The Welding Coupons 1/8 inch practice kit contains seven laser-cut pieces of steel listed as 11 gauge, designed for beginners who want to practice welds and assemble a six-sided dice project. It is a sensible, low-cost way to get seat time on 1/8 inch material, and a poor buy if you need variable thicknesses or large pieces for coupon testing. Check the listing for the exact piece size, since this review relies on seller descriptions.

What the Kit Is and Who It Suits
Practice coupons are small, flat steel pieces that you weld together to practice your technique. Laser cutting gives clean, square edges, so fit-up is more consistent than hand-cut scrap.
This kit targets beginners who want to practice the joints that matter most: butt joints, fillets and lap joints on a thickness of 1/8 inch. The seller also suggests a dice project, which gives a goal instead of random practice.
It suits new welders learning MIG, stick or TIG on mild steel. It is less useful for advanced welders who need coupons of different thickness or for those who test qualification welds, which require specific coupon sizes.
How to Check the Kit Fits Your Setup
- Verify the thickness. Standard 11 gauge steel is about 0.12 in, which the seller rounds to 1/8 inch. Make sure your welder can weld this thickness cleanly.
- Check the piece sizes. The listing should list length and width. Sizes affect how many practice beads you can lay down.
- Check the material. Mild steel is easy for beginners. If the listing is unclear, ask the seller or check recent buyer comments.
- Plan your process. MIG with 0.030 or 0.035 inch wire, stick with common rods and TIG with filler can all work. Pick the settings on your machine’s chart.
- Prepare the metal. Laser-cut edges may have oxide. Clean to bright metal before you weld.
Pros and Limitations
Pros
- Clean laser-cut edges for repeatable fit-up
- 1/8 inch is a useful teaching thickness
- Dice project gives a goal
- Low-cost way to practice with real material
Limitations
- Only seven pieces, so you will run out of material quickly
- Single thickness only
- Listing describes the material inconsistently
- Laser-cut edges need cleaning
Practice Tips and Safety
- Clamp or tack the coupons so they do not shift. Use magnets or small clamps to keep corners square.
- Practice one skill at a time: first stringer beads, then butt joints, then fillets.
- Look at the bead after each pass: consistent width, no undercut, no cold lap.
- Let coupons cool in air. Do not quench steel you want to test for bend behavior.
- Wear a helmet with correct shade, gloves, long sleeves and eye protection when grinding.
- Weld in a ventilated area. Remove oil and coatings first, and avoid welding coated or galvanized metal.

Frequently Asked Questions
What thickness are the coupons in this practice kit?
The listing describes 1/8 inch, 11 gauge steel. Standard 11 gauge steel sheet is about 0.12 inch, close to 1/8 inch, so the figures are consistent in practice. Confirm the exact thickness and piece sizes on the listing before buying.
Are these coupons mild steel or medium carbon steel?
The listing text uses both terms, so confirm the material in the product details. Mild steel is the usual coupon material and welds easily with MIG, stick and TIG. If you plan to weld a carbon-heavy steel, follow the correct process.
What welding machine do I need for 1/8 inch steel?
A machine rated for 1/8 inch steel at your input voltage. Many 120 V MIG units can weld this thickness in light duty, but multi-pass welds and fillets are easier on a 240 V welder. Check your machine’s thickness chart and duty cycle.
Can I reuse practice coupons?
Yes. Grind or cut off old welds, clean the surface and weld again. Each time you remove metal, the coupon gets thinner or smaller, so keep an eye on fit-up and burn-through risk. Always wear PPE when grinding.
Final Thoughts
This seven-piece kit is a useful beginner practice set for 1/8 inch steel, especially if you want a simple dice project. Verify the piece sizes and material before buying.
