    1. MTSU & Industry Collaboration to Solve Welding Quality Problem Using DOE ABSTRACT TITLE: University and Industry Collaboration to Solve Welding Quality Problem Using Design of Experiments BACKGROUND: A local automotive seat supplier experienced a major quality problem in the fabrication of the metal seat frame used in the manufacture of the front bucket seats of automobiles. OBJECTIVE: Design a set of experiments to determine the effects of weld current, tip force, and weld time on the weld “break-away" METHODS: Run experiments using the Design of Experiments (DOE) methodology. RESULTS: DOE was successful and defects were eliminated. CONCLUSIONS: By collaborating with industry personnel at all levels, the student team was able to model the process successfully and provide setup boundaries for the operation of the welder. BACKGROUND This presentation covers the details of the Design of Experiments portion of a SIX SIGMA project that was successfully completed thanks to the collaborative efforts of both the industry and the university personnel.
