| Outline of Final Research Achievements |
In this study, influence of the welding power source, the welding material and the shielding gas on the behavior of the arc plasma and the molten metal in gas metal arc welding process is numerically investigated to realize a high quality welding process. The results obtained shows that it is important to design the properties of the welding material depending on the properties of the welding power source and/or the shielding gas. Especially, the surface tension and the electrical conductivity are very important to determine the behavior of the arc plasma and the molten metal. There is a possibility to develop a guideline for controlling the welding process by using the results obtained in this study.
