How to TIG Stainless Steel: clean color, tight control, repeatable results

Searching how to TIG stainless steel? The difference between rainbow haze and food‑grade silver comes down to disciplined setup and heat control. Everything You NEED to Know About TIG Welding distills the exact process: DCEN, properly prepped joints, dedicated stainless brushes, sharpened 2% lanthanated tungsten, gas lens with the right cup, argon at 15–25 CFH (cup‑dependent), tight arc length, correct 308L/316L filler, and verified back‑purge to stop sugaring. It’s a practical, step‑by‑step system built for consistent color and distortion control.

Developed from thousands of production joints, this guide gives you parameter ranges by thickness, pulse strategies for thin stock, purge setups that protect the root, and fixture tactics that keep parts straight. Expect shop‑proven checklists, quick diagnostics, and clear visuals—so you can move from guesswork to repeatable, inspection‑ready welds.

• Thickness‑specific amps, travel speed targets, torch angles, and filler selection.
• Purge flow charts, dams, and trailing techniques for sugar‑free roots and even heat tint.
• Fast fixes for porosity, blow‑through, undercut, and color banding—plus prevention steps.
