	Greetings. About the underlined text:

	Interesting, anyone know why they don't use better and more
precise methods like ultrasound or Xrays to find faults in welds.
If industry uses such technology then why doesn't the STS team?
Or am I missing the point - "visual inspection" IS those methods?

	It just seems to me that, from my _limited_ expirience, welds
tend to crack and waken on the INSIDE; not where a visual inspection
will catch them...

Anyone? Take care.
