🔥 WELDING DEFECTS EXPLAINED – MASTER YOUR BEAD LIKE A PRO 🔥
If you’ve ever struggled to get that perfect weld bead, this visual breakdown is exactly what you need. Welding isn’t just about melting metal—it’s about control, precision, and understanding how travel speed and current affect your final result. Whether you're into MIG welding, TIG welding, stick welding, or flux-core welding, these common welding defects can make or break your project.
Let’s break it down 👇
Normal Welding (Perfect Bead)
This is what you’re aiming for: a smooth, even weld bead with consistent ripple pattern, proper pe*******on, and clean edges. It shows balanced amperage, voltage, and travel speed—the key to strong, durable welds.
Speed Too Slow
Moving too slowly causes excessive heat buildup. The weld becomes wide, overly convex, and can lead to burn-through or distortion. This is a common mistake in beginner welding—slow down your heat, not just your hand.
Speed Too Fast
Too fast means poor fusion. You’ll notice a narrow, uneven bead with weak pe*******on. This type of weld may look okay at first glance but can fail under stress. Always maintain a steady hand and consistent pace.
Welding Current Too High
Excessive current leads to spatter, undercut, and a rough, messy weld pool. It can weaken the structure and ruin the appearance. Control your amps and voltage settings to avoid overheating the base metal.
Welding Current Too Low
Low current results in poor pe*******on and a weak bond. The bead may look thin, inconsistent, and sit on top of the metal instead of fusing into it. This is a critical issue in structural welding.
Pro Welding Tips for Better Results
* Keep a consistent arc length
* Match your amperage to material thickness
* Maintain steady travel speed
* Use the correct electrode or filler material
* Clean your base metal before welding
* Practice bead control on scrap before real projects
Whether you're working on DIY metal projects, automotive welding, pipeline welding, fabrication, or repair work, understanding these welding defects will dramatically improve your skills and results.
