Re: couplant on hot surface ----------- Start Original Message ----------- : is there everybody know, can we carry out UT on hot surface temperature about 800 degree celcius,what type of couplant used? ------------ End Original Message ------------
Hello What sort of UT do you want to perform defect detection (scanning) or spot thickness testing? This will govern what sort of couplant you will use. Do you have probes to perform these UT tasks?
Re: couplant on hot surface Depending on how much expense/hassle you want to go to, a laser-EMAT system (laser generator, EMAT reciever) can work at these temperatures, but it would be expensive and not very portable, so more geared to production line than on-site. No couplant would be required in that case.
