The welding technology is vitally involved from the conceptual and design stages right through to the end of life of a plant or equipment because welds have a critical effect on the production, economy, safety, and performance of such plants. It is a key enabling technology in thousands of Australian small and large manufacturing and operating companies, e.g., mining, processing, transport, maintenance,

Welding technology is not only important to the economic wellbeing of the nation. It is also important to our health, conservation of materials, and the sustainability of our environment.

Our aim is to help the Australian welding industry and develop a culture on safety, quality, productivity for sustainability.
