International journal of production engineeringSummary: The purpose of this paper is to demonstrate the methodology in implementation of Six Sigma techniques and to make a suggestion for the process efficiency and productivity improvement in a TIG welding process in small scale fabrication industry. The importance of Six Sigma DMAIC (Define-Measure- Analyze-Improve-Control) methodology is illustrated in a well-defined structured manner which provides an agenda to recognize, calculate and eradicate sources of variation of issues to optimize the operation variables, progress and quality performance in a well control plans. In this work case study for fabricating refrigeration stand using TIG welding process and to improve the process performance (process yield) of the critical operational process, leading to better utilization of resources, and maintains consistent quality of the process and the associated output of the welding process where the existing system is intensely observed, classified, prioritized depending upon the basis of type of welding process, type of materials used, working timing of labor, work efficiency. In recent research papers the major works are concentrated on a particular issue as productivity and quality management of TIG welding process and ignoring the wider perception of process efficiency where there exists a necessity of having a detailed work to cover up all the issues, challenges associated with it. To overcome the problems in process efficiency a detailed, described and structured methodology of Six Sigma (DMAIC) techniques will be the right tool to provide suggestion for the improvement in process efficiency in TIG welding.

The purpose of this paper is to demonstrate the methodology in implementation of Six Sigma techniques and to make a suggestion for the process efficiency and productivity improvement in a TIG welding process in small scale fabrication industry. The importance of Six Sigma DMAIC (Define-Measure- Analyze-Improve-Control) methodology is illustrated in a well-defined structured manner which provides an agenda to recognize, calculate and eradicate sources of variation of issues to optimize the operation variables, progress and quality performance in a well control plans. In this work case study for fabricating refrigeration stand using TIG welding process and to improve the process performance (process yield) of the critical operational process, leading to better utilization of resources, and maintains consistent quality of the process and the associated output of the welding process where the existing system is intensely observed, classified, prioritized depending upon the basis of type of welding process, type of materials used, working timing of labor, work efficiency.
