When groove welds made by an individual welder are required to be tested, magnetic particle or dye penetrant testing may be used only in areas inaccessible to ultrasonic testing.

Retest all repaired areas. Submit weld inspection reports.

Testing frequency: Provide the following types and number of tests:

a. All full and partial penetration welds at the second floor framing level shall be checked 100 percent by radiographic or ultrasonic testing. At least 25 percent of the full penetration butt joints shall be checked by radiographic testing.

b. All full penetration welds at all cantilever beam moment connections in the project shall be checked by radiographic or ultrasonic testing, at least 25 percent of which will be checked by radiographic testing.

c. Of all other full and partial penetration welds, 25 percent shall be checked by radiographic or ultrasonic testing, at least 25 percent of which will be checked by radiographic testing.
