Solid-phase molding processing method

A solid-phase molding processing method, applied with a friction stir tool, wherein a lower end of the friction stir tool is provided with a tool head, the tool head comprises a stir body and a heating ring provided on the stir body, and the solid-phase molding processing method:

• heating the heating ring to generate heat, where the heating ring is heated to a heating temperature T sufficient to soften a to-be-processed workpiece while remaining lower than the deformation temperature of the tool head;
• wherein the heat generated by the heating ring is conducted downwardly through the stir body to a shaft shoulder and/or a welding pin of the tool head;
• driving the friction stir tool to rotate causing the to-be-processed workpiece undergo deformation and generating friction heat;
• converging the friction heat with the heat conducted to the shaft shoulder and/or the welding pin of the tool head to heat and soften the to-be-processed workpiece and to form a plastic deformation flow;
• and
• translating the friction stir tool to make the plastic deformation flow deposited behind the tool head to form a molding portion.
