Comprehensive FAQ on Best Welding Practices In Fabrications

What is the standard thickness for general welding practice coupons?

While thicknesses vary widely based on the intended application, a great starting point for beginners is 1/8 inch (11 gauge, like the Hilitchi kit) or 14 gauge (WelderElite kit). These gauges are thin enough to teach heat control (preventing burn-through) but thick enough to run a solid bead. Industrial fabrication often demands practice on 1/4 inch or thicker plate to master multi-pass techniques.

Do I need different practice kits for TIG versus MIG welding?

You don’t necessarily need different kits, but you should choose the thickness based on the process. MIG welding (especially spray transfer) typically works better on thicker material (1/8″ or 1/4″) because it requires higher heat input. TIG welding requires finer control and is often used on thinner sheet metal fabrication, making 16 gauge or 14 gauge coupons more useful for that practice.

Why is fit-up so important in fabrication practice?

Fit-up refers to how perfectly the edges of the pieces match before welding. In professional fabrication, poor fit-up wastes time and money because you have to use excessive filler material or grind heavily. Kits like the WelderElite, with their precision laser-cut edges, are fantastic for training your eye to spot and correct poor joint alignment, which is critical for strong welds.

Should I prep my practice coupons before welding?

Absolutely. Proper coupon preparation is one of the most important steps in quality welding. You should remove mill scale, rust, or oil using a grinder or wire brush, especially along the joint edges. For stainless steel, as found in the Leinuosen kit, preparation must be meticulous, using dedicated stainless steel brushes to prevent carbon contamination.

How do I prevent metal distortion when practicing thin metal fabrication?

Distortion happens when intense, localized heat causes the metal to expand and contract unevenly. When using thin materials (16 gauge), you can prevent distortion by using tack welds strategically to hold the assembly in place, using lower amperage, and employing skip welding or intermittent welding techniques to allow the previous section to cool slightly before adding more heat.

What’s the main advantage of using mild steel for practice over other alloys?

Mild steel (low carbon steel) is the most forgiving and cost-effective material. It’s the easiest metal to practice all the fundamental welding practices on—including bead formation, travel speed, and penetration—before moving onto more challenging or expensive alloys like stainless steel or aluminum.
