Do you know the thickness of your car body steel plate and paint?

Measurement difficulties

The thickness of automobile steel plates and the thickness of car paint are both very important.

For conventional measurement method we need two different gauges. One type is paint thickness gauge, measured in micrometers, using magnetic reflection to measure coating thickness, with an error of about 1 to 2 micrometers. Another is ultrasonic thickness gauge, measured in millimeters, for metals without paint on the surface, such as steel plates, the thickness error is only about 1%.

But what we need to measure is steel with paint. Due to the different speed of ultrasonic propagation in steel and paint, the error is relatively large. Therefore, it is necessary to use an ultrasonic thickness gauge with a through coating function to through the paint layer and measure the true thickness of the steel.

Solution

Using YUSHI PM5 Gen2 ultrasonic thickness gauge, the coating mode with dual measurement options can measure the net thickness and coating thickness of workpieces with coatings or paint layers separately, and display them on the screen simultaneously. For those who need to measure the thickness of car steel plate and car paint at the same time, it is simple and convenient.

Other Applications

Steel structure technology has strict requirements on paint thickness. The type of paint, film thickness and anti-corrosion process determine the service life and life of the products it protects.

Applications like file cabinets, workbenches, basketball racks, etc. the above methods are very suitable for measuring the thickness of steel plates and paint layers simultaneously.
