Practical of Ultrasonic Testing Procedure
Музыка
Hi Guys,
I am back with another video and this video is on the Ultrasonic testing of welding joints.
If I describe ultrasonic testing in simple words the Ultrasonic testing technology is basically based on the ability of high-frequency oscillations (about 20,000 Hz) to propagate into the metal and be reflected from surface scratches, voids, and other discontinuities. The artificially created and the directed diagnostic wave enters into the tested material and in the case of a defect deviates from its normal propagation. The nature of the defect can be recognized by graphical and parametric readings.
I hope you will like this video and if you like this video then press the like button, share the video and subscribe.

Superb ut scanned 👌
Well done Mr Arun Sr and ranjeet ..really very nice video and very helpful for upcoming QA/QC engineers .
Nice video
Mistakes during UT overlapping and scanning speed
Where is DAC , First mark half n full skip distance Then check lamination then go for scanning. .
Sprrr
Agar job thickness Mera 8mm se Kam hoga to jab repair ayega usme ut krne ka kya cretia hai asme section 5 me ut karna padega ya jarurat nhi hai please reply

Sir, pipe thickness 6.4 mm, dia 4".ut testing half skip catch one defect sir, but defect beam bath full beambath is coming, why is this happening, sir 70 degree probe use sir true angle 69 degree, but defect half skip and depth ok sir but beam bath only high full beam bath coming sir. Why sir. Please tell me sir
Very useful video sir. Please upload more video
Scanning is too poor, AWS not recommend 8x9 mm size probe. UT technician is not well
Sir, When scanning a weld in 10mm plate using 45degree probe. Range is 125. Machine shows SP=43.5, SD=30.7,D= 30.7. How can I calculate where is deffect??? Sir please help..

45 degree probe for job thickness above 45 mm
Interesting VIDEO! One candidate (UT LEVEL2)I would like to join in as UT inspector kindly give me a feed back

How can I help you?
Scan pattern aren’t overlapping, could use some improvement
Probe to achhe she chalawoo 😅😅😅
Hallo sir is joints me UT ka kon sa acceptance criteria use hoga

This is AWS bro 😂 in AWS no DAC curve reference dB is only going to calibrate and scanning dB need to set as per sound path
Scanning karne nahi aa raha hai bhai apko
Mujhe qc engineering ka number chahiye
Ye welding galat procedure se weld Kiya yai..... flange and web Ka joint in line (ek line )weld nhi hota
How much overlap you taken , too blender mistake you did probe scanning movement is very poor , please scan 10%overlap i.e and one thing you must scan 100mm skip distance you doing 50mm skip distance only , and probe scanning speed 150mm/sec only you are doing too fast . So please be careful about scanning .
Scanning was not good
