Ultrasonic Testing

Ultrasonic applications in the automotive industry are diverse, and include thickness measurement of wall thickness in cast engine blocks and cylinder bores, nodularity testing in crankshafts, steering arms, and other iron castings, gas barrier layer measurement in multilayer fuel tanks, as well as thickness of sheet metal (including reduction rate at bends), molded plastic parts, and rubber over belting in tires. All measurements are quick, reliable, and performed from one side of the test piece. Ultrasonic flaw detectors are commonly used for spot weld testing as well as inspection for porosity in engine blocks, crankshafts, and other castings.

Eddy Current Testing

Eddy current applications that have been developed for the automotive industry include the inspection of piston crowns, turbo discs and friction welded valves. Potential applications range from using eddy current arrays to detect cracking in pressings and components to using eddy currents to measure paint thickness.

Eddy current is also used in material segregation based on the Conductivity Measurements. The material sorting can be done based on Chemical composition, Heat Damage Detection, Case Depth Determination, Heat Treatment Monitoring.

Magnetic Particle Testing

Fluorscent Magnetic Particle Inspection is used to find Cracks on Forged Automobile Components before and after Machining.

It is used to find Longitudinal Seam Cracks in the Extruded Bars.

Remote Visual Inspection

It is possible to investigate a variety of problems without teardown using remote visual inspection, including checking engine internal component condition for carbon deposits and wear, pinpointing sources of unwanted noise, identifying corrosion and confirming component failure. Routine quality control inspections at the production stage are also frequently undertaken using remote visual inspection equipment - fuel injector nozzles, cast cylinder heads and turbocharger components can all be easily inspected using rigid or flexible instruments.
