![]() Hence, if you may be able to qualify one weld configuration using one mode only, you may need two or more mode to qualify complex weld geometry. ![]() Some modes are known to be more sensitive for specific flaw orientation. Hence the propagation mode selection is a major parameter for this new technique. The TFM algorithm would calculated the TFM image based on the selected mode velocity. Those PA parameters would probably be a mandatory variable as well for the FMC/TFM inspection. Because of that similarity, a lot of variable having an influence for the PA technique would have an impact over your FMC/TFM inspection, such as velocity, phased-array system, probe parameter, wedge parameter, Encoding device, scan parameter …. I cannot speak in the name of the standardisation organisation, but as a manufacturer we can certainly highlight some new variables that might have an impact over your inspection result.įirst, as you probably have noticed, the FMC data, could be acquired using Phased-array equipment. Re: FMC_TFM and Codes In Reply to ROBERTO OTERO at 16:56 May-15-2018 (Opening). I would like to hear the opinion of specialists and their experience in this regard.Įngineering, Sonatest, Canada, Joined Oct 2016, some "classic" calibrations would not make much sense in this type of obtained images. ![]() If I did not misunderstand some recently evaluated documents. what would be the process to comply with these requirements of the Codes?. The commercial equipment that has introduced these developments shows very good results in terms of resolution, etc.Īccording to different Codes (for example ASME), a series of parameters and / or essential variables are currently established that must be reported when using the PA technique. I refer to the processing TFM (Total Focusing Method) after an acquisition of data type FMC (Full Matrix Capture). ![]() Engineering, OMEGA SERVICIOS SPA, Chile, Joined Aug 2004,įortunately, other signal processing and algorithm options have been applied to obtain images focused almost entirely on commercial PA equipment. ![]()
