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