TIG Weld Stainless Steel Like a PRO!

sstubeStainless steel is a steel alloy that contains chromium–which gives the metal that shine that it is prized for.  Also, stainless steel does not rust or corrode as easily as carbon steel, another property which makes it a popular metal for many TIG welding applications from industrial equipment, food processing, aerospace, and automotive.

Stainless can be tricky to weld, but as with most TIG Welding applications, a lot of practice, attention to details and procedure, will have you welding like a pro in no time.

How to TIG weld stainless steel

First, you’ll want to watch your heat.  Basic rule of thumb is that you’ll need 1 amp of welding current for every thousandth of an inch of material thickness.  You’ll also want to keep your weld speed up, and maintain good gas coverage.

TIG TorchYou’ll hear us repeat this often:  use a gas lens!  The gas lens collet body replaces the standard collet body in your TIG torch. It is comprised of a series of layered screens engineered to distribute the gas (generally argon) over the weld zone in a more coherent fashion for better coverage with less turbulence.    It is one of the best ways to get the most out of your TIG welding torch, and why we install gas lenses on our PRO TIG torch packages.

    I really appreciate the link to the Pro Kits.



    This is a great resource. Definitely a keeper for the welding archive.
    Thank you very much.

    Thanks for the information! I’ve done a bit of welding in the day, but I’ve never welded stainless steel before. One of my buddies told me that welding stainless steel is a bit of a different process than with other metals. I’ll be sure to take your advice and watch my heat and use a gas lens.

    I am a tig welder and it comes down to experience and practice. The more you do the better you get. Been doing SS and Ali for 25+ years so I’m getting the hang of it lol.
