Abstract：To enhance the stability of spot-welding process quality, import six sigma improving model, DMAIC. In the analysis phase, FMEA analysis was introduced to filter the key factors affecting the quality. In improvement stage, determine the best combination of factors with their best level by the implementation of orthogonal experiment. In the improvement and promotion stage, in order to maintain the results achieved and ensure staff analysis production status more scientific, established improvement and promotion processes, combined tools involved in the various stages of DMAIC and PDCA, and improvement measures were also normalized to the shop floor management system.
Key words：6σ；DMAIC；orthogonal experiment；FMEA
