How to TIG Weld Stainless without warping, sugar, or wasted time

If you’re searching for how to TIG weld stainless, you’re likely chasing color control, distortion, and root integrity. Everything You NEED to Know About TIG Welding condenses shop-proven procedures for 304/316 sheet and tube—covering DCEN polarity, gas lens setups, 100% argon flow, cup selection, pulse windows, travel speed, and disciplined back purging. It details parameter ranges by thickness, tungsten type and grind, filler selection (308L, 316L), and fit-up techniques that prevent oxidation—so welds stay straw-to-silver with sound roots and minimal cleanup.

Built by working procedure writers and trainers, and validated on food-grade, aerospace prototype, and architectural stainless. Expect WPS-style checklists, step-by-step joints, and troubleshooting flows with real settings for popular inverters—no fluff, just the variables that move results from “acceptable” to repeatable.

• Purge control recipes: dams, venting, 15–25 CFH, oxygen targets under 50 ppm.
• Distortion management: tack sequence, chill bars, pulse ratios, interpass timing.
• Repeatable starts/stops: arc length, wire angle, crater fill, post‑flow timing.
