  Making Sense of ISO 15608 – A Welder's Guide to Material Grouping If you've ever been involved in welding qualifications , you’ve probably heard of ISO 15608 . But what does it really mean in day-to-day welding work? Let’s break it down in simple terms. What is ISO 15608? ISO 15608 is a guideline that helps welding engineers, inspectors, and fabricators group different types of metals based on how similar they are when it comes to welding. Why group materials? Because not every metal welds the same way — and qualifying a welding procedure or a welder for each metal separately would be a nightmare. This standard saves time, money, and effort by grouping similar materials together so one qualification can cover many. Why It Matters Think of it like this — if a welder is qualified to weld one type of stainless steel, they might also be good to weld another similar one. ISO 15608 helps us prove that without having to redo the whole testing process. It’s widely used i...

  Weld Corrosion – Causes and Prevention - International Institute of Welding IIW - Free Talk online Weld Tech Talk    When: 12th July  (Saturday), 2025 at 17:00 (IST) Topic: Weld Corrosion – Causes and Prevention     This presentation will focus on ensuring that weldments (weld and HAZ) will be equally or more corrosion resistant than the parent plate, sheet, pipe, etc. While proper selection of filler metal is the obvious first step, there are many other factors that need to be considered, which if ignored, can lead to failure of weldments. Some of these factors can be controlled by the welding engineer, while others are in the control of the welder . We often learn best from mistakes, so cases where welding has gone wrong will be emphasized including suggestions how to prevent them from re-occurring.
