Welding in the Automotive Industry


Automotive industry have many situations where you require welding. There are many techniques that welders use in the automotive sector, like MIG, TIG or ARC welding. All of them have different purposes and benefits.

If welders have the basic welding knowledge, they choose a suitable technique according to the requirement. Make sure you use the proper safety precautions before starting work as a welder in the industry. The welding process temperature in automotive industries is high and creates a lot of harmful gases and fumes, ensure you wear safety gloves and eye-protective glasses, and have an appropriately sized welding fume extractor.

So here we will discuss the benefits of various technologies and the uses in the automotive industries. We asked a welding expert from Welding Superstore, an online shop with welding machines and the best welding helmets on the market and this is what we’ve heard.

Metal Inert Gas Welding (MIG)

MIG welding technique uses inert gas like argon and carbon dioxide for the automotive industry’s precise welding environment. This process is best suitable for beginners and doesn’t splash splutters too much, so it’s a clean process.

MIG welding continuously adds the metal fillers during the welding process. In this technique, we use the different gases according to the welding material like for stainless steel welding; helium gas is best. However, for straight steel welding, we use carbon dioxide and argon gas.

These gases act as the shield for the welded metal parts, so it also prevents the process of oxidation. MIG technique uses the consumable electrodes to join the metallic elements and induce electricity to them. So it is best for the automotive industries as it melts the weld pool through electrodes.

Make sure you properly clean the weld surface and also ensure the regulation of shielding gases. The MIG technique’s welding results are superb; that’s why many welders prefer to use it.

Arc welding

Arc welding uses the electrode, or you can say stick, as the main component. This technique uses the electric arc to join the two metal pieces. An electrode is mostly powered with the flux in the outer side.

It also prevents oxidation as the inner side of the electrode contains the metal filler. ARC welding temperature ranges to 3500˚C. But the only problem is that it leaves the powder from the flux that requires cleaning.

In the automotive industry, Arc welding is best for heavy metals like rusty materials. It has cability to penetrate inside the heavy metals quickly. However, using Arc welding makes sure that you use the appropriate welding rod suitable for the construction material. Arc welding is best for both AC and DC systems of the industry.

TIG welding

It has the tungsten rod connected with the handle of the welding torch and inert gas for the shield. Tungsten rod creates the electric arc that effectively melts the metallic parts and joins them at one point.

Welders love this technique because it doesn’t require any different material to conduct metal welding. The tungsten rod is also known as the non-consumable electrode that didn’t melt during the welding process. Also it doesn’t need any slag or flux, so produces clean welding. If you need to fill the space in metal, then you can use some filler rods.
