00:00:12,701 --> 00:00:14,835
Hello, my name is Ghislain Morais

2
00:00:14,836 --> 00:00:17,696
and I am the product leader
of the eddy current

3
00:00:17,698 --> 00:00:21,066
and bond testing
division at Olympus NDT.

4
00:00:21,068 --> 00:00:23,470
Today we will demonstrate
how to perform

5
00:00:23,471 --> 00:00:27,951
a basic setup for the
Aerospace Bond Testing C-scan.

6
00:00:27,953 --> 00:00:30,683
We will use an OmniScan MX,

7
00:00:30,685 --> 00:00:32,738
an eddy current array module,

8
00:00:32,740 --> 00:00:34,656
a Bond Testing adaptor

9
00:00:34,658 --> 00:00:40,550
and a compact flash card with the MXB
software on it.

10
00:00:40,551 --> 00:00:43,940
For this demonstration
we will also use

11
00:00:43,941 --> 00:00:45,866
the Bond Testing hand-scanner probe

12
00:00:45,868 --> 00:00:48,368
and a calibration standard.

13
00:00:48,370 --> 00:00:50,381
Press the start button

14
00:00:50,383 --> 00:00:54,088
and wait for the
instrument to boot up.

15
00:00:54,090 --> 00:00:56,185
Once the instrument boots up

16
00:00:56,186 --> 00:01:02,655
select the MXB software
and wait for it to load.

17
00:01:02,656 --> 00:01:05,346
Plug the adaptor into the module

18
00:01:05,348 --> 00:01:08,721
and the instrument will
automatically detect it.

19
00:01:08,723 --> 00:01:11,841
Plug the probe into the adaptor.

20
00:01:11,843 --> 00:01:19,606
Plug in the encoder connector
and tighten both screws.

21
00:01:19,608 --> 00:01:22,080
Now we will start a basic

22
00:01:22,081 --> 00:01:25,511
Bond Testing C-scan setup
of the OmniScan.

23
00:01:25,513 --> 00:01:29,406
First, we need to
configure the encoder.

24
00:01:29,408 --> 00:01:33,085
To begin, press the blue menu button,

25
00:01:33,086 --> 00:01:36,871
then select "file"

26
00:01:36,873 --> 00:01:38,686
then select "open"

27
00:01:38,688 --> 00:01:41,998
then select the
"BT-default_Setup_file"

28
00:01:42,000 --> 00:01:48,475
and press OK.

29
00:01:48,476 --> 00:01:51,231
Now we will set the frequency.

30
00:01:51,233 --> 00:01:53,555
Note that different
material and defects

31
00:01:53,556 --> 00:01:56,308
may require different frequencies.

32
00:01:56,310 --> 00:02:00,243
For this demo we require
8 frequencies.

33
00:02:00,245 --> 00:02:02,810
Press the blue menu button,

34
00:02:02,811 --> 00:02:04,636
then select "wizard"

35
00:02:04,638 --> 00:02:07,050
then select "nbr. Freq."

36
00:02:07,051 --> 00:02:09,141
then set frequency amount to 8

37
00:02:09,143 --> 00:02:11,176
and press "OK."

38
00:02:11,178 --> 00:02:13,910
Now press start.

39
00:02:13,911 --> 00:02:19,406
For each frequency change
you must press OK.

40
00:02:19,408 --> 00:02:23,751
Set frequency 1 at 10 KHZ,

41
00:02:23,753 --> 00:02:27,693
frequency 2 at 12 khz,

42
00:02:27,695 --> 00:02:31,216
frequency 3 at 18 khz,

43
00:02:31,218 --> 00:02:34,285
and frequency 4 at 24 khz,

44
00:02:34,286 --> 00:02:37,860
and press "next"

45
00:02:37,861 --> 00:02:42,515
Set frequency 5 at 30 khz,

46
00:02:42,516 --> 00:02:47,220
frequency 6 at 36 khz,

47
00:02:47,221 --> 00:02:51,291
frequency 7 at 42 khz,

48
00:02:51,293 --> 00:02:54,206
and frequency 8 at 50 khz,

49
00:02:54,208 --> 00:03:03,286
and press "next" and "finish."

50
00:03:03,288 --> 00:03:07,801
Now we will balance
the probe in the air.

51
00:03:07,803 --> 00:03:11,485
Press the blue menu button,

52
00:03:11,486 --> 00:03:14,546
select "BT-settings"

53
00:03:14,548 --> 00:03:16,681
then "probe settings"

54
00:03:16,683 --> 00:03:20,468
and then press "balance (Air)"

55
00:03:20,470 --> 00:03:23,236
Now we will normalize the probe.

56
00:03:23,238 --> 00:03:27,358
Place probe on a defect-free
area of the standard.

57
00:03:27,360 --> 00:03:29,125
Press "normalize (part)"

58
00:03:29,126 --> 00:03:32,163
and immediately move the probe.

59
00:03:32,165 --> 00:03:34,215
Scan one row at a time.

60
00:03:34,216 --> 00:03:35,921
At the end of the row,

61
00:03:35,923 --> 00:03:37,695
push the blue button once

62
00:03:37,696 --> 00:03:41,293
and move the probe 0.25 in.(7 mm)

63
00:03:41,295 --> 00:03:43,288
in a perpendicular direction

64
00:03:43,290 --> 00:03:45,875
and then scan another row.

65
00:03:45,876 --> 00:03:49,663
The C-scan will appear row by row.

66
00:03:49,665 --> 00:03:54,550
Scan the entire calibration standard.

67
00:03:54,551 --> 00:03:58,663
Press "freeze" and the
C-scan image will change.

68
00:03:58,665 --> 00:04:01,050
Now that we have a full C-scan image

69
00:04:01,051 --> 00:04:03,818
we are ready for analysis.

70
00:04:03,820 --> 00:04:05,706
Press the blue menu button

71
00:04:05,708 --> 00:04:07,578
and select "display"

72
00:04:07,580 --> 00:04:11,266
then select "C-scan."

73
00:04:11,268 --> 00:04:13,105
Using "current frequency"

74
00:04:13,106 --> 00:04:14,931
and "C-scan component"

75
00:04:14,933 --> 00:04:19,296
allows you to adjust and
refine the c-scan image.

76
00:04:19,298 --> 00:04:23,428
Choose frequencies
1 through 8 in "amplitude" mode

77
00:04:23,430 --> 00:04:34,761
and also in "phase" mode
to obtain the best image quality.

78
00:04:34,763 --> 00:04:37,398
Usually disbonds give good results

79
00:04:37,400 --> 00:04:40,398
with low frequencies
in amplitude mode.

80
00:04:40,400 --> 00:04:42,486
Delaminations give good results

81
00:04:42,488 --> 00:04:46,856
with high frequencies in phase mode.

82
00:04:46,858 --> 00:04:49,846
You have just seen how the OmniScan MX

83
00:04:49,848 --> 00:04:53,583
now offers an improved
probability of flaw detection

84
00:04:53,585 --> 00:04:56,353
by using a C-scan image.

85
00:04:56,355 --> 00:04:58,620
This concludes the basic set-up

86
00:04:58,621 --> 00:05:01,733
for the Aerospace Bond-Testing C-scan.
