want to ask something in UT-phased array

1. For acceptance/ reject the welds, are we
i)comparing the amplitude of a surface notch (code requirement)
or
ii)measuring the depth of root penetration.

2.Cause of insufficient root penetrant.
i)root Gap?
ii)Weld current?
iii)welding speed?
iv)or other reason

Hi,
You should consult the spec for calibration requirements. The incomplete penetration is most likely due to insufficient current, however, torch angle and travel speed can play a definite role in your problem.

NEW! The PragmaPro Instrument Platform

The PragmaPro is based on a modular cartridge technology and supports various NDT instrument modal
...
ities such as UT, PAUT, ECT and many more. This new platform is based on a machined, powder-coated aluminum frame for shock-proofness, best sealing qualities and maximum heat dissipation. This is practical to extend the outdoor temperature range and/or to extend the power injected in the transducers. The PragmaPro is aiming at a very wide range of applications, such as weld scanning, corrosion mapping and composite testing.
