Sakthivael Kandaswaamy, doctoral student in Auburn University's Department of Industrial and Systems Engineering, will present "Thermal Field Mapping Technique for Friction Stir Welding Process" on Thursday, May 28, at 11:15 a.m. in 3210 Shelby Center. The lecture is hosted by the Department of Industrial and Systems Engineering and is the first in the department's summer seminar series.

Friction stir welding is a solid state "green" welding method developed by The Welding Institute in the United Kingdom. The model uses classic metal cutting theory to predict observed thermal fields. A friction stir welding tool passes through the material being welded by using an internal thermal mapping instrument that allows for symmetrical mapping of the thermal fields. This symmetrical mapping conclusively documents the asymmetrical nature of the heat sources within the friction stir welding process, which can successfully predict tool optimization and welding schedules while optimizing the mechanical properties of the weld.
