What are the different types of welding in the steel industry?

Coalescing materials like thermoplastics or metals so that they join them seamlessly is called welding. In this process, while joining two materials together, both pressure and heat are applied to them along with a filler material that creates a weld pool which gradually cools and forms a very strong joint.

Thanks to the evolution of technology, the welding process has evolved a lot over the years and it has led to various different techniques for welding. Before welding, one needs to choose the right process so that the best results can be achieved with maximum efficiency. Mentioned below are a few types of welding process that are used by the top steel manufacturers in India:

Flux Cored Arc Welding

This type of welding is similar to MIG welding. In Flux Cored Arc Welding a tubular wire is used that is filled with flux. Using shielding gas in this type of welding process is not mandatory. It depends on the type of filler that is used. For beginners, this process is apt as it is simple to learn and very affordable. Flux-cored arc welding is good for beginners, even though Despite the fact that the results of this welding process aren’t always aesthetically pleasing, this is quite widely used.

Submerged Arc Welding

Submerged arc welding is quite popular and mainly used on nickel-based and ferrous steel alloys. This is owing to its minimal fumes emissions. Also, this process requires minimal preparation and offers satisfactory results that make it efficient and quick.

TIG Welding

When a non-consumable gas such as argon is used to produce high quality, strong weld, the process is called Tungsten Inert Gas welding. In this process, electrical current is run through the tungsten electrode to produce heat. This technique is perfect for use in all kinds of applications and commonly used to weld stainless steel, copper, nickel, aluminum, and magnesium.

Electroslag Welding

To weld non-ferrous thick materials this single-pass efficient welding process is best suited. Contrary to the other processes, this is a complex technique that cannot be executed without a lot of skill. This technique is famous in the aerospace and maritime industries.

Gas Welding

This technique is quite different from other welding techniques that are used in modern days. Compared to the other techniques, this is a very old technique and also known as oxyacetylene welding. However, despite it being old, this technique is used to date in tube and pipe welding.

The largest steel producers in India use these welding techniques. They are very efficient and useful.
