Magnetic Crack Detector Machine for Steel Bars
This Magnetic Crack Detector is a wet horizontal bench-type unidirectional machine that generates circular magnetization meant for checking both bright & black rolled steel round bars. Circular magnetization is achieved by clamping the bar directly between the headstock & tailstock and passing current through it. The machine is capable of detecting longitudinal cracks only. The headshot current can be switched between HWDC & AC for the detection of subsurface & surface cracks. The machine is semi-automatic in operation. All operations, such as loading, spraying, magnetization, demagnetization & unloading, are automatic. The only manual operation is the inspection.
The Magnetic Crack Detector machine has nylon rollers for placing & rotating the bar on the machine during the inspection.
Adjustable magnetization time of up to 2.0 seconds allows for the complete development of indications.
Available in various part lengths & diameter ranges.
The Magnetic Crack Detector machine is provided with a dark room frame, hood & curtains so that inspection with fluorescent inks can also be carried out.
