Abstract
Official abstract text for this publication.
A tool driving section of a friction stir spot welding device is configured to cause each of a pin member and a shoulder member to advance and retract, and is controlled by a tool driving control section. A press-fit reference point setting section sets a position where the pin member or the shoulder member contacts an object to be welded as a press-fit reference point, and the tool driving control section controls the position of the pin member with respect to the shoulder member on the basis of the press-fit reference point, thereby controlling the press-fit depth of a rotating tool press-fitted from the surface of the object to be welded. This achieves the excellent welding quality at suitable precision according to welding conditions especially in a double-acting friction stir spot welding method.
First claim
Opening claim text (preview).
The invention claimed is: 1. A friction stir spot welding device configured to weld an object by partial stirring of a rotating tool, the device comprising: a cylindrical pin member as the rotating tool, the pin member being configured to rotate about an axis of the pin member and advance and retract along the axis; a tubular shoulder member configured to surround the pin member, rotate coaxially with the pin member, and advance and retract along the axis; a tool driving secti…
