Stress & Strain: When to Use Microhardness, Stress Relief, and Heat Treating in Mechanical Testing
In welding and fabrication, the quality of your finished product depends on more than just a clean weld bead. Beneath the surface, invisible stress, hardness variations, and microstructural changes can weaken performance. That’s where mechanical testing becomes essential. Mechanical testing methods like microhardness, post-weld heat treatment (PWHT), stress relief, and induction heating are used to…

Why Metallurgical Testing Matters: The Hidden Costs of Welding Non‑Compliance
When most people think about welding, they picture sparks flying and metal fusing under heat. But behind every weld lies something even more important: metallurgical testing. It’s not just about checking boxes for compliance—it’s about protecting your people, your assets, and your bottom line. So, what happens when testing gets overlooked? Let’s take a closer…

What Is Forensic Welding
When welds fail, the consequences can be severe—leading to costly repairs, legal disputes, and even catastrophic structural failures. That’s where forensic welding comes in. This specialized field of metallurgy and engineering focuses on investigating and determining the causes behind weld and metal failures. Whether used in court cases or to improve future welding practices, forensic…
