Innovative Tool for Friction Stir Welding of Titanium Plates

The objective of the study was to analyze the level of wear of the tool made of sintered tungsten heavy sinter used for friction stir welding (FSW) of titanium alloys. The study includes an analysis of the microstructure of the tool, measurements of surface roughness, friction tests using 100Cr6 ball bearing and friction tests using a tungsten carbide WC. Based on the analysis of the presented results, it can be stated that the test material – pulled together with the titanium – will be characterized by high resistance to wear.
