Learning to weld is easier when you have clean, consistent metal pieces instead of random scrap with unknown thickness. The Therwen 5 Pieces Welding Practice Kit gives you five 16-gauge mild steel coupons in different shapes, so you can work on control, bead placement, fit-up, and basic joining practice. It is best for beginners who want simple practice pieces before moving to real repairs or fabrication. The main limitation is clear: this kit gives you practice material, but it does not replace proper welding instruction, safety gear, or a larger supply of steel for repeated training.

What Is the Therwen 5 Pieces Welding Practice Kit?
The Therwen 5 Pieces Welding Practice Kit is a small set of mild steel welding coupons made for hands-on practice. The article-supported details show five 16-gauge pieces, including square and triangular shapes. That mix gives you more practice variety than a single flat strip.
This kit makes sense when you want a simple, ready-to-use practice set for learning bead placement, heat control, tack welds, and basic joining. You can use it before trying a visible repair or a more expensive project. It also suits creative practice because the pieces can become small decorative items after welding.
Before You Buy: This is a small 5-piece practice kit, not a large coupon pack. If you plan to run many test beads every day, you may need extra practice steel.
Who Should Buy It?
Best For
- Beginners who want consistent 16-gauge mild steel practice pieces.
- Hobby welders who want to test bead control before starting a small project.
- Students or DIY users who want simple coupons for tacking, positioning, and layout practice.
Skip If
- You need a bulk pack for repeated daily welding drills.
- You need verified dimensions, a specific joint design, or a certified training coupon set.
- You want a complete welding course with instructions, filler metal, clamps, or PPE included.
Benefits for Beginners
The biggest benefit is consistency. Random scrap metal can vary in thickness, coating, rust, and shape, which makes it harder to judge your progress. With this kit, you start with article-supported 16-gauge mild steel pieces and a small set of repeatable practice coupons.
The five-piece count also gives you room to practice more than one skill. You can dedicate one coupon to straight beads, another to tacks, and another to fit-up or decorative layout. That approach helps you see what changed between attempts instead of guessing.
| Feature | Why It Helps |
|---|---|
| Five practice pieces | Lets you separate different practice drills instead of crowding every weld onto one coupon. |
| 16-gauge mild steel | Gives beginners a common steel type and thickness for basic welding practice. |
| Square and triangular shapes | Supports simple layout practice, tacking, positioning, and creative arrangements. |
| Reusable for projects after practice | Lets you turn practice pieces into small decorative items when the welds are clean enough. |
Materials and Build Quality
The kit uses 16-gauge mild steel, which is a practical material for beginner welding practice. Mild steel is common in small fabrication and repair work, so practicing on it can help you build useful basic habits.
The 16-gauge thickness gives you enough material to practice control, but you still need to watch heat input. Beginners can burn through thinner steel when they move too slowly or run settings too hot. That makes these coupons useful for learning travel speed, tack spacing, and heat control.
Shape Variety and Practice Value
The square and triangular coupon shapes give you more layout choices than plain rectangular strips. You can practice straight beads on flat areas, then move to corners, edges, and small tack points. That variety helps you train your hand position instead of repeating the same motion on every piece.
The different shapes also support basic project planning. You can arrange the coupons before welding, check how the edges meet, and decide where tack welds should go. That step matters because many beginner mistakes happen before the arc starts.
Ease of Use
The Therwen kit is simple because it does not require assembly before practice. You can place the coupons on a welding table, secure them with clamps or magnets, clean the weld area, and start with basic bead or tack practice.
You should still prep the surface before welding. A wire brush, flap disc, or grinder can help remove surface debris from the area you plan to weld. Clean metal helps you get a steadier arc and makes your practice results easier to judge.
Pro Tip: Number each coupon with a marker before you begin. Use one for straight beads, one for tacks, one for corner practice, and one for a small creative project so you can track progress.
Versatile Uses Beyond Practice
Although the kit is made for practice, the coupons can also support small decorative projects. The article notes possible uses such as table centerpieces and window adornments. That makes the kit more engaging than scrap pieces you throw away after testing.
You can also use the pieces to practice layout and customization. For example, you can arrange the shapes, tack them together, check alignment, then finish the welds after you like the design. This gives you a low-pressure way to build both welding control and creative confidence.
How It Performs in Real Use
For First Welding Practice
For a new welder, the kit gives you defined pieces that are easier to manage than random scrap. You can focus on bead consistency, starts, stops, and heat control without sorting through metal of unknown thickness.
For Tack Weld Practice
The varied shapes are useful for tacking because you can line up edges and corners before committing to a full weld. This helps you practice holding pieces in position, checking fit, and avoiding movement during the weld.
For Small Decorative Projects
The square and triangular pieces can become simple art or display items once you are comfortable with the welds. This gives beginners a practical reason to improve appearance, grinding, and finishing.
For Long-Term Skill Building
The kit can start your practice routine, but five coupons will not last forever. Once you fill the surfaces with beads or cut the pieces into smaller sections, you will need more steel for continued daily practice.
Setup Tips Before First Use
- Clean the weld area first: Use a wire brush or grinder to remove debris from the area you plan to weld.
- Clamp the coupons securely: Do not rely on hand pressure while welding. Secure the pieces on a safe welding surface.
- Start with short beads: Short welds help you control heat and compare your starts and stops.
- Practice one skill at a time: Separate beads, tacks, corners, and decorative layouts so you can see clear progress.
- Let the steel cool: Small coupons can heat quickly. Give them time to cool before handling or repositioning.
Safety and Material Notes
This kit is practice metal, but welding still carries real safety risks. Use a proper welding helmet, gloves, flame-resistant clothing, eye protection, and safe footwear. Work in a suitable area with ventilation and keep flammable materials away from sparks.
Because the coupons are 16-gauge mild steel, heat control matters. Follow your welder settings guide, use the right process for your machine, and avoid touching the coupons until they cool. If you are learning in a class, follow your instructor’s safety rules first.

Is It Worth the Price?
The Therwen 5 Pieces Welding Practice Kit is worth considering if you want a small, ready-to-use set of mild steel coupons for beginner drills. Its value comes from convenience, shape variety, and the ability to practice on consistent material instead of searching for scrap.
It is a smart buy for occasional practice, class prep, hobby work, or creative welding exercises. It is not the best fit if you need a large quantity of coupons, verified dimensions for a formal test, or a complete training bundle with accessories.
How It Compares to Alternatives
Compared with loose scrap metal, this kit gives you a more predictable starting point because the article identifies the material as 16-gauge mild steel. Scrap can still be cheaper, but it may be dirty, coated, warped, or inconsistent.
Compared with larger coupon packs or formal training sets, the Therwen kit is simpler and smaller. Choose it for casual practice and creative layouts. Consider a larger pack if you need many repeated welds or structured certification-style practice.
