Abstract: A solid object is rotated in the central pool of molten metal that is formed by using an arc to melt a continuously fed metal wire and depositing the melted wire between the facing edges of two base metals to be joined. The stirring generated by the rotation in the pool moves hotter metal in the central region to its boundary adjacent to the facing edges. This stirring generated movement of molten metal is expected to better heat the facing edges so that the molten metal can better fuse with the facing edges. The stirring generated fluid flow within the molten pool also changes the solidification of the molten metal and the formation of the resultant grains.
