NON-DESTRUCTIVE TEST WELDING. Quarterly Report No. 3, January-March 1962

Technical Report · Fri Apr 27 04:00:00 EST 1962

OSTI ID:4804336

The wrought steel blocks, 100-, 200-, and 300-mm thick, were examined in the same way as the rolled blocks, as described in report X 200/2/1962 (quarterly report No. 2). The 100-mm-thick block contains in the middle a zone of impurities, which can be used for examining these effects on the seam measurements in the test sample (rolled plate and wrought steel block). The 200- mm-thick wrought steel block contains a large amount of impurities in the marginal zones. As the rolled plate (thickness 200 mm), with which a welded test sample must be made, also contains impurities in the marginal zone, the 200mm- thick wrought steel block is not suited for further investigation. A new 200-mm block was ordered. The 300-mm-thick block contains practically no impurities. Several photographs were made of the test block by means of a sample of cobalt- 60, as described in report X 200/1/ 1962. Examination of these photographs revealed a need to cancel the effects of secondary radiations. Methods of accomplishing this are being studied. (auth)
