6.12: Bonded Joint
Inspection of Bonded Joints If the shape of a joint is favorable, ultrasonic inspection can be used to determine the soundness of joints bonded either adhesively or by any of the various metallurgical methods, including brazing and soldering. Both pulseecho and resonance techniques have been used to evaluate bond quality in brazed joints. A babbitted sleeve bearing is a typical part having a metallurgical bond that is ultrasonically inspected for flaws. The bond between babbitt and backing shell is inspected with a straight-beam pulse-echo technique, using a contacttype search unit applied to the outside of the steel shell. A small-diameter search unit is used to ensure adequate contact with the shell through the couplant. Before inspection, the outside of the steel shell and the inside of the cast babbitt liner are machined to a maximum surface roughness of 3.20 μm (125 μ in.) (but the liner is not machined to final thickness).
