Inspection course using DCVG and CIPS techniques with the use of state-of-the-art Voltab MC Miller digital equipment.
Objective
At the end of the course, the participant will be able to perform an inspection using the DCVG or CIPS techniques with the use of state-of-the-art digital equipment such as Voltab from MC Miller. Also, they will be able to identify and classify the status of the indications found according to their severity and corrosion behavior.
Audience
Professionals, technicians and engineering students with activities related to Industrial Maintenance, Quality Assurance and Control, External Corrosion and NDT inspection.
