INTERNAL CONCAVITY Any length of IC is acceptable, provided the density of the radiographic image of the internal concavity does not exceed that of the thinnest adjacent parent material For areas that exceed the density of thethinnest adjacent parent material, the criteria for burn through are applicable
BURN - THROUGH
Maximum dimension of BT's image : unacceptable if it exceeds that of the thinnest adjacent parent metal.Maximum dimension of BT: 1/4" or 6mm
Maximum dimension is unacceptable if: it exceeds the thinner of the nonnal wall thickness joined, and the density
of the BT's image exceeds that of the thinnest adjacent parent material.The sum of the max dimensions of separate BBT's whose image density exceeds that of the thinnest adjacent parentmaterial exceeds 1/2 inch or 13mm in any continuous 12" length of weld or the total weld length(whichever is less)
