Welds That Work: How to Tell Good Welding from Bad (and Why It Matters)

Not all welds are created equal. In fact, a weld might look smooth from the outside but fail under pressure if it wasn't done right. At JAMM Fabrication, we take weld quality seriously because we know our work goes into homes, businesses, and builds where strength, safety, and precision matter.

If you're a contractor, builder, or even a homeowner curious about how your project is holding together, here are the telltale signs of a quality weld and why it makes all the difference.

1. The Weld Looks Clean and Consistent

Good welds should look like a steady, even stack of dimes. They’ll be uniform in width, not overly wide or messy, and won’t have pits, holes, or jagged edges. Consistency shows that the welder had the right speed, angle, and settings, which means the weld is likely to hold up well.

Pro tip: Surface appearance isn’t everything, but it’s a strong clue.

2. There Are No Cracks or Porosity

Cracks are a red flag, period. Porosity - tiny holes or bubbles - can weaken a weld and make it prone to failure. These flaws can result from poor technique, dirty metal, or the wrong shielding gas. We inspect every weld to make sure nothing sneaky gets through.

3. The Weld Penetrates Properly

This is the part you can’t always see, but it’s critical. Proper penetration means the weld fused deeply into the base metal. Without it, the weld might snap under stress. At JAMM, we test our setups to make sure our welds don’t just sit on the surface - they become part of the structure.

4. It Passes the Test (Literally)

Weld inspections are real. For structural projects, welds often need to meet specific codes and certifications. Whether it's a bend test or visual inspection, quality welding passes the test. Our team includes certified welders who know exactly what those standards are and how to meet them.

Why It All Matters

Welding isn’t just melting metal together. It’s a craft that holds buildings, staircases, supports, railings, and equipment together. A weak weld can compromise safety, delay your build, or cost you money in the long run. A strong one? It becomes part of the backbone of your project.
