Area of interest in RT
(OP)
What is defined as the area of interest in RT? We have a pipe butt weld which has to be 100% xrayed. Per drawing upon fabrication an adjacent branch weld is encroaching upon the HAZ of the butt weld. Is it OK to perform RT by keeping the film just barely to cover the edge of the butt weld or does the Code require that xx inches on either side of a pipe butt weld should be covered during RT?

On a weld radiograph, the area of interest would include the weld and HAZ as shown on the radiographic image (film).

My question was intended to understand the area of interest in the weld radiograph. Does the Code say that the HAZ should be included? Can a second weld come near the HAZ an existing weld? In this case can the xray film capture both the butt weld and section of a fillet weld in close proximity? Will there be a conflict in proper interpretation?
