Welding Stainless Mug: Master Thin‑Wall TIG Without Warp or Sugar

If welding a stainless mug has ever left you with blue heat tint, pinholes, or a warped rim, you’re fighting the classic thin‑wall TIG problem: too much heat, not enough control. TIG Welding Secrets distills proven shop methods for 304/316 mugs and tumblers into clear, repeatable steps—so your seams are sanitary, straight, and tight on the first pass.

Inside, you’ll get practical setups that work: precise torch angles, arc length discipline, and pulse baselines for 0.5–1.0 mm walls; tungsten, cup, and gas lens choices that stabilize the puddle; filler selection that wets without piling; and back‑purge tactics that stop oxidation without wasting argon. You’ll learn tack sequencing to lock roundness, copper mandrel and chill strategies for heat control, and an interpass routine that prevents distortion. Finishing protocols cover oxide removal and passivation for food‑safe, neutral‑taste results.

Built from real shop procedures, TIG Welding Secrets removes guesswork with parameter ranges, fixture sketches, purge setups, and a pre‑weld checklist that catches fit‑up, gap, and cleanliness issues before they become defects. Whether you’re fabricating boutique drinkware or dialing in stainless practice coupons, you’ll have a reliable path to clean, repeatable stainless mug welds that hold pressure, polish evenly, and look professional under any light.

• Dialed‑in parameters for 304/316 thin‑wall: tungsten size, cup/gas lens, cfh, and pulse ratios.
• Cost‑smart back‑purge methods that eliminate sugar and heat tint at the root.
• Distortion control, finish, and passivation workflow for food‑grade results every time.
