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. Author
