How to TIG Stainless Steel without Warping, Sugaring, or Discoloration

Stainless punishes guesswork. To master how to TIG stainless steel, you need tight prep, clean gas coverage, precise heat input, and repeatable technique. TIG Welding Secrets distills years on the bench into step-by-step sequences you can execute: joint prep, tungsten and cup selection, purge and trailing shield setup, torch angle, filler timing, and travel speed calibrated to thickness.

Developed with veteran instructors and code-qualified fabricators, this guide provides parameter windows for 304/316 from 0.8–6 mm, color-control standards, and troubleshooting trees for sugaring, distortion, porosity, and arc wander. Learn pulse settings that lock in penetration without overheating, fixture strategies to keep parts straight, and finishing methods that preserve corrosion resistance. Practical, tested, and immediately usable inside TIG Welding Secrets.

• Setup matrices: gas lens/cup, tungsten grind, and purge flow by joint and thickness.
• Heat control: amperage, pulse frequency, and travel speed to prevent warp and sugar.
• Fit-up and finish: gap targets, backing solutions, pass sequencing, and color checks.
