Ultrasonic digital electromagnetic ultrasonic steel tube、steel plate train axle online system

Currently ,domestic adopts piezoelectric ultrasonic detection ,it always need couplant to realize good coupling ,and surface quality is highly required,so it is hard to suitable for high temperature、high speed and rough surface, but electromagnetic ultrasonic solves this problem,it doesn't need couplant and detecting result is true reliable with high repeatability

Comparing to domestic piezoelectric ultrasonic detection ,electromagnetic ultrasonic probe has high coverage,probe number much reduced,mechanical structure is relatively simple,suitable for seamless steel tube，steel plates,train wheel and  wheel and axle online detection

Flow detection uses offline or online to detect surface of metal bar,tube,seamless tube,welded pipe and belt materials,near surface 、inner surface and inner flaw usually adopt outside wear probe,the detected material cross probe and detect;high frequency welded tube online vortex flaw detection can also adopt  saddle magnetic saturation、saddle probe to detect quality of welding line,including  lack of fusion、slag inclusion、sand hole、air hole、and other flaws.

When material area is big or shape is complex with high requirement,then it needs to adopt spot probe,manual or equipped with automatic scanning equipment to realize one by one scanning detection。

Different detecting ways need to adopt different auxiliary equipment,or suitable for situation,fully take advantage of current equipment of production scene ,design special auxiliary instrument to realize。for liquidity scene,usually adopt simple convenient auxiliary instrument to realize,manual way is available。
