Depending upon the use of the tubing as to whether these should be plugged at all. If there is a shift in climate then condensation will build up in the tubes and cause corrosion from the inside. Also there is a consideration for coating, if they are to be galvanized or painted.
If you have a "good" shearwave hand that understands what is going on then that should suffice. I have had many years at doing this. It all boils down to the calibration and EXPERIENCE.
Per API-1104 (20th ed)
5.4.2.2 Base metal -- A change in base material constitues an essential variable.
a. Specified minimum yield strength less than or equal to 42,000 psi.
b. Specified minimum yield strength greater than 42,000 psi but less than 65,000 psi.
From this statement the...
Volumetric examination is usually required for CJP (full penetration welds) on structural welding in lieu of X-ray. Part of the procedure to do a shearwave examination is to check the plate or structural member that is welded for lamination that could have propogated into the weld.

The only good that UT shearwave on a fillet weld is good for is to check the amount of penetration in the junction. I have used this many times to see how much penetration each leg has on very critical fillet welds.
Has anyone here heard a definition of "assistant welding inspectors"? I have heard of CWI and CAWI (associate) but not the term "assistant" at all. The particular specifications we are working to state "Inspection and quality of welds shall conform to the requirements of AWS D1.1. The weld...
Would this possibly go back to B16.11? I have the 1996 edition and Figure 2 on page 5 shows an example and the gap for fit up distance as 0.06". Am I understanding this correctly?
