Abstract:

The purpose of this research project has been to investigate the feasibility of applying the Computerized Tomographic CT processes to the nondestructive testing and evaluation of weldments. The present study investigates the degree of spatial resolution obtainable via tomographic techniques as a function of the tomographic parameters. The scope of work has included a study of the applicability of CT processes for on-line quasi real time inspection of automated welding processes. The feasibility study included CT examinations of electron beam weldments on rocket motor casings, weldments, on a cast aluminum object, and several plate weldments. The main objective was to study the influence of the tomographic parameters on the resolution of the weldment features. A technique for rapid on-line, quasi real time inspection of weldments on a rocket motor casing is demonstrated. Tomographic evaluations were compared with available radiographic evaluations to study the relative merits of these techniques. The results of the present study have indicated the potential feasibility of applying CT techniques to the general area of weldments, including on-line inspection of automated welding processes.
