中文摘要	本发明公开了一种实现搅拌摩擦焊焊缝零减薄的焊具及焊接方法，属于搅拌摩擦焊领域。所述焊具由夹持体、轴肩和搅拌针所构成，轴肩的端面为内凹型,且在该内凹端面上加工有螺旋槽结构。采用该焊具进行搅拌摩擦焊接时，首先将焊具安装在焊机主轴上，将被焊母材放置于金属垫板上并牢固定位；然后启动焊机，焊具开始旋转并从起焊点扎入工件，当焊具轴肩端面的外边缘与工件上表面的距离为零时，焊具即停止下扎，随后焊具沿焊接轨迹行进来实施焊接，焊接中，焊具的倾角为0°。本发明解决了现有技术在消除搅拌摩擦焊焊缝减薄现象中存在的成本高、效率低、适用范围窄等问题。

英文摘要	The invention claims a method for realizing friction stir welding seam parts reduce the thickness of welding tool and welding method which belongs to stirring friction welding field. Said welding tool clamping body is composed of fillet and stirring needle formed by the shaft shoulder of the end surface is concave the concave end surface is set on the spiral groove is set on the structure of. Using the welding tool for friction stir welding welding tool is firstly installed on welder principal axis is welded on the base material is put in metal liner plate and firm location; Then starting welding machine welding tool begins to rotate and from the welding point is fallen in the work piece when the welding tool of shaft shoulder of the end face of the outer edge of the work piece on the surface of the distance as zero when welding it will stop under the chair then welding tool along the track running welding to perform welding is connected with the middle welding tool the inclined angle is 0 degree. The invention solves the problem that the existing technique it can eliminate the friction stir welding seam reduced the phenomenon that the cost is high the efficiency is low the scope of application is narrow and the problem that the.
