This document summarizes a presentation on C-scan ultrasonic non-destructive testing and a shearing fixture for brazed joints. It describes how C-scan uses ultrasound to detect flaws in brazed joints by producing a 2D image of the bonding interface. It explains the principles of pulse-echo techniques used in C-scan. It also describes how a shearing fixture was designed to test the shear strength of brazed joints, noting the advantages of using a fixture over other testing methods. Confirmation of test results is done through milling and mechanical tests that are compared to previous C-scan and bonding percentage measurements.
