Introduction to Welding for O&M Staff

Posted in Courses


This training course is primarily intended for O&M staff working in thermal power and process plants, but could also be of interest to corporate engineering and management staff.  The objective is to give attendees an introduction to the world of welding and a basic understanding of the key elements involved in assuring weld quality during fabrication, installation and repair works.A range of topics relating to the design, processes, inspection and repair of welded joints on relevant components are treated using a combination of theory and numerous practical examples.  The examples are all based on actual project cases encountered by Tetra Engineering staff at plants around the world.
