How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so you can combine the programme with your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is CIVA, Zetec UltraVision, WeldEye and Minitab, in free, academic or evaluation versions. Tests are studied on real procedures for phased array ultrasonic inspection, procedure qualification testing and digital radiography of joints. Assessment is continuous by module, plus the final integrated project.
Standards covered: ISO 3834-2:2021, ISO 15614-1:2017, ISO 5817:2023, ISO 9606-1:2017, ISO 17640:2018, ISO 9712:2021, ASME BPVC Section IX and AWS D1.1/D1.1M.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
