Art field.
Background technique
Agitating friction weldering is the new solid phase connecting method of one kind of Britain's institute of welding invention in 1991, and technique is certainly
It has just received extensive attention and has applied since invention.During agitating friction weldering, rubbed using high-speed rotating stirring-head with workpiece
Wiping heat production is plasticized materials to be welded locally, and when stirring-head is moved forward along weld interface, plastifying material rubs stirring-head
It wipes and rear portion is shifted to by the front of stirring-head under power effect, and form fine and close solid phase weld seam under the extruding of stirring-head.
Agitating friction welds compared with traditional melting welding, and heat input is low, and joint mechanical property is excellent, but in welding process
Due to parameter setting inaccuracy, as tool volume under pressure is inadequate and thermal weld stress not enough makes weld seam surface ditch dug with a plow defect occur.
Surface ditch dug with a plow is a kind of very serious Friction Stir Welding volume defect, can seriously affect the performance of connector.[Xu Aijie, Liu Ge
Flat, Li Chenggang waits agitating friction weldering defect repair welding process and performance evaluation [J] aerospace material technique, 2006,36 (z1):
93-95.] it reports and repairs trench defect with the method that agitating friction welds, when joint performance and single-run welding after secondary repair welding
For joint performance compared to not changing, welding deformation is small, and simple, convenient.Agitating friction weldering connects as a kind of novel solid phase
Connection technology can avoid generating stomata when melting welding is repaired, be mingled with and split because it is lower than fusing point with peak temperature in welding process
