The Welding and Joining Processes Technical Group is introducing a Back-to-Basics series of webinars covering a range of topics relevant to welding and its associated activities.

Individual webinars will be discussing a variety of subjects such as how the metallurgy of metals affects their weldability and service performance, the applications and limitations of welding processes, design of welded joints, welding quality assurance and mechanical testing.

Who are the back-to-basics webinars aimed at?

  • those with little or no knowledge of welding technology
  • those just entering the welding industry
  • those wanting to gain an appreciation of the subject
  • engineers who feel the need for a refresher
  • anyone with an interest in welding

What is the format?

The webinars are informal with ample time for questions and will be around an hour in length, given by a highly qualified professional with extensive experience in the relevant subject.

Back-to-Basics: An Introduction to Steel Metallurgy

This first webinar will be covering:

  • some of the fundamental aspects of the metallurgy of carbon steel
  • a basic understanding of how a carbon steel achieves its required mechanical properties
  • the effects of varying cooling rates
  • all significant when we consider the parameters that need to be controlled during welding.

The webinar is aimed at those with little or no knowledge of metallurgy and will be kept as simple as possible with ample time for questions and for requesting clarification.
