The welding process of stainless steel relies upon the usage and the thickness of the element. Though there are various processes available to weld stainless steel, the main three most popular processes include resistance welding, TIG welding and MIG welding which are used in the United States. Stay with us to the end of this article to know details about the structural steel fabrication process.
What Is Stainless Steel?
It is a combination of carbon, iron and 10.5% chromium. It is a very popular material among people due to its corrosion resistance power and strength. The experts can differentiate the quality of stainless steel by determining their combination of other elements.
- MIG Welding
MIG welding is also known as Gas Metal Arc Welding. In this process, the experts use electricity to melt and join the metal pieces together. This process requires a wire so that it can be connected with a direct current. The source of the direct current acts as an electrode for joining the pieces. Keep in mind that the shielding gas mix for the MIG welding process is a combination of 7.5% argon, 90% helium and 2.5% carbon dioxide. The specialists can produce long weld lines very fast.
- Gas Tungsten Arc Welding
We also call this process TIG Welding in general terms. It is one of the most common welding processes of stainless steel. It produces versatile, durable and high-quality steel. This process is pursued by creating a low heat input. For this reason, this type of system is appropriate for thin materials.
The experts mist the argon gases for other gases such as hydrogen, nitrogen and helium-based on the needs of the specific project. Using a single-sided welding process is far better for creating inert backing gas protection between the exterior and interior welds. This process helps to increase resistance power and prevent oxidation.
- Resistance Welding
This process is used for seam and spot welding. Experts send the electrical current through an electrode and after coming into contact with the metal, a nugget and resistance heat are produced. Not to mention, this process generally has to operate in low voltage to create the spot welding.
Resistance welding is very effective compared to other types of welding. If you use this type of welded steel, you may need low heat concentration and heating time. As it is automated and mechanized, therefore, the welders do not require long hours of pre-service training. You can get long lasting, aesthetic welded steel at a very reasonable price.
