The Magnaflux method is utilized to identify cracks in crankshafts. At ‘Balu’ a 100% Crack testing is carried out on each & every product. The Magnaflux process utilizes an electrical current to produce magnetism in the part being checked. The crankshaft having been magnetized will expose any hidden cracks on the crankshaft & utilizing the ultraviolet light clearly shows the flow crack. The Magnaflux process is a critical step where many cracks would otherwise go unnoticed. The cracks present in crankshafts are often not visible to the naked eye.
