Abstract
The invention discloses a multi-layer forged and pressed stirring head for friction stir welding. The stirring head comprises a clamping part, a shaft shoulder part and a stirring needle, wherein theclamping part, the shaft shoulder part and the stirring needle are sequentially connected, a spiral groove is formed in the circumferential side of the stirring needle, and the top surface of the spiral groove forms a forged and pressed surface. The stirring head has the advantages that the structure is simple and reliable, the uniformity of welding seam tissues is improved, and the pressing amount and the thickness of a welding flange can be reduced.
