3 Famous Methods for Welding Stainless Steel

Business

A stainless-steel welding process greatly depends upon the finish, thickness and the final use of the completed product. While there are numerous procedures available to weld stainless steel, however, the following three are the most widely used ones.

  1. Gas Tungsten Arc Welding (TIG): TIG is undoubtedly the most popularly used stainless steel welding procedure that offers high-quality strength as well as versatility to the welded metal.

Stainless welding machine (เครื่อง เชื่อม แตน เล , term in Thai) offers aLow heat input, which makes it ideal for the thinner metals. Based on project needs, argon gas is often mixed with helium, hydrogen and nitrogen to prevent oxidation and impart strong resistance against metal corrosion.

A single-sided welding process can be used to generate an inert gas shield between the exterior and interior welds.

  1. Spot Welding: Spot welding often referred to as resistance welding is one of the most economical welding processes available. The specialized resistance welding equipment is amazingly versatile and hence, it can be used in both small and big projects with equal ease.

Resistance welding device makes use of electric current to heat the metal edges and then bind them together. This type of welding is especially helpful in the case of metals which have a considerably low melting point- With RW you have the provision to customize the amount of power supplied, thus preventing the metal distortion in the process.

  1. MIG welding: Metal Inert Gas (MIG) welding is a semi-automated procedure which if managed correctly could join two stainless steel metals with great precision and impart appreciable binding strength. Argon is used as the shielding gas while a solid wire acts as an electrode here.

MIG is widely used in the steel welding projects since it allows the welding professional to make use of pulsed current supply- The process makes it easier to weld difficult-to-reach spots, which was earlier a common problem faced during the execution of highly intricate stainless steel welding projects.

Apart from this, different gas mixtures, which may include helium, carbon dioxide, oxygen etc., are frequently used to impart stability to the arc and also to improve the overall quality of the weld.

The choice of a welding machine (เครื่อง อ๊ อก เหล็ก, which is a term in Thai) largely depends upon your requirement and the metal type. In case you are looking for an economical option, spot welding is best suitable for you. However, in case you need to work with the thin metals, then you might have side with TIG. Hence, study your requirements well to pick the best method for the job.
