Welding of AA2124/SiC/25p-T4 by FSW at High Welding Speed and Monitoring the Process by Real-Time Control of Infrared Termography and Energy Consumption

Abstract:

The objective of this study is to present the feasibility of welding of AA2124/SiC/25p-T4 metal matrix composite at high welding speed by friction stir welding. We carried out the analysis of the microstructure, microhardness, and tensile test of welded sample from different areas, to evaluate the performance of the weld. The phase structure of AA2124/SiC/25p-T4 metal matrix composite was determined by X-ray diffraction (XRD). The temperature monitoring and measurements in the welding zone, in different areas was made, using infrared thermography to demonstrate that the FSW welds of AA2124/SiC/25p-T4 is below the melting temperature of the base material and to see the temperature distribution during the process. In addition, the monitoring and the control of energy consumption was achieved.
