Conference: Publication Date: 16 July 2012Testing Method:
Doosan Power Systems is manufacturing 1.0 inch (25mm) thick stainless vessels for a Customer in the UK. The seam welding of these large, PD5500 Category 1 vessels is carried out at site. The code calls for conventional film radiography as the volumetric NDT method. In 2009 the project identified that it required a large amount of radiography to be carried out on the butt welded sections. The welding process is Flux Core Arc Welding (FCAW) – see Figure 1. It was quickly identified that the site is congested with poor logistics for carrying out conventional radiography and close location to adjacent buildings
