Current Leg at Weld CL
Note: Standard refracted angles: 45, 60, 70 degrees. Always verify refracted angle with IIW block before testing. Per AWS D1.1 and ASME V Article 4.
Reference
Half Skip = t x tan(angle)
Full Skip = 2 x t x tan(angle)
Sound Path (leg) = t / cos(angle)
Shear wave velocity in steel: ~0.1280 in/us
Leg determination based on probe index to weld CL distance.
