The outer end of groove extends to first shaft shoulder, the outer rim of second shaft shoulder is open so as to be formed in the outer end of drainage trough.
Further, the width of described drainage trough from interior by gradually expanding outside.
Further, described drainage trough has some, and some drainage troughs are evenly distributed on first shaft shoulder and second
On the shaft shoulder.
Further, the drainage trough on first shaft shoulder is rotated clockwise by outer in, on second shaft shoulder
Drainage trough is by outside from interior counterclockwise rotates；Or the drainage trough on first shaft shoulder from interior counter clockwise direction by revolving outside
Turn, the drainage trough on second shaft shoulder is rotated clockwise by outer in.
Using the friction stir welding method of foregoing double-shaft shoulder stirring friction welding agitator head, two workpiece for first welding needs
After spelling, the mixing part of double-shaft shoulder stirring friction welding agitator head is directed at the edge joint position of two workpiece, then double-shaft shoulder agitating friction
Moved while welding stirring-head high-speed rotation so that edge joint position is squeezed into mixing part, and two workpiece clamps are in first shaft shoulder and second
Between the shaft shoulder, before making stirring-head by the frictional heat between the frictional heat between first shaft shoulder and workpiece, second shaft shoulder and workpiece
The material in face is plastically deformed, and then as the movement of double-shaft shoulder stirring friction welding agitator head, the material of plastic deformation is gradual
The behind of stirring-head is deposited on, so as to form stir friction welding seam.
The beneficial effects of the present invention are：Stirring-head has double-shaft shoulder（That is first shaft shoulder and second shaft shoulder）, stirred
Workpiece is sandwiched between first axle shoulder and second shaft shoulder when mixing friction welding (FW), it is not necessary to workpiece is strictly supported, therefore is applicable model
Enclose the welding for the irregular shape workpiece that is more extensively particularly suitable for use in.
