In response to the specific requirements and needs of establishing and operating concentrated solar power (CSP) plants, Afrox has developed a comprehensive product and energy solutions offering to specifically suit the industry. African Fusion talks to Johan Pieterse, Afrox's business manager for the manufacturing industries.
On a 1 100 ha site near Pofadder in the Northern Cape, the 100 MW KaXu Solar One concentrated solar power (CSP) plant has now been commissioned. It is the first CSP plant in South Africa to use parabolic trough technology. Following close on its heels are Khi Solar One, a 50 MW power tower CSP plant outside Uppington, and the 50 MW Bokpoort solar parabolic trough CSP plant, which is nearing completion.
Publication of our March edition of African Fusion marks the end of the first quarter of 2015 – and it's been a tough one with significant movement in the welding fabrication industry in South Africa. Most notably, Jim Guild has retired as executive director leaving Sean Blake in charge of the Institute. We wish Sean well and are confident that he will lead the Institute successfully.
Our SAIW news pages for this issue open with the Young Welder of the Year competition, which has been won by Steinmüller apprentice, Jaco van Deventer. The 2015 competition was the largest ever and the quality of the young welders continues to improve.
Our lead SAIW feature this month comes from Albrecht Hans' EN 15085 seminars that SAIW hosted in Johannesburg and Durban. We report on this important standard for local manufacturers involved in the welding of railway vehicles and components.
The 2015 Young Welder of the Year is almost upon us, and African Fusion talks to Houston Isaacs, the 2013 winner and 2010 runner up about his experienced and subsequent successes.
The SAIW has also assisted the University of the Witwatersrand's School of Chemical and Metallurgical Engineering with peripheral equipment for its R13.5-million Gleeble thermal-mechanical simulation facility. Wit's University's Tony Paterson tells us about this high-tech machine.
The first paper in this issue is by Prince NSP Dlamini, who was awarded the SAIW's 2014 Harvey Shacklock Gold Medal in August this year. Through case studies, Dlamini highlights some of the technical challenges associated with the materials, welding and weld quality for the new-build power stations.
Our SAIW news section opens with the Institute's 66th Annual Awards Dinner, which was held at the Gold Reef City Conference Centre on Friday August 15. Compèred by cabaret artist and comedienne, Irit Noble with additional entertainment by music group, the Delivery Boys, some 350 SAIW and welding industry stakeholders celebrated the industries 2013/2014 successes.
Then, in an article entitled ‘SA's fabrication can emulate Korea's success' Sean Blake discusses Korea's welding and fabrication success and suggests that South Africa, like Korea, should build an economy around fabrication.
Our company profile is form ND Engineering, a particularly impressive Durban-based fabricator. We visit the company's Queensburgh fabrication workshops and talk to Elvis Green, the current owner and MD, and Mark Ackerman, GM. This article is the ‘must read' in this edition.
This issue features two technical papers from IIW's 67th International Assembly and Conference held in Seoul, South Korea during July. The first explores the post weld heat treatment (PWHT) requirements of modified Grade 91 steels, while the second outlines a novel tri-arc dual wire method for high deposition low heat input welding. The full list of references for "A tri-arc dual wire method for high deposition low heat input welding" by Zheng Geng , Zhanjing Wei, Xuefei Han, Qinghua Wang, Wei Wang, Guang Qiu can be downloaded here.
This issue of African Fusion has as fresh look. We hope you like it, but feel free to comment. The content, of course, remains but we have had another go at strengthening the inspection and NDT component, which is one of the Institute's strengths.
Opening the magazine, you will notice an SAIW section, branded with their red and blue colours and the ‘flash' emblem in the page corners. These pages are dedicated to articles and of SAIW-related events and news.
