Tig Weld thin Stainless Steel  

Tig welding thin stainless steel can be tricky due to its heat sensitivity and tendency to warp easily. But with the right know-how, you can master this welding technique to create clean and precise welds. This guide will teach you the basics of tig welding thin stainless steel so you can confidently tackle your next project.

What is TIG Welding?

Tig welding is a type of welding that uses an arc created between a non-consumable tungsten electrode and the base metal. It’s often used for applications where precision is key as it offers more control over the weld than other types of welding, such as Mig or Stick welding. This makes it ideal for projects requiring tight tolerances, such as working with thin stainless steel.

Weld Prep & Settings

Before getting started on your tig weld, it’s essential to properly prepare the material and adjust the settings on your welder. For thin stainless steel, use a low amperage setting – typically in the range of 10-20 amps – and a gas lens cup to better direct shielding gas flow around your workpiece. Additionally, clean any dirt or debris from the surface before beginning your weld; this will help ensure that you get a clean finish without any contamination in your weld bead.

Welding Technique

Once everything is prepped, you can begin welding! Start by striking an arc at one end of your workpiece while slowly pushing forward along one side of your joint, maintaining a consistent speed and distance from the material as you go. As you progress along your joint line, gently move up and down on either side of your joint line to create a full penetration weld. Be sure not to push too hard against the material or stay in one spot for too long; these things could cause warping due to excessive heat buildup in one area! When finished, let cool completely before handling.


With proper preparation and practice, tig welding thin stainless steel doesn’t have to be intimidating! By following these steps and adjusting settings accordingly, you can create strong, beautiful welds with ease – even if this is your first time tackling this particular skill! We hope this guide has given you everything you need to get started on your next project successfully – happy welding!
