How to TIG Weld Stainless Steel with Consistent, Code‑Ready Results

If you’re searching how to TIG weld stainless steel, you know stainless punishes guesswork—small slips in heat, cleanliness, or gas coverage show up as sugaring, heat tint, and distortion. TIG Welding Secrets distills the exact procedures pros use to deliver clean roots and mirror caps on 304/316, first time.

Built from years on the bench and instructor-grade checklists, this guide turns stainless into repeatable steps: joint prep and fit-up, DCEN fundamentals, torch angle discipline, pulse tuning, and amperage charts by thickness. Get filler selection shortcuts (ER308L/ER316L), cup sizes and flow rates that truly shield, proven back-purge setups for tube and sanitary work, and heat-control tactics that cut rework. Designed for fabricators, makers, and maintenance teams who need predictable, inspection-ready welds without trial and error.

• Dial-in settings by alloy/thickness: amps, pulse, cup size, and gas flow.
• Backside protection made simple: purge tooling, dams, and paste.
• Fast fixes for real defects: crater cracks, sugaring, porosity, warp.
