The purpose of this web site is to share technical information in the field of welding and welding related activities. It has no affiliation to any organisation or company
Welcome, My name is Steven Richards. I work as a Chartered Engineer involved in the design and commissioning of pressurised plant and equipment. I am also a registered European Welding Engineer. I have taken over this website from an retired work colleague whom some of you may know and I very much hope to be able to keep this site as informative as he did.
