摘要：
A new configuration of permanent magnet as a source of external magnetic field has been established to an autogenous tungsten inert gas (TIG) welding. The external magnetic field is generated by rectangle shape NdFeB permanent magnets of 260 mT and arranged in cups-type magnetic field (CMF). A charge-coupled device (CCD) is applied to monitor the phenomenon of the arc shape. The material used in this experiment is SS304 with a thickness of 2 mm. This study aims at investigating the effect of external magnetic field towards the arc shape and finding the configuration, which can reduce the power consumption and improve penetration. A significant effect on the improvement of welding efficiency can be achieved by using PR-NNSS-SD (50 or 70 mm), PP-NNSS-SD (70 or 90 mm), or PP-NSNS-Pull (50 mm). These configurations can reduce the power consumption up to 11%.
