UT inspection on UHMWPE weldments

Hello, I am looking for some assistance on performing UT inspection on Ultra High Molecular Weight PE weldments. We currently friction weld this plastic together but have no way of inspecting the weld integrity. We have samples out for microwave inspection which is not going well. It seems like the next best solution would be to use UT for the inspection. I have heard UT on plastics is iffy at best. Was looking for anyone with information on this or could provide me some direction on what works or best practices.

  • Kevin, I seam to remember Sonomatic did some work on UT of HDPE Pipe welds, that might be of help, Marc Stonehouse may be able to help. Is it single Frequency or swept frequency your trying, Robin Sloan has done some interesting things with the later.
