Abstract
The use of ultrasonic testing for the inspection of thick section weldments in titanium alloys requires careful acoustic characterization of the materials and weldments in question. In the present work ultrasonic wave velocity measurements were performed on a series of test specimens of titanium alloy weldments and base plate material. Data provided by x-ray diffraction analysis and scanning electron microscopy were correlated with the ultrasonic results.
Dissolved oxygen contamination during GTA and GMA welding of titanium alloys can result in severe embrittlement of the weld region. In order to evaluate the feasibility of ultrasonic testing for quantitatively detecting the presence of interstitial gas contamination in weldments of Ti-6211, ultrasonic wave velocity and ultrasonic attenuation measurements were performed on a series of five specimens with nominal oxygen levels of 0.07, 0.14, 0.20, 0.24 and 0.29 percent by weight. Density measurements, in addition to the ultrasonic wave velocity data, enabled relative determination of elastic moduli. Variations in the ultrasonic data were correlated with results from scanning electron microscopy and hardness testing.
