Reinforced concrete structures often use the “seismic” grade of reinforcing bar 500E (to AS/NZS 4671). The designation “500E” means the reinforcing rebar must meet specific requirements in regards to mechanical properties to ensure the bar will have adequate performance under earthquake loading. The yield strength must be between 500 – 600MPa, the minimum elongation is…
Non Destructive Testing is a dynamic industry with a high degree of innovation. It includes a wide group of testing and analysis techniques to evaluate the properties of a material, component or system without causing damage. NDT is used in a variety of settings that covers a wide range of industrial activity, with new NDT…
2016 was a busy year for the NZ Welding Centre, with around 180 people attending our specialist courses and seminars for engineers, supervisors and welding inspectors. This month, 12 professionals complete their training programme in welding inspection leading to national and international qualifications: the CBIP Certified Welding Inspector (CWI), and the globally-recognised IIW International Welding…
A significant milestone for New Zealand structural steel industry has been achieved with the approval of the new standard AS/NZS 5131 Fabrication and Erection of Steel – released early this month. The need for this standard has arising out of concerns that product conformance does not meet the specified requirements in an increased global construction…
It was highly satisfying to be a part of the Pressure Equipment Workshop 2016 organised jointly by a dynamic industry committee composed of individuals from the PE industry and HERA. Nov302016 Over 100 people attended the workshop held last month at the Sudima Hotel in Auckland, and the concluding comment of a CEO of one of…
Structural steel hollow sections can be well suited to structural applications because they have a higher strength to weight ratio than open section profiles such as “I” beams and columns, channels or angles, and a lower area to be covered by a protective coating. Although they are more expensive than open section profiles on a…
The NZSSDA in cooperation with Stainless Structurals Asia Pte Ltd, and NZSSDA members Vulcan Steel and Rivet Ltd organised an expert seminar Laser-fused stainless steel sections – The structural solution. The seminar addressed architectural and structural applications of lased welded stainless steel sections and state-of-the-art fabrication practices. The event was presented by Kenny Lim Teck…
Over 100 representatives of the NZ pressure equipment community are coming together for the 2nd Pressure Equipment Workshop to share, discuss and debate issues that are of interest to the industry as a whole. Presentations will be given by industry people on a range of topics including fitness for service and risk assessment, application of…
The Steel Fabricator Certification (SFC) scheme continues to grow strongly with the latest group of three structural steel fabricators to achieve certification recognised at the Steel Construction New Zealand (SCNZ) AGM in Napier on 16 September. Since SFC’s introduction, 23 fabricators – representing 75 percent of New Zealand’s structural steel output – have become certified.…
HERA and the Pressure Equipment Workshop organising committee invite the pressure equipment community to the Second New Zealand Pressure Equipment Workshop 2016. The workshop is seen as benefiting designers, fabricators, inspectors, vendors, regulators, owners and operators. The goals for the workshop are: Sharing technical information, innovation and practical experiences Provide guidance and feedback; for the…
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…
We’d like to draw your attention to the following guides and resources available to you which are relevant to welding and local exhaust ventilation. Welding and local exhaust ventilation fact sheet Local exhaust ventilation (LEV) is an engineering control commonly used to control the risks to workers’ health from welding fumes. When designed, used…
