How to TIG Weld Stainless with Clean, Repeatable Results

If you’re searching for how to tig weld stainless, you don’t need hype—you need precise, repeatable steps. TIG Welding Secrets shows exactly how pros control heat, gas coverage, and filler to produce clean, code-worthy joints. Set amperage by thickness, sharpen and size 2% lanthanated tungsten for stable arc starts, match 308L/316L filler to the job, and pair a gas lens with a #8–12 cup for full coverage. Master purge setup to prevent sugaring, then dial travel speed and torch angle to minimize distortion and color.

Developed by welders who train aerospace, sanitary, and fabrication shops, this field-tested playbook replaces guesswork with clear procedures, photos, and setting ranges you can trust. It’s the no-nonsense answer to how to tig weld stainless with consistency.
