<p>The paper analyzes the problem of friction stir welding (FSW) technology. The mechanism of thermo-mechanical process of the FSW method has been identified and a correlation between the weld zone and its microstructure established. Presented are the basic analytical formulations for the definition of temperature fields. Analysis of influential parameters of welding FSW technology at the zone of the weld material and mechanical properties of the realized joint was performed. Influential welding parameters were defined based on tool geometry, technological parameters of processing and the axial load of tool. Specific problems with the FSW process are related to gaps (holes) left behind by a tool at the end of the process and inflexibility of welding regarding the degree of variation of material thickness. Numerical simulation of process welding FSW proceeding was carried out on the example of Aluminum Alloy (AA 2219) using the ANSYS Mechanical ADPL (Transient Thermal) software package. The defined was the temperature field in the welding process at specified time intervals.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.22.3.10022">http://dx.doi.org/10.5755/j01.ms.22.3.10022</a></p> |
