Title Cognitive factors in the close visual and magnetic particle inspection of welds underwater
Bibliographic information June 1998, Vol.40, No.2, p.187-197. 24 ref.
Abstract In an experimental study of the accuracy of close visual inspection and magnetic particle inspection of underwater welds high error rates were observed. Performance was strongly correlated with embedded figures and visual search tests and was unrelated to length of professional diving experience, formal inspection qualifications or age. Cognitive tests of memory for designs, spatial relations, dotted outlines and block design failed to correlate with performance. Applications of this research include more reliable inspection reporting, increased effectiveness from current inspection techniques and directions for the refinement of subsea inspection equipment. Topics: cognitive performance; detection of faults; diving; inspection; magnetic testing; non-destructive testing; offshore oil extraction; underwater construction; visual tasks; welded joints.
