“When Tig Welding Stainless Steel: Tips for Success”
When Tig Welding Stainless Steel
Welding is an essential process for many industries, and for a lot of these, stainless steel is the material of choice. Tig welding stainless steel is the most popular and commonly used welding process for stainless steel, and for good reason. It is a reliable and versatile process that can be used to create many different shapes, sizes, and thicknesses of welds.
Tig welding stainless steel is different from other welding processes, like MIG and stick welding, in that it uses a non-consumable tungsten electrode to create the weld puddle. This makes it the perfect choice for welding thinner materials, as the process can be more precise and controllable.
Tig Welding on Stainless Steel
Tig welding on stainless steel is an extremely technical process that requires an experienced welder to be successful. The tungsten electrode needs to be precisely adjusted to the correct amperage and voltage for the job at hand. Additionally, the welder needs to be aware of the varying heat input capacities of different types of stainless steel, as this will affect the welding process.
The most important factor when tig welding on stainless steel is cleanliness. All surfaces need to be free from grease, oil, and any other foreign material before welding can begin. This is to ensure that the weld area is free from contamination and that the weld will be strong and reliable.
Tig Welding for Stainless Steel
Tig welding for stainless steel can be done with a variety of tungsten electrodes, depending on the type of weld you are trying to achieve. Pure tungsten electrodes are usually used for welding stainless steel that is less than 0.03 inches thick. Thoriated tungsten electrodes are best for thicker materials, and zirconiated electrodes are best for stainless steel that is over 0.03 inches thick.
It is also important to use a shielding gas that is compatible with your specific stainless steel. Argon is typically used for tig welding stainless steel, as it is an inert gas that creates a clean and reliable weld.
Tig Welding Stainless Steel Settings
One of the most important factors when tig welding stainless steel is setting the correct amperage and voltage. The amperage needs to be set to the correct level for the thickness of the material being welded, while the voltage needs to be set to the correct level for the type of stainless steel being welded.
For thin gauge stainless steel (0.03 inches or less), the amperage should be set to between 10 and 20 amps, while the voltage should be set to between 17 and 22 volts. For thicker materials, the amperage should be set to between 15 and 25 amps, while the voltage should be set to between 17 and 22 volts.
Conclusion
Tig welding stainless steel is a reliable and versatile process that requires an experienced welder to be successful. By following the tips and guidelines outlined above, you can ensure that your welds are strong and reliable. Remember to always use clean surfaces, the correct tungsten electrodes, and the correct amperage and voltage settings for the job at hand. With these tips, you can be sure that your tig welding stainless steel will be a success.
