Is MIG Welding Good for Car Body Restoration?

Many of us like old cars and want to restore them. The entire car restoration project needs very good bodywork.

Without a good welder, this kind of restoration project will turn into a nightmare. But you just cannot use any kind of welder for the car body.

Types of Welding Procedures Used in the Automotive Industry

There are four kinds of welding procedures in the market. They are gas welding, stick welding, TIG (Tungsten inert gas) welding, and MIG (Metal inert gas) welding.

So, which one to use for the car body?

Before choosing the right kinds of welding techniques for your work, you need to understand the design of the body well.

A car body is made of thin metal. And the type of metal you are going to use for car body redesign is also some kind of thin metal sheet.

So, you have to choose wisely. A lot of people are comfortable with using gas and stick welding. Both of them are conventional and old. Yet they are very effective for car bodies.

TIG and MIG are quite new to compare. However, these are getting popularity among the restoration workers.

But, which one you need?

Best Welding Method for Car Body Works

We prefer both Stick and MIG. Commonly the MIG, TIG, and Stick are used in automobile restoration. But at the moment MIG welding is the most popular one and choosing the right MIG welder is crucial.

For car body, we do butt, lap, and off sheet lap joint, and the MIG welding method is the best one for this type of joint.

Hence, I suggest you use the MIG, and here are full details of it.

How MIG Welding Works?

One piece of wire contacts and makes a direct short circuit. This short circuit creates heat and makes the wire meltdown. This is how a puddle of melt metal is made for joining two parts.

You have to continuously feed a wire in this process. This whole process is easy to handle. It can be easily re-established with more added wire.

But to become a master welder with MIG is a bit of a challenge. You need to find out the right amount of gas follow for every different work.

There are two regulators to control the gas follow. You need to set both of them in the right position. In short, you need to synchronize both of the regulators.

Improper use of gas follow can destroy your work and hamper it. You can work with .023 to .025 inch wire and 10 to 20 CFM which are good enough for car body works.

But why the MIG is so much popular even after these difficulties? The answer is normal; it is way easier to use and has some other benefits too.


The MIG produces 15 percent less Co2. The other entire welding needs 220V for properly working where MIG can run in household 110V. It is in any way portable and can be used anywhere.

Some people say MIG is not for thick metal. But in our experience, MIG will cut through any car body and enough for working with thick metal. The types of joints we normally use for car body can easily be done by it.

Frequently Asked Questions about MIG Welding & Auto Restoration

These are the right question for you to choose the right kind of welding machine.

What Kind of Metal Can Be Welded?

Cars normally made of steel. Some of the sports car bodies are made of aluminum. However, MIG welding works in both steel and aluminum. But, special caution is required to weld aluminum.

How Much Electricity is Needed?

Most of the MIG welding machines work in 110V and they don’t need many watts. Your home electric line will be good enough to do most of the works. Some of the devices need 220V though.

What is the Maximum Cutting Capacity of MIG Welding?

A standard device can cut up to 0.25inch which is good enough to cut the car body metals.

How Much Welding Overhead You Need to Use?

Not a single one.

What Types of Joint Can You Make?

On the body of the car, we use the butt joint, lap joint, and off sheet lap joint. There are other kinds of joints but we hardly use those. These major joints can be done perfectly with MIG machines.
