Ultrasonic scanning system for in-place inspection of brazed tube joints [PDF]
, 1973 A miniaturized ultrasonic scanning system for nondestructive in-place, non-immersion testing of brazed joints in stainless-steel tubing is described. The system is capable of scanning brazed tube joints, with limited clearance access, in 1/4 through 5/8 ...
