Abstract : The single transmitter/single receiver Delta Configuration will be the most suitable configuration for use in a manual weld inspection probe. Test results similar to those presented in this report could be obtained on any of the structural weldments (butt weld) observed during a recent survey of shipyard welding practices. The ultrasonic instrumentation, the weld surface preparation, and the accessibility of the weldments, noted during the survey, would be compatible with Delta weld inspection using a manual probe. Feasibility of tee weld inspection with the Delta Technique has been established; however, the test results reported in this phase of testing are preliminary and should not suggest an optimum test for tee configuration weldments. The success of the initial tee weld tests indicated, however, that a set of general parameters for Delta weld inspection has been determined and that application of these parameters to inspection of various weld configuration need only minor change or addition. The knowledge gained from the study of transmitter lens designs, oscillating search unit motions, and multi-search unit Delta Configurations should provide the data input necessary to optimize the Delta Technique for inspecting various weld configurations and thicknesses.
