Nondestructive Evaluation of Welding Crack Defects in Structural Component Of Track Crane Using Acoustic Emission Technique
On-line defects detection of structural component of track crane such as crane boom, outriggers, turntable and vehicle frame, is a difficult problem of nondestructive testing (NDT). In the present study, the usefulness of acoustic emission (AE) measurements for the detection of welding crack defects in the specimen made of HG70 steel, which is widely used for manufacturing structural component ...
متن کاملOnline Monitoring of Electron Beam Welding of TI6AL4V Alloy Through Acoustic Emission
Acoustic Emission (AE) Technique is the only Non Destructive Testing (NDT) method that can be thought of to be used as an online monitoring tool for detection, location and characterization of various kinds of active defects during any process. An effective approach of quality control is defect detection during welding process itself rather than by NDT of component after welding. Weld defects g...
متن کاملStudy of the Frictional Surface Damage Using Acoustic Emission Method
In this study, the change at rubbing surfaces has been investigated experimentally using an acoustic emission signal monitoring system. A steel ring is slipped on the surface of a metallic sheet to simulate frictional conditions. The mechanical disturbances caused by the movement of the ring produce stress waves propagating along the sheet surface. The out of plane displacement of the sheet su...
متن کاملFlexural monitoring of carbon fiber/epoxy composite by acoustic emission
Carbon / epoxy composite is one of the most useful polymer matrix composites that has special properties such as high strength-to-weight ratio, high hardness, high corrosion resistance, Resistance to nuclear radiation has high consumption in different industries such as aerospace industry. Therefor monitoring of loading of this type of composite is important. In order to determine failure mecha...
متن کاملAcoustic Emission and Signal Analysis
Acoustic emission (AE) is one of the most recent entries into the field of nondestructive evaluation. Due to the uniqueness of the basic principle and the potential for tackling a wide range of applications, the technique has gone through rapid strides in a very short time. Thus, today, two decades after the first application of the technique, AE is used in various industries, such as petro-che...
