Stainless Steel Welding Practice Kit —
201 SS Coupons for MIG, TIG & Stick
Improving your welding takes repetition on real metal — not cardboard cutouts or simulated surfaces. This stainless steel welding practice kit gives you precision-cut 201 stainless steel coupons to burn through, so you can focus on bead consistency, travel speed, and fusion quality without worrying about the quality of your practice material.
Available in two kit formats — the Perris Welding Practice Kit with square and Perris-shaped coupons for joint practice, and the Poker Welding Practice Kit with a multi-piece set for building dimensional projects. Both are cut from corrosion-resistant 201 stainless steel with smooth, uniform edges that make positioning, clamping, and restarting easy. Compatible with MIG, TIG, and Stick processes.
Two Kit Options
Perris Practice Kit vs Poker Practice Kit
Choose the kit that matches how you practice. The Perris kit is optimized for flat and joint weld practice with uniform coupon pairs. The Poker kit is a multi-piece set that assembles into a dimensional project — giving you straight seams, inside corners, and butt joints all in one build.
Practice Kit
Twelve coupons in two shapes — six square plates and six Perris-shaped plates. Uniform dimensions make it easy to set up repeatable joint configurations for flat, butt, T-joint, and lap joint practice. Consistent sizing means you can run the same setup multiple times to track your improvement.
Practice Kit
Seven pieces in varied dimensions that assemble into a finished three-dimensional project. Each piece presents a different joint geometry — you get practice on multiple weld types in a single build, and end up with a completed metal object you can keep or use as a skill benchmark.
Why 201 Stainless Steel
Practice Material That Doesn't Fight You
The quality of your practice coupons directly affects the quality of your practice. Rusted, warped, or poorly cut steel introduces variables that have nothing to do with your technique — making it harder to isolate what you're actually working on. 201 stainless steel eliminates those variables.
Ready to Weld Without Prep
201 stainless steel resists rust and surface oxidation, so coupons stay clean and ready to use straight out of the box — no grinding, no wire brushing, no prep work before you can put a bead down. The material maintains its shape and flatness without warping in storage or under shop conditions, so every coupon you pull from the kit is as usable as the first one.
Feature Breakdown
What Makes These Coupons Work
Every coupon is cut to the same dimensions within the kit, so you can set up the same joint configuration repeatedly and compare beads side by side. Inconsistent coupon dimensions make it impossible to isolate technique variables — these are cut to be consistent so your results reflect your skill, not your material.
Sharp, ragged edges on practice coupons create fit-up problems and are a hand hazard. These coupons are finished with smooth edges out of the box. Position them against each other or against a fixture and they sit flat without gaps caused by edge burrs — which is exactly what you want when you're practicing root pass control and joint fit-up.
201 stainless steel at 0.056–0.06 inch thickness works across all three common welding processes. MIG with stainless wire or tri-mix shielding gas, TIG with ER308L filler, or Stick with stainless electrodes — the material responds appropriately to each process and provides realistic feedback on heat input, travel speed, and penetration.
At 0.056–0.06 inches, the thickness is thin enough to be forgiving on heat input errors — you can see immediately when you've got the heat too high or too low — but substantial enough to practice realistic weld profiles. It's the sweet spot for beginners learning settings and intermediates dialing in consistency.
Square and Perris shapes in the first kit give you both matching-size pairs for butt joints and differently-shaped pairs for T-joints and lap joints. The Poker kit's dimensional pieces present inside corners, outside corners, and straight seams in a single build. More joint variety per kit means more types of practice before you run out of material.
