Brosey, W D; Dews, T W

An ultrasonic weld inspection has been developed for the girth weld of the aluminum substrate for a Kevlar-epoxy filament wound test specimen. The filament wound spheres are test coupons in a study to evaluate NDE techniques on a composite material with enclosed geometry. The girth weld of the aluminum substrate has been examined to ensure the weld is not a weak point in the coupon in which failure will initiate. Analog and B-scan data are combined to determine the presence of lack of penetration, suckback, protrusion, or porosity in the weld. The data are calibrated with a standard and then plotted as analog, B-scan, or color contour data as a function of angular position around the weld.
