These 17 gauge welding practice coupons come as a 24-piece set of pre-cut, 17-gauge cold-rolled low-carbon steel pieces for learning tacks, beads and simple joints. They suit beginners who want consistent material without cutting scrap. The main limit is thickness: 17 gauge is thin, so it teaches heat control but cannot stand in for thicker plate.
This guide covers what the listing says is in the set, who it suits, how to practice with it and where it falls short. The 17-gauge steel in this set is thinner than the 11-gauge kit in our WelderElite practice coupons kit review.

Who the coupons suit
They suit beginners and hobby welders who want clean, repeatable practice pieces. Laser-cut edges mean the pieces fit together square, so you can focus on tack placement, heat control and bead consistency instead of preparing metal.
They are less useful if you need thick plate for fillet or groove practice, stainless or aluminum coupons, or a large quantity for daily practice. Twenty-four small pieces go quickly.
How to practice with them
- Clean each piece of oil and mill scale where you will weld.
- Start with straight beads on a flat piece to find a travel speed that does not burn through.
- Move to tack welds on an edge joint or corner, placing tacks at even spacing.
- Build a small frame, bracket or cube to practice fit-up and controlling distortion.
- Change one setting at a time and write the settings on the piece with a paint marker.
Wear a welding helmet, gloves and flame-resistant clothing, and ventilate the work area. Remove flammables from the bench before you strike an arc.
Pros and limitations
Pros
- Pre-cut, consistent pieces save prep time
- Laser-cut edges give squarer fit-up
- Thin steel makes heat-control mistakes obvious
- Small enough for a home bench
Limitations
- 17 gauge is thin and burns through easily at high heat
- Only 24 pieces, so heavy practice uses them fast
- Mild steel only, with no stainless or aluminum
- Piece shapes and sizes should be confirmed on the listing

Frequently Asked Questions
What are the 24-piece steel welding practice coupons made of?
The listing describes 17-gauge cold-rolled low-carbon steel with laser-cut edges. Check the current listing for the exact piece shapes and sizes.
How thick is 17-gauge steel?
On the standard sheet-steel gauge chart, 17 gauge is roughly 0.054 in (about 1.4 mm). Thin steel like this teaches heat control, but it burns through easily if the settings are too hot.
Which welding processes can I practice with them?
Mild steel this thin suits MIG and TIG best. Stick welding is possible but harder on thin material. Use the settings recommended for your welder and wire or rod.
How do I prepare the coupons before welding?
Wipe off any oil, then wire-brush or sand the weld area until it is bright metal. Clean steel gives a more consistent arc and a better bead.
How should I store them?
Keep them dry, because bare low-carbon steel rusts. A closed container in a dry shop works, and a light oil film helps if you store them a long time.
Verdict
A tidy beginner set for MIG and TIG practice on thin mild steel. Buy it for fit-up and heat-control drills, and choose thicker coupons if you want plate-style practice.
