Testing Welded Tube

Testing Welded Tube MAC eddy current test systems are usually the preferred method for welded tube. Test systems can handle carbon steels, stainless alloys, copper, aluminum, titanium and all other non ferrous metals. Eddy current technology is most effective on tube with wall thickness up to 15 mm ( 5/ 83) and is particularly appropriate for finding many of the defects typical of the welding process. Full body tests using an encircling coil can handle tube up to 180 mm ( 7.23) . Weld zone only tests can be applied to small and large diameters, using sector coils.For more demanding test specifications, MAC provides ultrasonic test systems for full body or weld zone ( HAZ heat affected zone) inspection of welded tube. Generally, full body tests are conducted off the weld line on cut lengths. MAC ultrasonic rotaries house the transducers and couplant and can handle material up to 220mm.For tests on some small diameter tube, generally up to 75mm ( 33) , MAC UT rotaries can be installed on the weld line where they can operate at production line speeds.For larger diameters, usually testing HAZ only on line, MAC has worked with Reliant Technologies to provide mechanical handling, data acquisition, and irrigated transducer shoes that position the transducers and maintain coupling with the test material. MAC also has developed systems using alternative coupling methods, including bubblers and squirters. MAC FD-4 electronics can also be used to upgrade customer’ s existing immersion tank systems. Weld Types The process of ERW and Induction welding is preferred for most carbon and alloy steel. Defects that may arise include all of those previously mentioned. TIG welding is a slow process usually used for stainless steel or titanium. Incomplete ID weld defects are a common concern in this process. Laser welding is a much faster process used for stainless steel, titanium, duplex & nickel alloys. Typical defects include very short pinholes, and long continuous ID defects such as incomplete or miss-match welds. • 80 plus years of experience • Superior test systems • Knowledgeable fieldstaff • In or off-line NDT equipment • Eddy current • Ultrasonic • Flux leakage • Custom systems • Material Handling Distributor agent menjual service repair jasa perancangan perbaikan dan upgrade alat, sensor dan sistem Inspeksi eddy current test system, ultrasonic tester, flux leakage inspection system, Multiple & Custom NDT Systems: inspeksi quality check keretakan automotive parts for cracks, alloy, and heat treatment, bearing races for cracks, aluminum sheet for inclusions, US Army ordnance parts for cracks, rail testers ( M A Nordic) , dll.
