Excellent lecture and you speak understandable english.🙂 I learned a lot from your presentation. The books we use here in the US are very similar to what you are instructing. I have struggled with the DAC, but you sir have opened my eyes. I did training in a tech center here in the US but the instructor, he really didn't present to my insight in to the DAC as you have..I am encouraged more so now by watching and listening, rewinding until I get the concepts clearly. Makes more sense now after watching your presentation. Much thanks sir for your hard work and experience. Bravo.
thank you for explanation, I was reading the text of how to use the DGS diagrams but I didn't understand now because of this video I know how it's works
Hi, we need to use the DGS curves still if the UT instrument has inbuilt DGS curves. Secondly, if we set back wall echo to 80% the db will come at 60 to 70. How to corelate with the hardcopy of DGS to instrument DGS. In your presentation, how 14db is assumed to set BW echo to 80%.
66db is required to bring indication echo to 80% of 600mm, whereas backwall echo required 14db to set 80% of 800mm. How it possible..Am in confusion..how 14db will taken to bring bwe to 80%
Great video, but how can I measure the material specific attenuation due to damping (ACV) for transversal probes? For example, when we use a V1/K1 block radius for calibrating a 45°, the attenuation due to beam spread I can check in the diagram, but how do I measure the ACV in a given material? Can I just connect two angle beams and use through transmission and calculate damping based on the soundpath between single and double skip?

It's DGS not DAC
@@hehehaha755 lol it's a typo
You are very welcome...
I'm from Canada but I'm doing my Ultrasonic 2 in German, you might have just saved my bacon, thank you.

Thank you very much for the kind words
Good Presentation, I did MUT 2 decade before as per Russian Spec DGS.
Thank you
Hello sir, can I speak with you
Thanks a lot for this precious course, We are waiting for the lower limit and how to distinguich small indication amplitude from a noise?
Will be coming soon - but next up will first be a video on TFM!

Muy bien explicado, gracias !!

Hi , is it possible get some point about the angle probe near field and beam divergent
Mi ídolo
pls do not lower your voice at the end of sentence like you were whispering because i could not hear and and understand what you are talking about.
