Measurement of Cladding Thickness of Explosive Welded Austenitic Stainless Steel Clad Plate

In this paper, the ultrasound thickness measurement, the metallographic thickness measurement, the magnetic thickness measurement of the cladding of austenitic stainless steel clad plate for explosive welding is studied experimentally.The results show that the magnetic thickness measurement is not suitable for the field test of this material, which leads to the large deviation of the measurement results of the cladding thickness. Both ultrasonic thickness measurement and metallographic thickness measurement are suitable for thickness measurement of austenitic stainless steel.
