A DATA BANK FOR GRADED REFERENCE RADIOGRAPHS OF ALUMINUM WELDS

A set of graded reference radiographs of aluminum welds has been assembled. The set covers the thickness range from 9.5 to 19mm for aluminum in the 5000 and 6000 series alloys. The set includes five grades for three types of porosity, fine scattered, coarse scattered and linear; three grades of clustered porosity; two illustrations of inadequate penetration and tungsten inclusions and examples of longitudinal and transverse cracks, lack of fusion and undercut. This will serve as an interim set until a more formal graded reference radiograph document becomes available.
