Gas Metal Arc Fillet 용접 구조물의 최적화 공정을 위한 연구

A Experiment Study for the Optimal Process of Gas Metal Arc Fillet Welded Structures

GMA welding process is a production process to improve productivity for the provision of higher quality of material. These includs numerous process variables that could affect welding quality, productivity and cost savings. Recently, the welding part of construction equipment had frequent failure of major components in the welding part of each subsidiary material due to shock which is very poor according to the welding part. Therefore, the implementation of sound welding procedure is the most decisive factor for the reliability of construction machinery. The data generated through experimens conducted in this study has validated its effectiveness for the optimization of bead geometry and process variables is presented. The criteria to control the process parameters, to achieve a healthy bead geometry. This study has developed mathematical models and algorithms to predict or control the bead geometry in GMA fillet welding process.
