Reduction Analysis of Welding Defects using Lean Six Sigma and DMAIC Application – A Case Study

This research aims to investigate the process of gas tungsten arc welding commonly used in submersible pump industry. The weld abandons is a noteworthy concern prompting revamp, greater expenses, and this manner, influencing conveyance plan activity. article succeeds deploying six sigma Define, Measure, Analyze, Improve, Control (DMAIC) structure improve action features assess eradicate different sources an operational system referred To implement fundamental methods various tasks, best usage instigation availabilities, variabilities moderations, maintaining consistent output tool adopted. root cause analysis Tungsten Inert Gas (TIG) defects static tools recognize potential causes for controlling supporting few changes with proposals are specified. current level deformity was found be 15% stator rejections period one month. After implementing proposal, overall defect expected reduce.
