THE INFLUENCE OF FRICTION STIR WELDED PROCESS PARAMETERS OF AA2519-T62 ON JOINT QUALITY DEFINED BY NON-DESTRUCTIVE LASER AMPLIFIED ULTRASONIC METHOD AND BY MICROSTRUCTURE ANALYSIS
Keywords:Friction Stir Welding, aluminum alloys, microstructure analysis, laser ultrasonic structuroscopy, non-destructive testing
The presented research contains a description of a non-destructive laser ultrasound internal structure analysis of aluminium joints made by friction stir welding. In the research, four selected technological parameter groups were taken into account. Modifications used in different parameter groups included changing tool traverse speeds and also its rotation speeds. The most important goal of this research was to determine the joint quality using a non-destructive laser amplified ultrasound method To verify obtained test results, an additional microstructural analysis was also conducted.
