Metalwork is an important part of the manufacturing and construction industries. To maintain quality production, businesses in these industries get the services of welding companies like Advantage Manufacturing Ltd. in Edmonton, which offer welding services that strictly follow industry standards and are best for wide-scale construction projects.
These companies are also best if you have custom manufacturing needs. If you require a particular piece of equipment following your own specifications, for instance, these welding service providers can give you the best quality products with the shortest manufacturing time.
The Welding Process
Welding is not about just fusing together pieces of metal like steel or aluminum. The more important part of the process is ensuring that the weld holds these pieces together well and that it is not susceptible to corrosion.
When an electric arc is passed through the weld, it causes high heat, which practically melts the welding stick into the joint. However, the same heat also introduces impurities in the weld. Impure metals are usually brittle, and this may mean that the weld is not secure. It can cause a weak weld, leading to a loose joint.
Different methods are incorporated into the welding process to ensure the purity of the weld. In most instances, an inert gas is part of the process. Inert gases like argon and helium are used to protect the welding process from atmospheric contamination.
Types of Welding Services
Shielded Metal Arc Welding (SMAW) is a common welding service, wherein the heat of the arc melts the welding stick as well as the parts that are to be welded. The process includes the release of a gas vapor, which seals the weld and metal joints. Gas Tungsten Arc Welding (GTAW), meanwhile, uses argon or helium to protect the welding process.
Gas Metal Arc Welding (GMAW) is the most common welding method in industrial manufacturing due to its versatility. It uses argon and carbon dioxide to protect the weld from contamination. Flux-Cored Arc Welding (FCAW) uses a tubular wire filled with flux, which protects the metal during welding. Shielding gas may also be used in the process. Submerged Arc Welding (SAW) uses granular flux, which creates a blanket that completely submerges the welding area, protecting it.
