INTRODUCTION

This course focuses on welding essentials that is required for practicing engineers, project leaders/managers, etc. those who have involved in onshore and offshore projects. It starts with providing an awareness of accidents case histories and current challenges in welding. Then, it presents welding physics, welding techniques and welding metallurgy. The welding metallurgy has been focused on steel and stainless steel. The course enables to acquire a better understanding about role of welding in design, construction, and operations (inspection & maintenance) phases. It also provides an overview of risk of welding failures and methods to minimize the risk of potential welding failures. Then, it describes the key characteristics of welding quality management and use of statistical principles and role of non-destructive testing (NDT). Finally, it presents the role of the skill of welders on welding quality, related parameters, and welding cost comparisons & calculations. Featuring industry case-studies and practical examples – the course covers the entire asset life cycle and addresses key stage issues with a view to optimize welded joints’ performance and quality. This course is considered not only for the engineers or project managers but for anyone who is working on onshore or offshore systems and who needs to be a professional player during the overall life cycle of a structural/mechanical system.

OBJECTIVES

  • Understand the role of welding in onshore and offshore over the life cycle.
  • Create awareness of welding physics, welding techniques, welding metallurgy, and welding cost calculations.
  • Obtain a better understanding about role of welding in design, construction, and operations (inspection & maintenance) phases.
  • Gain insight into risk of welding failures and methods to minimize the risk of potential welding failures.
  • Identify the key characteristics of welding quality management and use of statistical principles and role of non-destructive testing (NDT).
  • Experience the role of the skill of welders on welding quality, related parameters, and welding cost comparisons & calculations.
