A method for friction pressure welding a top workpiece to a bottom workpiece is provided. The method includes plunging a non-consumable refractory tool into the top workpiece with axial plunge pressure and rotational motion.

This inventive method is suitable for spot welding or continuous linear welding, and each workpiece can be comprised of similar or dissimilar materials. After the workpieces are joined, the refractory tool is retracted from the top workpiece. Control variables can include plunge depth, force, and rate of rotation, which can be readily optimized for different material combinations for sound joint formation.
