Background of invention
Friction welding is used for many years in the welding industrial circle.For example, force together and will produce heat during simultaneously toward the rightabout rotation and cause the end plasticizing of pipe and combine when the end of two pipes.Stopping the pipe rotation fast can make two pipes fuse together.
On the other hand, friction stir weld is a kind of newer technology relatively, and it is elaborated in the U.S. Patent No. 5,460,317 of issue on October 24 nineteen ninety-five first.Friction stir weld is included in two workpiece and is in contact with one another a place a non-fus friction rabbling welding bonding tool that has the moulding sound end is pressed on two workpiece.When it was pressed on two workpiece, the periodic motion meeting of the sound end of instrument produced heat.The sound end of instrument enters or is inserted into the plasticized region that is generated by the sound end friction in two workpiece.Then sound end moves to the zone that two workpiece adjoin each other lentamente, thereby makes the zone between two pipes below the sound end to solidify together.
Friction stir weld has many good qualities.In friction stir weld, can not be exposed to combustion product comprising the material that is heated.This can reduce in the workpiece because the chemical change that the interface between workpiece and instrument and the byproduct thereof causes.Another advantage of friction stir weld is that can the not become temperature that produces with traditional welding processing of the temperature of workpiece is the same high, even also be like this in heat affected zone.This temperature that has reduced can weaken because the oxidation of the workpiece that ambient air causes, thereby has reduced the needs that inert atmosphere is provided at the place, welding position.
