Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] like Figures 1 to 10 As shown, an ultrasonic thickness measurement method for metal composite materials uses dust, rust, dirt and other interface substances formed during the explosive composite process as the interlayer interface of two metal materials. Use the reflected wave of the ultrasonic wave at the interface between layers to record the propagation time of the ultrasonic wave in the single-layer material, and the sound velocity of the ultrasonic wave in each material to calculate the thickness of each material, and calculate the overall thickness of the composite material according to the thickness of each layer of material. It solves the problem that the reflected wave at the interface between layers cannot be effectively used. Using the interlayer interface reflection wave as the calculation basis for accurate measurement, the thickness of ...

Abstract

The invention aims to solve the problems that the thickness of each layer of metal of the metal composite material cannot be measured and the overall thickness of the metal composite material cannot be accurately measured in the prior art. The invention provides an ultrasonic thickness measurement method for a metal composite material. According to the method, using interlaminar interface substances mixed between adjacent materials of the composite material as interlaminar interfaces of two metal materials; recording the propagation time of the ultrasonic waves by taking the reflected waves ofthe interlayer interface as interface reflected waves during measurement; and calculating the thickness of each layer of material according to the echo time of the interlayer interface, summing the thicknesses of the layers of materials to obtain the total thickness of the metal composite material, and obtaining the thickness of each layer of material and the total thickness of the metal composite material by adopting the method.

Description

technical field [0001] The invention relates to the technical field of thickness measurement of metal composite materials, in particular to an ultrasonic thickness measurement method of metal composite materials and the application of interlayer interfaces in ultrasonic thickness measurement. Background technique [0002] The metal composite material is mainly a kind of metal composite steel plate made of carbon steel plate as the base layer and corrosion-resistant steel plate as the cladding layer. The carbon steel and the corrosion-resistant steel plate are formed into a firm metallurgical bond through explosive compounding or rolling compounding. The base layer is mainly It plays the role of bearing pressure, and the cladding layer mainly plays the role of anti-corrosion. Explosive metal composite materials are divided into double-layer metal composite materials and three-layer metal composite materials. Double-layer metal composite materials are the main ones, accounting...
