Practicing welds is easier when you have clean, consistent metal pieces instead of random scrap with unknown thickness, coatings, or rough edges. Glarks Welding Coupons are small carbon steel practice plates made for MIG, TIG, and arc welding exercises. This review helps you decide if the 150mm x 50mm x 1/8 inch size, five-piece count, and carbon steel build make sense for your training setup. They are a practical choice for learning bead control and joint practice, but they are not a replacement for project-ready structural steel.
Quick Verdict
Rating: 8/10
Best For: Beginners, welding students, and hobby welders who want consistent carbon steel coupons for repeat practice.
Bottom Line: Glarks Welding Coupons are worth considering if you want ready-to-use steel practice pieces with a manageable 1/8 inch thickness. The main tradeoff is that the five-piece pack can run out quickly if you are doing repeated bead, tack, and joint practice.

What Are the Glarks Welding Coupons?
Glarks Welding Coupons are small carbon steel plates made for welding practice. Each coupon measures 150mm long by 50mm wide with a 1/8 inch thickness, which gives you enough surface area to practice bead placement without handling large sheet stock.
The five-piece set is useful if you want repeatable practice material for MIG, TIG, or arc welding. Instead of cutting down random scrap, you can start with matching pieces that make it easier to compare your welds from one practice session to the next.
The product description highlights smooth surfaces, smooth edges, and anti-oxidation properties. Those details matter because rough or dirty metal can make early welding practice more frustrating, especially when you are still learning heat control, travel speed, and bead consistency.
Before You Buy: These are practice coupons, not finished project parts. Check the size, thickness, and material against your welding machine settings, class requirements, or project plan before ordering.
Who Should Buy It?
Best For
- Beginners who want a simple carbon steel coupon for welding practice.
- Students practicing MIG, TIG, or arc welding techniques on matching pieces.
- Hobby welders who need small coupons for bead control, tack welds, and test passes.
Skip If
- You need a larger quantity for a long class, repeated certification prep, or group training.
- You need stainless steel, aluminum, thicker plate, or a specific alloy for your welding process.
- You need structural material for a load-bearing project instead of practice pieces.
Material Quality and Durability
The main strength of these Glarks coupons is the carbon steel construction. Carbon steel is a common practice material because it is widely used, familiar to many welding students, and suitable for learning how heat, filler, and travel speed affect the finished bead.
The 1/8 inch thickness gives the coupons more substance than very thin sheet metal. That helps if you are practicing short beads, tacks, fillets, and heat control. It can also be more forgiving than thin sheet when you are learning to avoid burn-through.
The product description says the coupons have smooth surfaces and edges that are free from burrs. That can reduce prep time, although you should still inspect each piece before welding. Wipe away oil, dust, or residue, and follow the setup steps recommended for your specific welding process.
Ease of Use for Beginners
For a beginner, the biggest benefit is consistency. When each coupon has the same size and thickness, you can focus on your weld settings, angle, travel speed, and puddle control instead of guessing how one piece of scrap differs from another.
The 150mm x 50mm size is compact enough for a small workbench, welding cart, or school practice station. It also gives you room for several short practice beads on one face before you flip the piece or move to the next coupon.
Because the pack includes five coupons, you can use one for setup, one for bead practice, and others for different welding methods. That said, five pieces may feel limited if you plan to practice for several sessions.
Pro Tip: Mark each coupon with your welding process, amperage or voltage setting, and wire or filler size before practice. This makes it easier to compare results and repeat the setup that worked best.
Versatile Applications in Welding
These coupons can support several types of practice, including MIG, TIG, and arc welding. That makes them useful if you are still deciding which process you want to improve or if your class covers more than one method.
For MIG practice, the flat coupon size works well for learning bead spacing, gun angle, and travel speed. For TIG practice, the carbon steel surface lets you work on puddle control and filler timing. For arc welding, the 1/8 inch thickness gives you a practical surface for strike starts, short beads, and basic technique drills.
The coupons also work as small test pieces before you move to a larger project. You can check machine settings, practice a joint layout, or test your hand position before using your final material.
How It Performs in Real Use
For Daily Practice
For daily welding practice, these coupons are simple and predictable. You can set them on a bench, clamp them in place, and run repeated beads without needing to cut material first. The small size also makes cleanup and storage easier after a short session.
For Welding Classes
In a class setting, the five-piece count can help you complete basic drills, but it may not be enough for a full course. If your instructor requires a certain number of coupons, a certain joint type, or a different alloy, check those requirements before you buy.
For Machine Setup
These coupons are useful when you want to test settings before working on a real project. You can adjust heat, speed, wire feed, filler control, or rod angle on a coupon first, then compare the bead shape and penetration before moving forward.
For Small Project Planning
The coupons can help you test a welding approach before using larger carbon steel pieces. They are not large enough for every project layout, but they can give you a quick read on technique, fit-up, and surface prep.
How to Use These Coupons Correctly
Start by checking each coupon for dirt, oil, moisture, or surface residue. Even when a practice coupon looks smooth, a quick wipe and proper prep can help your weld behave more predictably.
Clamp the coupon securely before welding. A loose coupon can shift while you work, which affects bead placement and can create a safety risk. Use a stable welding table or approved work surface, and keep flammable materials away from the work area.
Use the coupon size and thickness when choosing your settings. A 1/8 inch carbon steel piece will not behave the same as very thin sheet, thick plate, stainless steel, or aluminum. Follow your welder manual, filler material guidance, and class instructions when setting amperage, voltage, wire feed, or rod choice.
Safety and Material Notes
These coupons are made for welding practice, so proper safety gear is required. At minimum, use a welding helmet with the correct shade, welding gloves, protective clothing, closed-toe footwear, and eye protection. You should also work in a ventilated area that is suitable for welding.
Carbon steel can rust if it is left wet or stored in a damp area. The product description mentions anti-oxidation properties, but you should still keep the coupons dry and store unused pieces indoors. After practice, allow hot metal to cool fully before handling or storing it.
Do not use practice coupons as structural parts unless you know the material requirements, welding procedure, and load demands for the job. For anything safety-critical, follow professional guidance and applicable welding standards.
Pros and Cons
Pros
- Carbon steel construction suits common MIG, TIG, and arc welding practice.
- 150mm x 50mm size gives you a manageable surface for short beads and drills.
- 1/8 inch thickness is practical for beginner heat-control practice.
- Five matching coupons make it easier to compare results across practice sessions.
- Smooth surfaces and edges can reduce prep frustration for new welders.
Cons
- Five pieces may not be enough for long-term practice or group use.
- Not suitable if you need stainless steel, aluminum, or thicker plate practice.

Is It Worth the Price?
Glarks Welding Coupons offer strong value for the price if you want ready-sized carbon steel practice pieces without cutting your own material. The value is strongest for beginners, hobby welders, and students who need small, consistent coupons for repeat drills.
They are not the best fit if you need a large training batch, specialty metal, or project-sized stock. For simple practice on carbon steel, the combination of five pieces, 1/8 inch thickness, and compact 2 inch x 6 inch format makes them a smart buy for everyday welding practice.
How It Compares to Alternatives
Compared with random scrap metal, these Glarks coupons give you more consistency in size and thickness. Scrap may be cheaper, but it can come with coatings, rust, uneven thickness, or unknown material that makes beginner practice harder to judge.
Compared with stainless steel or aluminum coupons, these carbon steel pieces are better for welders focused on common mild steel practice. If your class or project requires another alloy, choose coupons that match that exact material instead.
