Do you ever lie awake at night worrying about the integrity of your welds? You’re not alone. Welding defects can be a hidden menace, lurking beneath the surface and waiting to cause problems down the road. But fear not! In this post, Quality Welding and Inspections will shed light on 5 common welding defects, and more importantly, how our expert inspections can ensure your welds are strong, safe, and built to last.
1. Lack of Fusion: Imagine a weld that looks good on the outside, but the two pieces of metal are never truly joined. That’s lack of fusion. This defect can be caused by improper heat input, poor joint fit-up, or contamination. The result? A weak weld prone to cracking and failure.
How Quality Welding and Inspections Prevents It: Our inspectors have a keen eye for proper joint preparation and ensure the welder uses the correct technique and heat settings. We also use non-destructive testing (NDT) methods to verify complete fusion throughout the weld.
2. Porosity: Tiny gas bubbles trapped inside the weld? That’s porosity. It can happen when contaminants like moisture, rust, or oil are present on the welding surface. Porosity weakens the weld and can even create leaks.
How Quality Welding and Inspections Prevents It: We emphasize meticulous cleaning procedures before welding. Our inspectors ensure proper shielding gas coverage (if applicable) to prevent air from contaminating the weld pool.
3. Cracks: Cracks are a serious defect that can significantly compromise the strength of a weld. They can be caused by cooling stresses, improper welding technique, or the use of the wrong filler metal.
How Quality Welding and Inspections Prevents It: Our inspectors verify the suitability of the base metal and filler metal for the project. We also ensure the welder uses proper travel speeds and heat input to minimize shrinkage stresses that can lead to cracking.
4. Undercut: This defect looks like a groove melted into the base metal next to the weld. It happens when the welding arc digs too deeply. Undercut weakens the joint and can create stress concentration points.
How Quality Welding and Inspections Prevents It: We ensure the welder uses the right angle and travel technique to prevent excessive penetration. Our inspectors meticulously examine the weld for undercut during inspections.
5. Spatter: While not a structural defect, excessive spatter makes the weld look messy and unprofessional. It’s caused by molten metal droplets expelled from the arc.
How Quality Welding and Inspections Prevents It: Our inspector can recommend proper welding parameters and techniques to minimize spatter.
