The recent series of “Welding Standards Update” seminars held in Auckland, Hamilton, New Plymouth, Palmerston North, Christchurch and Queenstown were a great success with more than 140 professionals attending the seminar series. Covering issues around welding and fabrication standards AS/NZS 1554.1:2014 Structural steel welding – Welding of steel structures and AS/NZS 5131:2016 Structural steelwork -…
The publication of AS/NZS ISO 9606.1:2017 Qualification testing of welders – Fusion welding – Part 1: Steels is seen as a move towards international best practice. And is a standard of significance, because it forms the basis of the next revision of AS/NZS 2980 expected to be published late February. For the many users of…
When steel merchants aren’t able to supply parent materials to a preferred AS or AS/NZS specification fabricators will face the need to weld structural steel manufactured to an overseas standard. This steel is often referred to as “alternative” steel or “not-prequalified” as it isn’t referenced in the welding standard AS/NZS 1554.1. While the standard allows…
Our Welding Centre General Manager Dr Michail Karpenko and Senior Welding Engineer Alan McClintock jumped the ditch to attend the International Institute of Welding 2016 Conference. Held in Melbourne in mid-July the IIW conference – is a fantastic global forum of professionals from around the world sharing and developing scientific and technical knowledge on welding…
HERA, SCNZ and the Institute of Welding are pleased to announce a one-day seminar on Design and Analysis of Welded Connections, which will be run throughout July and August in Hamilton, Auckland, Wellington, Christchurch and Queenstown. This seminar provides an overview of the theory of design of welded steel structures and components, with plenty of hands-on…
Over 80 IPENZ members took the opportunity at the April 2016 Auckland Branch Meeting to get up-to-date with current best practice in managing the quality of welding. Our Senior Welding Engineer Alan McClintock gave a presentation outlining what engineers need to be aware of when designing, specifying and managing the fabrication of welded steel structures.…
This month, the HERA Training Centre is again offering Part 2 of its training programme in welding inspection leading to national and international qualifications. This is for the CBIP Certified Welding Inspector (CWI), and the globally-recognised IIW International Welding Inspector Basic (IWI-B) and International Welding Inspector Standard (IWI-S). The Centre is New Zealand’s only International Institute of Welding (IIW) Accredited Training…
The risk of fire and explosion is ever present with welding and thermal cutting and the fatal accident at an Auckland tank farm is a timely reminder of this. It is no coincidence that most welding equipment and welding consumables come with warnings either in the user instructions or on the packaging. Nor is it…
For structural steel products to be free from serious problems in production and in service, it is necessary to provide a suitable level of quality management from the design phase, through material selection, into fabrication, and subsequently inspection. Requirements for welding/fabrication activities are given in the Code of Practice of the NZ Steel Fabricator Certification…
Flame, plasma and laser cutting are widely used in industry. The selection of the cutting process is based on the type of material, economic considerations and quality requirements. Despite some specifics, high quality results are obtainable using all of the cutting processes. The level of quality required for cut surface is determined by the application…
Weld access holes are frequently required in the fabrication of structural components. The geometry of these structural details can affect the components’ performance. The size and shape of beam copes and weld access holes can have a significant effect on the ease of depositing sound weld metal, the ability to conduct non-destructive examinations, and the…
