This course will cover topics such as an introduction to weld repairs, differentiation in requirements between production and in-service-repairs, considerations for weld repair (including decision tree), qualification requirements, industry best practices, techniques for weld repair such as temper bead/controlled deposition repair, novel repair technologies such as taper stitch welding, repair methodologies for different types of failure mechanisms such as creep, SSCC, corrosion damage and clad repair. This course provides guidance on various types and methods of repairs to piping, pressure vessels, heat exchangers, and similar equipment.

By the end of this course delegates will learn about:

• • Understand the considerations to be applied before carrying out weld repairs
  • Prepare method statements and carry out qualifications
  • Apply industry best practice for weld repair
