Did you know that 💥 residual stress 💥 is a major reason why weld repairs of cracking often re-crack after a short time? Here's why. 💡 🔹 Weld metal shrinks as it cools. 🔹 Cracks are often in heavy rigid structures that create high restraint. 🔹 The result is very high tensile residual stresses in the repair weld. 🔹 These tensile residual stresses amplify service stresses and reduce fatigue life, plus acting to "tear open" small defects and create an initial crack. There is a simple solution to this problem. Inter-run Peening. Inter-run peening (when done properly) removes the shrinkage that causes residual stresses and/or distortion. A Weld-Hit is affordable enough and simple enough to use and maintain that it can be in every maintenance welders tool kit so that they can get awesome repair outcomes.

Are you manufacturing or repairing critical structural assets and need to do Weld Toe Burr Grinding as per the "IIW Recommendations for Improving the Fatigue Strength of Welded Joints"? If so, you should have a procedure for how to do it. The reality is that weld toe burr grinding isn't as simple as it sounds, and the guidance in the IIW document can be difficult, if not impossible, to successfully apply. WQMS have written a comprehensive yet practical procedure for Weld Toe Burr Grinding. It is written to be easily understood and applied by all stakeholders - Engineers, Supervisors, and Tradesmen. This procedure is written based on practical experience, not just theoretical concepts so you can start using it straight away and get the required results. You can purchase a copy of the "Weld Toe Burr Grinding Procedure for Fatigue Life Extension" directly from our website.

The power and importance of inspections and NDT data is underrated. It is the foundation of risk management and maintenance. The first step is to detect cracking. For HME (Heavy Mobile Equipment) this typically is a 90% visual inspection basis by looking for visible cracking, followed by MPI/ET to confirm, and UT for specialised inspections of pins/shafts and cracking from internal features. AINDT qualifications are typically mandated for NDT techs, but these are for individual test methods/processes. So why isn't there training for techs to visually identify and interpret fatigue cracking? The second step is to report and record the cracking. Nature and location are essential. But NDT reporting is stuck in the dark ages. Why is it that only crack length is reported? The simple answer is because traditional NDT reporting harks back to fabrication welding defects. It was never intended for inspections for fatigue cracking in HME. Better, more informative data is needed for risk management, scoping, planning and repair management. Location type, crack type, length, depth, material thickness are essential to know. If this makes sense to you too, then we can help. The Crack Data System (CDS) nomenclature is specifically designed for structural cracking inspections. It is simple yet powerful and provides the essential data needed by all stakeholders. It's been tried, tested and refined at some of Australia's biggest mine sites. It unlocks the ability to create standardised condition severity thresholds for TARP's, better planning and scoping, and easy welder competency management. Crack Data System is the master key for structural asset management. The CDS is open sourced to support industry as a new benchmark for inspection data reporting. WQMS provide cost effective online training for NDT techs for visual inspection of HME, Fatigue cracking identification and interpretation, and how to correctly apply the CDS nomenclature when reporting. WQMS also provide support for streamlined site implementation. #NDT #inspection #mining #maintenance #HME #crackrepairs #MEM #fatiguecracking #reliability

Congratulations to James Kannapinn, Josh Murphy, satish kumar and Peter Stubbs from WesTrac Cat -Mt Thorley branch, on being the first in the World to hold the MEM05069 Advanced Weld Repair and Maintenance unit of competency completed at Muswellbrook TAFE. They were also eligible and completed a Level 3 MWC competency, made possible by the strong alignment between the MEM05069 unit and the "Weld Australia award-winning" Maintenance Welder Competency micro-credential developed by WQMS. This significant achievement reflects their dedication to their studies and skills, as well as the support of their TAFE NSW teacher, Steven Hall, and their employer, WesTrac Cat. We are excited to see how they will use their new qualifications to make a positive impact in their roles and within the wider maintenance industry. #WesTrac #MWC #MaintenanceWelding #MWUP #MaintenanceWeldingUpskilling #MuswellbrookTAFE #ProfessionalDevelopment #SkilledTrades #WorldFirst #CertIVAdvancedWeldRepairandMaintenance #Mining #RepairWelding

Did you know that the benefits of peening are HUGE? ✅ Control Distortion ✅ Minimise Residual Stresses ✅ Maximise Fatigue Life Inter-run peening to minimise residual stresses is ESSENTIAL for any crack repairs. Otherwise the residual stresses induced by the repair welding will cause re-cracking to develop in a very short period no matter how good the weld is. HFMI (High Frequency Mechanical Impact) weld toe peening is scientifically proven and internationally recognised as the best way to maximise fatigue life of critical plant and structures. All the big equipment manufacturers use it, and it is used on bridges and cranes all over the world. There is even an IIW publication titled "IIW Recommendations for the HFMI Treatment for improving the fatigue strength of welded joints. Specialised tooling is required for inter-run and HFMI weld toe peening. There are many brands such as PITec, HiFit, Sonatest, UIT etc. Honestly, it doesn't matter what you use to do it - they all can deliver the same results. If you want peening equipment with more advanced features for quality control and ease of use for long periods, then we recommend PITEC Deutschland GmbH. But if you want a simple, robust and affordable solution that a welder can have in their tool kit, then choose Weld-Hit. It's the perfect tool for routine maintenance welding of crack repairs.

🎺 Big news! WQMS won the Training and Education - Organisation category in the NSW Weld Australia welding excellence awards. 🏆 🎉 This is in recognition of what WQMS has done to advance and improve the maintenance welding sector. Specifically, WQMS has achieved the following major milestones ⭐ Development of the Maintenance Welder Competency microcredential ⭐ Spearheading the development of MEM05069 Perform Advanced Weld Repairs and Maintenance as part of the Cert IV Engineering curriculum ⭐Delivering the Maintenance Welding Upskilling Program, funded by a Trade Pathways Innovation grant and working with Muswellbrook TAFE. MWUP was a novel pilot program for the delivery of a cluster of units based on MEM05069 and providing opportunity for upskilling ⭐ Designing and delivering a unique welder upskilling package for heavy equipment crack repairs. The training caters for welders of all abilities, ranging from welders new to heavy equipment maintenance welding to experienced maintenance welders. ⭐ Writing a comprehensive training resource package for MEM05069, including a 244 page learner guide ⭐Mapping the Maintenance Welder Competency (MWC)microcredential to a cluster of accredited VET units in the MEM package (based on MEM05069) so that the MWC provides evidence for the practical assessment components. Yet another industry first! ⭐Development of a world class eLearning and assessment package for MEM05069 and its prerequisites, fully mapped and RTO ready. #training #welding #upkskilling #maintenance_welding #maintenanceweldercompetency #mining #maintenance

Solidus Inspection and Quality Management Services (SIQ) shared some great photos of their Weld-Hit being used for inter-run #peening to prevent distortion and residual stresses. Inter-run peening is essential for repairs of fatigue cracking of heavy structures. Inter-run peening counteracts the weld metal shrinkage, neutralising the residual stresses that would otherwise form and dramatically reduce the fatigue life of the repair. Weld-Hit is a pneumatic #HFMI (High Frequency Mechanical Impact) tool used for inter-run peening and HFMI weld toe peening. WQMS supplies Weld-Hit kits with customised impact bit sets for fabrication and maintenance welding. See our website for all enquiries https://lnkd.in/eBxBN2ED

The sunsets are always something special in the Pilbara! WQMS recently provided advanced HFMI training and QC using the Weld-Hit for a valued client and major OEM as part of a fatigue life upgrade of an Ore Processing Plant.
