Abstract
Microstructure for resistance butt welding of super duplex stainless steel was investigated by means of transmission electron microscopy. The upset pressure and the welding time were changed and the resistance welding of super duplex stainless was done. As pressure and welding time increased, the absorbed energy was increased. The bonding interface was observed by TEM. As the pressure was increased, the oxide film was moving and new surface was welded.
