- aksss 5y agoNot a welder, but I'm aware of inspection procedures that use gauges to determine compliance with expected "shape" and consistency thereof. Also, x-ray imaging of welds and ultrasonic inspection of welds is a thing. You said "looks correct" and visual inspection is a thing but there are a lot of facets to that visual inspection that require some experience and tooling (e.g. magnifying glass, lighting, etc).
