1 00:00:11,460 --> 00:00:13,593 Inspecting carbon steel welds 2 00:00:13,595 --> 00:00:17,863 with magnetic particles poses several problems, such as: 3 00:00:17,865 --> 00:00:19,656 The paint needs to be removed 4 00:00:19,658 --> 00:00:23,328 and extensive surface preparation is required. 5 00:00:23,330 --> 00:00:25,461 There are environmental concerns 6 00:00:25,463 --> 00:00:28,346 because of the harsh chemicals that are used. 7 00:00:28,348 --> 00:00:31,975 The process is highly susceptible to field conditions. 8 00:00:31,976 --> 00:00:34,455 There’s no permanent record of data. 9 00:00:34,456 --> 00:00:38,466 And it’s not well-suited for rope access inspections. 10 00:00:38,468 --> 00:00:41,015 The NORTEC 600 Weld Inspection Solution 11 00:00:41,016 --> 00:00:42,430 is an ideal replacement 12 00:00:42,431 --> 00:00:44,658 for magnetic particle inspection, 13 00:00:44,660 --> 00:00:47,058 it features several benefits such as: 14 00:00:47,060 --> 00:00:49,345 Inspection through paint or coatings 15 00:00:49,346 --> 00:00:51,900 measuring up to 2mm thick. 16 00:00:51,901 --> 00:00:53,700 It’s more environmentally friendly 17 00:00:53,701 --> 00:00:56,700 since no chemicals are involved. 18 00:00:56,701 --> 00:01:00,275 Evaluation of defect depth and length. 19 00:01:00,276 --> 00:01:02,858 Data reporting and archiving. 20 00:01:02,860 --> 00:01:05,740 And, it is rope-access ready. 21 00:01:05,741 --> 00:01:10,155 Inspection Through Paint 22 00:01:10,156 --> 00:01:11,731 Eddy current technology 23 00:01:11,733 --> 00:01:15,336 uses a magnetic field to couple the sensor to the part, 24 00:01:15,338 --> 00:01:17,048 so a certain distance between 25 00:01:17,050 --> 00:01:19,486 the probe and the part is permissible. 26 00:01:19,488 --> 00:01:22,865 That means that the NORTEC 600 Weld Inspection Solution 27 00:01:22,866 --> 00:01:26,418 can detect defects through up to 2mm of paint 28 00:01:26,420 --> 00:01:28,925 or nonconductive coatings. 29 00:01:28,926 --> 00:01:30,985 The ability to inspect through the paint 30 00:01:30,986 --> 00:01:34,323 or coatings makes removing these layers unnecessary. 31 00:01:34,325 --> 00:01:35,990 Eddy current technology 32 00:01:35,991 --> 00:01:38,985 also requires minimal surface preparation. 33 00:01:38,986 --> 00:01:42,021 As no chemicals are involved in the process, 34 00:01:42,023 --> 00:01:44,721 the NORTEC 600 Weld Inspection Solution 35 00:01:44,723 --> 00:01:48,168 contributes to a cleaner environment. 36 00:01:48,170 --> 00:01:52,493 Defect Depth and Length Evaluation 37 00:01:52,495 --> 00:01:55,170 The NORTEC 600 Weld Inspection Solution 38 00:01:55,171 --> 00:01:57,898 features unique tools that facilitate 39 00:01:57,900 --> 00:02:01,803 the evaluation of an indication’s depth and length. 40 00:02:01,805 --> 00:02:03,985 The depth of a surface-breaking indication 41 00:02:03,986 --> 00:02:07,198 can be evaluated based on the peak-to-peak amplitude 42 00:02:07,200 --> 00:02:09,703 in the impedance plane. 43 00:02:09,705 --> 00:02:13,163 Deeper indications produce larger amplitudes. 44 00:02:13,165 --> 00:02:14,766 The new real-time readings 45 00:02:14,768 --> 00:02:17,818 provide instantaneous amplitude and phase values 46 00:02:17,820 --> 00:02:19,640 that can be used for comparison 47 00:02:19,641 --> 00:02:21,511 with the calibration defects. 48 00:02:21,513 --> 00:02:23,211 This peak-to-peak measurement 49 00:02:23,213 --> 00:02:26,331 is a very reliable and consistent way 50 00:02:26,333 --> 00:02:28,575 to determine an indication’s depth 51 00:02:28,576 --> 00:02:30,948 because variations in the operating point 52 00:02:30,950 --> 00:02:42,966 have no effect on it. 53 00:02:42,968 --> 00:02:45,778 The NORTEC 600 Weld Inspection Solution 54 00:02:45,780 --> 00:02:48,798 also enables defect length evaluation. 55 00:02:48,800 --> 00:02:51,235 The length can be estimated based on 56 00:02:51,236 --> 00:02:55,235 the -6 dB threshold on each side of the flaw. 57 00:02:55,236 --> 00:02:57,731 The combination of the NORTEC 600 58 00:02:57,733 --> 00:02:59,081 real-time readings 59 00:02:59,083 --> 00:03:00,795 and instant reference signal 60 00:03:00,796 --> 00:03:14,105 make estimating an indication’s length extremely easy. 61 00:03:14,106 --> 00:03:18,566 Complete Archiving Solution 62 00:03:18,568 --> 00:03:22,626 Unlike MPI, recording inspection results is efficient 63 00:03:22,628 --> 00:03:26,070 with the NORTEC 600 Weld Inspection Solution. 64 00:03:26,071 --> 00:03:27,956 Files can be saved at any time 65 00:03:27,958 --> 00:03:29,496 during an inspection. 66 00:03:29,498 --> 00:03:31,500 Those files can be previewed on the instrument 67 00:03:31,501 --> 00:03:33,560 or downloaded to a computer 68 00:03:33,561 --> 00:03:35,628 where a full report can be easily produced 69 00:03:35,630 --> 00:03:39,783 in the NORTEC PC software. 70 00:03:39,785 --> 00:03:44,128 Rope-Access Ready 71 00:03:44,130 --> 00:03:47,700 The NORTEC 600 is ideal for rope-access inspection. 72 00:03:47,701 --> 00:03:50,401 It features a highly portable and rugged casing, 73 00:03:50,403 --> 00:03:51,785 4-point anchors, 74 00:03:51,786 --> 00:03:55,856 and its interface is also extremely intuitive. 75 00:03:55,858 --> 00:03:59,081 Olympus offers a wide selection of rugged weld probes 76 00:03:59,083 --> 00:04:03,416 and probe kits to suit your inspection needs. 77 00:04:03,418 --> 00:04:05,963 The NORTEC 600 Weld Inspection Solution 78 00:04:05,965 --> 00:04:09,451 is a major improvement over the MPI method. 79 00:04:09,453 --> 00:04:12,686 For more information on Olympus eddy current solutions, 80 00:04:12,688 --> 00:04:14,678 contact your local representative 81 00:04:14,680 --> 00:04:21,940
