Stainless Steel TIG Welding Guide for Predictable, Clean Results

Real-world stainless work demands tight heat control, clean roots, and consistent color. This stainless steel TIG welding guide distills proven procedures—prep, parameters, purge, and post-clean—into repeatable steps you can trust in the booth or the field. Built from shop-tested methods and QA-backed standards, it eliminates guesswork and helps hold spec on 304/316, from thin sheet to sanitary tube.

Inside Everything You NEED to Know About TIG Welding, the stainless section delivers WPS-style settings by thickness, with tungsten size and grind, gas lens and cup selection, argon flow windows, and filler choices like ER308L and ER316L. Learn fixture strategies to limit distortion, interpass temperature control, pulse presets for heat input management, back-purge setups with oxygen targets, and color control from straw to chrome. Troubleshooting maps address sugaring, pinholes, undercut, and crater cracks, with practical fixes and inspection criteria, plus guidance on post-weld cleaning and passivation for durable corrosion resistance.

• Quick-start charts for 0.5–6 mm sheet and tube: amperage, pulse (PPS/duty/background), travel speed, and torch angle.
• Gas and hardware clarity: 2% lanthanated tungsten, gas lens use, #12–#15 cups, 12–25 CFH argon, trailing shields, and purge flow/venting best practices with sub-50 ppm targets.
• Repeatable quality: setup checklists, color acceptance visuals, and step-by-step remedies for warping, contamination, and lack of fusion.
