Defect Location in Weld Inspection
It is important to determine the distance and depth of a located flaw or defect in a shear wave
test. A Sonic
®
Ultrasonic Calculator for Weld Inspection can be used to graphically locate
defects, or simple sine-cosine trigonometry can be used.
Direct Reflection Location of Flaws
1.Distance = sound path (as measured on EL/LCD) times the sine of the wedge angle.
Dist = S • sin(angle)
2.Depth = sound path (as measured on the EL/LCD) times the cosine of the wedge angle.
Depth = S • cos(angle)
3.
Example
:
A 60° wedge and EL/LCD measured sound path of 2 inches (refer to
Figure 5-44
).
Dist = 2 • sin 60° = 1.74 inches
and
Depth = 2 • cos 60° = 1.00 inches
