Welding Stainless Mug with TIG: precise heat control, food‑safe results

Thin stainless demands discipline. If you’re tackling a welding stainless mug project, the difference between a sanitary, warp‑free seam and a burnt, sugared mess comes down to torch control, gas coverage, and metallurgy. “Everything You NEED to Know About TIG Welding” distills proven shop procedures for 304/316 into clear, repeatable steps—so your welds stay tight, bright, and inside‑clean.

Built from real fabrication workflows used on food‑grade stainless, this guide gives you exact starting parameters, fixture and purge strategies, filler selection, and post‑weld finishing that preserves corrosion resistance. You’ll learn how to manage heat input on thin wall, keep the interior sugar‑free with stable backpurge, read color as a quality signal, and blend seams without over‑polishing. Expect practical charts, WPS‑style recipes, troubleshooting flowcharts, and photo walk‑throughs that turn theory into consistent results—on mugs, tumblers, and any thin‑gauge stainless assembly.

• Dial in amperage, pulse, cup size, and gas lens setup for 0.8–1.5 mm stainless—clean beads with minimal distortion.
• Backpurge and fixturing methods that prevent pinholes and interior oxidation while holding parts true.
• Filler metal selection (308L/316L), joint prep, color control, and passivation for durable, food‑safe finishes.