In this issue we open with the SAIW's intention to support EN 15085 for welded railway vehicles, a railway manufacturing code that will almost certainly be required by local manufacturers wishing to participate in the PRASA and Transnet rejuvenation programmes. Harold Jansen, SAIW's NDT manager, follows this with a piece about the role of NDT Level 3 Inspectors. Following a survey, Jansen clearly identifies the advantages of using Level 3 Inspectors in industry, even though their use is not directly mandated.
Welcome to the first issue of African Fusion for 2014.
Our opening feature in the SAIW News section of the magazine comes from SASSDA's recently hosted duplex stainless steel seminars in Cape Town, Durban and Johannesburg. We present presents a summary the welding-related opening sessions.
This issue's company profile is about Genrec, one of the largest structural steel engineering companies in Africa. We talk to Michael Mamotte, the company's marketing and new business development manager.
Both the papers come from the Essen IIW Congress and Conference held in Essen in 2013. First, A Burt, C Fink and D Mundersbach present work on surface overlay cladding using a dc TIG process with ac hotwire, while their colleague, P Kuebler from Rocklea, Queensland presents some examples of sustainable, innovative and automated welding and cutting applications from Australia.
Welcome to the final issue of African Fusion for 2013.
Our opening article in the SAIW news section of the magazine is from one of the evening meetings at the Institute's City West premises. Shelton Zichawo, quality systems assessor for SAIW Certification outlined, very clearly and succinctly, the requirements for those wishing to implement ISO 3834. This is a must read for anyone about to embark on the process and a must circulate for welding quality professionals needing to convince administrators to go this route.
The featured paper: Laser metal deposition microstructure of modified low-C martensitic stainless steel, was presented by research stalwarts, Corney van Rooyen and Herman Burger of the National Laser Centre and Madeleine du Toit of the University of Pretoria at the SAIW-hosted IIW Regional Congress and Conference of November 2012 - and won the SAIW Harvey Shacklock Gold medal for its authors.
The SAIW has had a busy few months, culminating in the 65th Annual Dinner and Awards evening on August 16. Congratulations to the top students: Charl Brazelle and Khutso Moahloli; to the Shacklock Gold Medal award winners for research, Corney van Rooyen, Herman Burger and SAIW president Madeleine du Toit; and to Steinmüller Africa on being awarded the SAIW Gold Medal.
We feature Steinmüller Africa in our company profile this issue. With the Medupi unit 6 delay, it is not so easy to find ‘uncontaminated' good news among the contracting fabricators, but Steinmüller Africa certainly bucks the trend, for all the reasons identified by the SAIW in its award citation: its commitment to training at the highest levels; to investing in and applying modern technology; and to the implementation of welding quality standards, most notably ISO 3834.
The new SAIW Materials Testing Laboratory is now up and running at the Institutes' Johannesburg West facilities. It completes the comprehensive technical services offering available through Sean Blake and his team. In the opening article of this issue, we look at the testing equipment in the laboratory, its capabilities and the implications for SAIW and the welding industry.
Also featured in the front of the magazine is the SAIW- and SASSDA-hosted seminar by Damian Kotecki. While it is impossible to cover all of a valuable seminar like this as a magazine article, we hope we have done justice to the opening session on martensitic stainless steels.
Our company profile this month is a long one because it profiles three companies within the Tubular Holdings Group. We visit Tubular Structural Engineering (TSE) and Tubular General Fabricators (TGF) in Witbank and Abeyla Trading, the pipe and tube specialist. The Group is involved on our power station new-builds and has made a massive contribution towards the air-cooled condenser structures.
WELCOME TO THE FIRST OF ISSUE OF AFRICAN FUSION FOR 2013.
The year opened early for the SAIW with preparations for the 2013 Young Welder of the Year Competition that was held during the last week of January. Houston Isaacs, last year's runner up - and a graduate of the West Midlands College, one of the IIW approved welder training institution - was the emphatic overall winner, having outscored the other competitors for all material types. Shandre Janse van Rensburg, another West Coast College graduate, was runner up.
The competition is getting better and better every year, boding well for our ability to attract and train new welders in South Africa.
