2018年8月5日 · Re: PAUT on Stainless Steel In Reply to ian at 10:54 Jun-12-2012 (Opening). As Sudheer said, SS welds can be successfully tested with Paut. The most important advandage is the signal to noise ratio improvment and the possibility to discriminate flaw indcation from background noise on b-scan or side and top view.

2016年8月16日 · PAUT Calibration Block. Greeting , I am in the process of start the PAUT on the piping weld joint to replace RT, basically pipe size range from 1 to 36 and all the size have the sch40,80,120and 160 plus some special thickness. I propose the pipe size for PAUT from 4 and above.I have both P1 and P8 material and some other special material also.

2022年1月5日 · Re: PAUT TCG calibration In Reply to Anmol Birring at 01:54 Dec-31-2021 . thanks Anmol. is there any solutions for it if we want to use 70 deg beam, except larger aperture, low frequency was used. also, in my opinion, 70 deg beam make no sense for thicker component, especially the 2nd leg (or full skip) was used, due to the small near field ...

2015年5月15日 · Re: PAUT Vs AUT In Reply to lohwinhoo at 03:20 Mar-28-2014 (Opening). PAUT can be set up for single welds or short runs and set-up and scan pattern chosen accordingly . AUT needs lots of preparation work, demonstrations, verification, the equipment and id only economical for medium to long runs of pipeline with same OD (wall thickness changes ...

2019年11月9日 · PAUT: A 64 channel probe is used with an aperture size of 12 elements. At 1mm pitch, this creates a 12mm X 7mm probe (84mm^2) or 594% larger square area than the duel element 6mm diameter probe. The backwall of the part will give a much higher amplitude signal than a point indication, as the gain required for reference will be low.

2020年12月18日 · Re: Paut ACCEPTANCE CRITERIA In Reply to Amir Khan at 04:51 Dec-17-2020 (Opening). Yes, water pipelines meet safety requirements more than normal requirements. ( As said by Mr.Ginzel sir, it's absolutely true, API related to petroleum products and welding procedure qualification also meet the same requirements.

2018年10月29日 · If good signal to noise ratio is evaluted for required sound path as you mentioned above, you can scan the weld.but with single pass PAUT on 50 mm pipe with 16 element aperture, resolution on root area and detection will be low( as the ASME CC 181 recomended also for thickness above 25 mm, more than 1 scan pass is required) .it is better to ...

2019年8月1日 · Re: PAUT In Reply to feriha irani at 11:33 Aug-01-2019 (Opening). Element pitch is the published value (usually 0.6mm or 1.0mm). Pitch (p) = Element width (e) + gap (g) If you want actual element width (e), you'll need to find the gap (g) value. A simple google search would have revealed this information, which was also discussed on this forum ...

2012年3月29日 · Re: PAUT & RT comparison In Reply to balwinder singh at 20:48 Mar-15-2012 . 10" curvature: I wonder why all the incompetent persons who has written the codes has decided that the limit for using flat probes or flat blocks is 20" (ASME) or 15 times the width of the footprint of the transducer (EN).

Test (PAUT) techniques, especially for extremes of detec tion and subtle defects considering manufacturing processes, while here we are focusing on wel ding process which is known as the most popular manufacturing processes. 2. Concerns and matters Welding processes have been under special considerations in recent decades. According to
