Evidence stage
ConstraintFailure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
Tasks this bears on
Inspecting welds and fixing defects
Visual checks and measurements, preparing welds for testing, grinding out and re-welding defects, and signing off work against the procedure.
Being augmented✓ Evidence-backed
Where this applies
A US federal final rule for gas pipelines, now administered by PHMSA. It amended 49 CFR 192.241(a) to read that visual inspection of welding must be conducted by an individual qualified by appropriate training and experience; the preamble explains that the regulator judged the term 'individual' more suitable than 'person', a word the same regulations define to include companies. It binds gas pipeline operators, not all welding, and it ties the inspection, not the weld itself, to a qualified human; it does not measure how inspection is done in practice.
What this means
On gas pipelines the law has put a named, qualified human in front of every weld's visual inspection, and chose its words to make sure that means a person rather than a company or a system. Machines may weld; a qualified individual checks.
What it does not yet show
One US rule for one kind of pipeline; it does not show how inspection is done elsewhere or whether automated inspection is spreading.
What you can check
Open 69 FR 32886 (June 14, 2004) and find "Visual inspection of welding must be conducted by an individual qualified by appropriate training and experience".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
