THE USE OF QUALITY TOOLS TO MITIGATE THE SUBMERGED ARC WELDING PROBLEMS INCREASING THEIR QUALITY

Abstract

The submerged arc welding is one of the processes most commonly used in welding, but as all processes are subject to problems, through a descriptive methodology, qualitative, with application in a case study, we used some quality tools (flowchart, brainstorming, Pareto, 5W2H's) to accurately identify some points where there are opportunities for improvement, and can mitigate them increasing product quality and also the qualification of manpower in the industry. Problems were identified in the production process, such as the lack of standardization in speed and form used in the welding process and incorrect application of electric current. For these cases, they were also suggested in his mother's 5W2H training and periodic refresher for everyone involved in each step of the process and also the development of Standardized Work Instructions for each identified step.
