HERA recently commissioned an external market research company to figure out what NZ society thinks of our metals industry. The outcome was nothing short of interesting. Why? Because when asked if the steel industry was prepared for future technologies and innovation – only 47% felt we were. And of that, 79% responded that future-proofing the…
Last week was a successful one for our ‘Design for Joint Strength, Fatigue, and Fracture Resistances in Welded Connections’ seminars series. Taking place in Auckland, Wellington and Christchurch they were presented by University of Michigan Prof. Pingsha Dong. The inventor of the mesh-insensitive structural stress method adopted by the 2007 ASME Div 2 and API…

The seminars took place in Hamilton, Auckland, Wellington, Christchurch and Queenstown in July/August. Around 120 professionals attended the events, a record high for this series! Welded connections are subject to high levels of loadings in bridges and buildings in seismic zones, as well as in construction equipment, machinery etc. Achieving satisfactory performance in welded joints…
A regular enquiry received by HERA has been the application of fatigue design in steel bridges. On one hand, some designers have had trouble interpreting the current design rules; whilst on the other, many fabricators have expressed concerns on more expensive butt welds being specified for fatigue details where this might not be entirely necessary.…
According to EN 1090-2, steel components have to be identifiable and traceable throughout the whole production chain. The choice of identification method is not specified consistently in international rules and standards. In terms of durability and liability, markings should be resistant to particular fabrication processes such as sandblasting, hot-dip galvanizing or coating. The methods are…
