The paper provides an in-depth analysis of the impact of the updates to the EN ISO 9712 standard on the training and certification of non-destructive testing (NDT) personnel

and it discusses strategies for addressing these changes. The revised standard has made adjustments in terms of training hours

industrial experience

visual acuity requirements

examination criteria

and extension procedures. It places a greater emphasis on practical operational capabilities

lowers some entry barriers for certification

and introduces a structured credit system assessment as a means for extensions

encouraging certified personnel to continue learning and improving. Taking the Harbin Welding Technology Training Center of the machinery industry as an example

its innovative measures such as small-class teaching

specialized training

exchange of new technologies

and on-site services to enterprises have effectively improved the training outcomes for students. This enables them to better meet the needs of enterprises

provides strong talent support for the global reach of “Made in China”

and promotes the improvement of domestic welding manufacturing technology levels.
