Magnetic Analysis Corp . Will be Featuring the Echomac ® WLD Ultrasonic Weld Line Test System
With operating conveniences for inspecting tube weld zones on-line during continuous production , the system is designed to test for longitudinally oriented defects that are typical of the ERW welding process . These systems are typically four channels , using both CW and CCW sound modes to detect ID and OD longitudinal defects between 5 % and 10 % of wall thickness . Additional channels can be added , depending on the application .
The WLD system includes MAC ’ s Echomac ® instrumentation , and a test head incorporating transducer assemblies with irrigated shoes for constant coupling with the tube being tested . Individual adjustment of each transducer to achieve the optimal position for CW and CCW direction is available . In addition a coupling alarm alerts the operator to any loss of coupling between a transducer and the tube , because of loss of water or improper alignment . Another convenience during operation is that individual irrigated transducer shoes can be easily exchanged to accommodate tube size changes in 5 seconds using MAC ’ s new quick disconnect mechanisms .
The WLD test head is supported by a strong gantry that allows operating on the weld line for mill testing , or off line for easy calibration for a new tube size . A precision roller assembly is located in the off-line position to allow for easy calibration of the transducers . Once the calibration is achieved , the test head is simply moved back to the on-line position for production line testing . The remote operator station contains essential controls , including remote weld following .

MAC ’ s Booth at Tube 2018 will also feature other instruments and systems , including the Echomac ® FD-6A instrument which holds GE Qualification for P3TF31 and P29TF82 Class A and B , typically required to meet high level quality standards for aerospace and other critical applications . MAC has recently supplied an Echomac ® FD-6A for inspecting titanium tube for nuclear applications . Echomac ® is compatible with rotary , immersion , bubbler or squirter and “ spin the tube ” type applications . The Echomac ® series is being used for a variety of applications ranging from full body testing of spinning tube and weld zone inspection during production , to 500mm Ultrasonic / Flux Leakage multi test systems for large diameter OCTG pipe .
