DEVELOPMENT OF A NONDESTRUCTIVE INSPECTION METHOD FOR TITANIUM WELDMENTS.

Abstract

Work accomplished during the program to develop a nondestructive inspection method for titanium weldments is presented. The most successful method developed was neutron activation analysis for oxygen and carbon detection. A vacuum hot extraction method using an electron beam welder successfully differentiated uniformly contaminated screening specimens but was unable to detect single contaminated passes in a two inch weldment. The electron beam spike apparently damaged the weld as well. Temperature coefficient of resistance and ultrasonics inspection methods were eliminated after the screening phase of the program.
