| Abstract: |
Global and domestic competition related with welding and metal construction field is getting severe in Asia region. Then, low cost production with high weld quality is strongly demanded. These years, various fundamental researches have been conducted in not only universities/institutes but industries in order to develop high productivity welding and/or fully mechanized/robotic welding in Japan.
GMAW process is widely used in various production fields because it provides high deposition rate and/or it is suitable for automatic welding and robotic welding. The series of wire melting and subsequent molten drop transfer process makes deposition metal of butt weld and/or fillet weld. So, the stability of gas metal arc with metal transfer dominates the weld qualities and productivities. These technical issues have been promoting welding machine makers, consumable makers, gas-suppliers to improve and develop high performance welding processes. In this paper, current technologies related mainly with GMAW processes oriented to automatic welding in Japan are described.
