” MIG welders can join thin and thick metals. The equipment used to do this comes with a number of adjustable electrode settings, so the gear is easier to master. Well, it is as long as the welder is familiar with all of the power settings. If we were to list any application drawbacks, it would be the fact that it lacks power, accuracy, and MIG can only be used in a handful of welding positions.

Metal inert gas welding, using its shielding gas and wire-feed electrode, is believed to be one of the easiest welding techniques to learn. That’s an immediate advantage. Expect hobbyists and motorsport enthusiasts to own a MIG rig. Stored in their garages, the equipment is pulled out everytime a big weekend project comes around.

MIG Welding: Why is it Beneficial in Sheet Metal Fabrication

Some experts say they can teach a student how to use MIG welding equipment in under an hour. That may be true for a weekend warrior, but experts require years of training to get the most out of their tools. Still, that’s a notable benefit. The training is carried out, the welder becomes familiar with the equipment, certifications are issued, and another welder enters the field. Of note, there’s still a need to clean the weld site. Next on the list, then, because of the wire feed system,

Metal Inert Gas work is fast. There’s no pausing to grab more consumable materials, more welding rods, no stopping to clean away slag. When the welder gets going, a streamlined workflow comes naturally. MIG welding is a slag-less welding method. The shield gas stops atmospheric reactance and it features feed-wire efficiency, produces clean, uninterrupted welds, and is suitable for thinner sheet metals.
