Description
Technical field
A kind of method that the present invention relates to friction stir plug repair welding, is specifically related to a kind of combined trigger-type friction stir plug soldering
Repair method and soldering set thereof.
Background technology
From Britain's institute of welding (TWI) since 1991 invention agitating friction welding technology (FSW), this technology because of
It has plurality of advantages in light-alloy connection area compared with traditional melt welding method, such as joint fatigue performance, draftability
Can be good, the weld defect such as postwelding residual stress and deformation is the least, crackle, pore can be avoided, and can significantly reduce simultaneously
Cost receives significant attention with saving the features such as material.But easily occur filling in the case of technological parameter or condition are unsuitable
Not exclusively, the defect such as lack of penetration and root is discontinuous, thus reduce Weld Performance.Equally, welding carries over after terminating
Keyhole produces " wooden pail effect " (i.e. stir friction welding seam keyhole and weld defect).It is used in engineering solving agitating friction weldering
The method of weld seam keyhole and weld defect mainly has: the weldering of melting welding completion method, pumpback formula agitating friction, friction plug weld and filling
Formula friction stir plug repair welding etc..
If carrying out repair welding keyhole with fusing process of intermediate, weldment contraction distortion causes precision not reach requirement.Meanwhile, can be formed after melting welding
The defect of pore, masks the advantage using agitating friction to weld this welding manner.Pumpback formula agitating friction soldering equipment complicated and
Costliness, backfill plastic metal is the most abundant, and effective thickness is thinning, eliminates the impact of keyhole defect the most thoroughly.Friction
Plug welding is actually consumptive material friction welding, is difficult to excellent mechanical property after repair welding.Filled type agitating friction welded
Cheng Zhong, the length of the half deflection type mixing needle that repair welding is used and tapering are more than keyhole diameter, utilize and by welding structure homogeneity
The plastic deformation of aluminium alloy mixing needle and flowing, it is achieved that the solid-state repair welding of butt welded seam keyhole.But this kind of method back needs
Supporter, is not particularly suited for the back structural member without supporter, such as hollow extrudate, tubular enclosed construction.In for
Empty or closed structure section bar agitating friction postwelding afterbody keyhole and the reparation of defect, there is presently no a kind of effective side
Method.
Summary of the invention
During the present invention is to solve existing agitating friction soldering weldering, bottom keyhole, easily occur that filling incomplete, crackle etc. lacks
Fall into, cause the problem that repair welding strength of joint reduces, be especially reparation and the benefit of keyhole of defect under hollow or non-matted state
Weldering provides a kind of combined trigger-type friction stir plug soldering repair method and soldering set thereof.
The combined trigger-type friction stir plug soldering repair method of the present invention, described method through the following steps that realize:
