Utilizing the Different Welding Processes for Large Metal Fabrication

Heavy metal fabrication has grown into a key industry, which incorporates various processes that alter metal plates into finished products. Fabrication of heavy metal can be structural, industrial, or commercial, depending on the needs of a company. The diverse requirements in producing metal products can demand complex procedures and complicated machinery, thus the need to work with qualified experts. Welding is one of the processes in heavy fabrication that allows the creation of joints and angles for easy connection of fixtures. The equipment standard and experience of a CNC machine shop determine the effectiveness of the welding services. Before finding a company to provide heavy fabrication welding, know what the process entails.

Before the welding process begins for a large fabrication in Ontario, the client must decide on the design of the components. If the shapes of the required metal parts are very specific, then the customer can present the necessary drawings. In the case of standard metal products, the machining shop can handle the drawings. The point is to ensure that welders have the correct shapes and sizes of the metal sections to guide the procedure. Several techniques are utilized in welding, and the suitability depends on many variables.

Different Welding Processes for Large Metal Fabrication

Tungsten Inert Gas Welding (TIG)

It may be a common method of welding, but it requires a high level of expertise from the welder, so you have to find a machine shop that has experts in this particular technique. The method uses a non-consumable tungsten electrode and an inert gas, usually argon, to protect the weld area from atmospheric contamination. It produces very high-quality products with an enhanced degree of purity, excellent finish, and a clean weld. Stainless steel may be the most frequent metal used in this welding process, but other materials have just as great results.

Submerged Arc Welding (ARC)

The safety of SAW is one reason it is preferred in large metal fabrication. It demands very little preparation of the surfaces, and the emission of welding fumes is minimal. The whole welding process occurs beneath a fusible flux, therefore, offering the welder protection from UV and IR radiation. It is most suitable for ferrous steel and nickel-based alloys.

Shielded Metal Arc Welding

Also called stick welding, this is the most popular of the joining processes, although some people may consider it a bit outdated. It uses a consumable electrode and is more manual than the other methods. The advantage of stick welding is that its cost is minimal, although the quality of work is not always the best.
