| Abstract Scope |
Spot butt friction stir welding of thin stainless steel sheets is proposed. The used material was 18%Cr-8%Ni stainless steel and thickness of the sheet was 0.1mm. In case of the thin metal sheet of such thickness, especially not overlap but butt joining, there are few previous researches. The difficulties are sheet rigidity, tool shape and tool position control. Because it is difficult to form the probe having complicated shape accurately, the semispherical shaped tool was used. The tool was rotated and moved to the position decided by the prescribed static pushing load. To avoid adhesion between sheets and a backing plate, a ceramic backing plate was selected. Effects of the tool rotation speed and the prescribed pushing load on weldability were examined. Only when the joining was successful, the characteristic load change by metallic adhesion between the tool and sheets was observed. |
