This invention belongs to the field of friction stir deposition additive manufacturing technology, and particularly relates to an apparatus and method for improving the interlayer bonding strength of friction stir additive manufacturing. A bar stock is fed into the main body through a bar stock feeding channel. A multi-stage flow-guiding section, with its gradually increasing height from the inside out, forms a gradient pressure field, causing the thermoplastic material to flow longitudinally. The flow-guiding fluids on the flow-guiding stages are sequentially arranged along the width direction through the flow-guiding blocks on them, generating directional shear force and guiding the material to spread orderly towards the outer edge. Circumferentially spaced flow-guiding balls fixed to the outer edge of the flow-guiding stages reduce flow resistance through rolling extrusion, promoting uniform material penetration to the lower interface. This solves the problems of radial splashing, circumferential backflow, and weak longitudinal penetration caused by insufficient material guiding mechanisms in traditional stirring heads. Through the synergistic effect of the gradient pressure field and the directional flow channel, the interlayer bonding strength is significantly improved, defects such as voids and cracks are avoided, and the fatigue life and service reliability of the additive component are enhanced.
