The most common stainless steel welding methods
The process by which stainless steel is welded varies depending on the thickness and finish of the material, as well as the use of the finished product. While there are a variety of welding methods used for stainless steel, there are three that are used most commonly by welders in the United States. They are TIG welding, resistance welding, and MIG welding. Keep reading to learn more about each.
TIG WELDING OR GAS TUNGSTEN ARC WELDING
Offering high quality, versatility, and longevity, TIG is the most commonly used welding process. This welding process creates a low heat input, which makes it perfect for thin material. The argon gas is often mixed with other gases, depending on the needs of the specific project, including helium, hydrogen, and nitrogen. To prevent oxidation and increase resistance to corrosion, a single-sided welding process can be used creating inert backing gas protection between the interior and exterior welds.
RESISTANCE OR SPOT WELDING
Resistance or “Spot” welding, as it is often called, is one of the most economical types of welding. The resistance welding (RW) equipment is incredibly versatile, which means it can be used on both small and large projects.
RW uses an electrical current to heat frayed metal edges and seal them together. This type of welding is exceptionally productive on metal with low melting point because it can be tailored to prevent distortion of the metal.
MIG WELDING OR GAS METAL AC WELDING
MIG welding is a semi-automatic process that when done correctly offers a strong joining of two pieces of stainless steel. This process uses an argon rich shielding gas and a solid wire electrode.
MIG welding is popular because it allows the welder to utilize a pulsed current supply, which can make it easier to weld those tough-to-reach spots on complex stainless steel projects. Other gases mixtures, including those with helium, oxygen, and carbon dioxide, are often used to stabilize the arc and improve the quality of the weld.
WHICH STAINLESS STEEL WELDING METHOD IS BEST?
Choosing the right stainless steel welding method for your project really depends on what qualities you’re looking for. If you’re looking for a more affordable weld, spot welding might be the best option for the job. But if the material we’re working with is thin, then TIG or gas tungsten arc welding might be the better choice.
