Non destructive testing is a common method of inspecting the surface and internal quality of the inspected parts without damaging the working condition of the workpiece or raw materials.It is a common method to ensure the quality of steel structure engineering.Due to different components,different non-destructive testing methods are used.Let's take a look at the introduction below.
Ultrasonic testing:A method of detecting defects in parts by utilizing the reflection characteristics at the interface edge when ultrasonic energy penetrates deep into metal materials and enters from one section to another.When the ultrasonic beam is transmitted from the surface of the part to the inside of the metal by the probe,it generates reflected waves on the defect and the bottom of the part respectively,forming a pulse waveform on the fluorescent screen.Based on these pulse waveforms,the location and size of defects can be determined.
X-ray inspection(X-rayγRadiation:A non-destructive testing method that uses radiation to penetrate internal objects in steel structure engineering and search for internal defects.
Magnetic particle testing:It is a testing method used to detect surface and near surface defects in ferromagnetic materials.When magnetizing a workpiece,if there are defects on the surface of the workpiece,an increase in magnetic resistance at the defect site will generate magnetic leakage,forming a local magnetic field.The magnetic powder will display the shape and position of the defect here,thus determining the existence of the defect.
You can roughly understand the various non-destructive testing methods commonly used in this type of steel structure engineering from the above explanation,which have good application effects in detecting engineering quality.The application of this method can not only ensure the progress of the project,but also improve the quality of steel structure engineering.
