Magnetic Particle Testing Level 1

Why attend this course:

Candidates will have the opportunity to use a large variety of equipment on welds, castings and wrought products on this theoretical and practical course. Suitable for beginners and personnel with existing NDT knowledge and PCN recognised, providing excellent preparation for Level 1 and 2 examinations. It meets the training hour requirements as specified by the relevant PCN documentation.

This is a course intended to supplement the MagneticParticle Testing Testing Pre-Approval courses prior to examination. This course is suitable for refresher training towards both the PCN and ASNT recertification examinations.
