A question for you UT guys,
We could be reducing a 6m length of s355 250/150?12.5 *6 to 240/150/12.5 (I don't know why they want to do this as we can get this in) How long would it take to UT a section of this?
It will be a single V on both sides.
I'm just looking for an approximate sort of time (give or take what ever probs/set
backs or hassle free) not pin point.

Re: UT Question My general rule-of-thumb is 1-2 ft/minute, so about 1/2 meter/minute. The 'gotcha!' is that indications take 5-15 minutes each. Thus the time is in the defects found, not the scanning time. I have found enough 'stuff' in 12 meters of weld to keep me busy all day.
If a full formal report of each defect is not required, only marking of the defects and depths, such that the welder can perform repairs, plan on 2-5 minutes per defect.
