Description
Technical field
The utility model relates to the device of a kind of laser-assisted agitating friction seam weldering, belongs to metal electric welding field.
Background technology
Friction stir welding FSW(Friction Stir Welding) is the new friction stir welding technique that was proposed in 1991 by Britain institute of welding TWI (The Welding Institute).Its operation principle is the stirring-head insertion workpiece position to be welded with a kind of special shape, by the agitating friction between stirring-head High Rotation Speed and workpiece, friction produces heat makes this position metal be in the thermoplasticity state, and under the pressure-acting of stirring-head from its front end to the rear portion Plastic Flow, thereby weldment is bonded together.Owing to there is not the fusing of metal in the stir friction welding process, it is a kind of solid-state connection procedure, so there are not the various defectives of melting welding during welding, can weld the nonferrous materials that is difficult to weld with fusion welding method, such as aluminium and high strength alumin ium alloy, copper alloy, titanium alloy and foreign material, composite plate weld etc.
Stir friction welding seam is through plastic deformation and dynamic recrystallization and form, and the weld metal zone grain refinement without the dendrite of melting welding, is organized fine and closely wovenly, and the heat affected area is narrow during than melting welding, the defectives such as alloy-free melting loss of elements, crackle and pore, and combination property is good.Compare with traditional fusion welding method, its nothing is splashed, flue dust, does not need to add welding wire and protective gas, and joint performance is good; Owing to be Solid-phase welding technique, heating-up temperature is low, and the welding heat affected zone microscopic structure changes little, substantially remains unchanged such as metastable phase, and this is highly beneficial for heat treatment reinforcement alloy and precipitation strengthening alloy; The residual stress of postwelding and distortion are very little, and be substantially indeformable for the sheet alloy postwelding.Compare with common friction welding (FW), it can not be subjected to the restriction of axial workpiece, can weld straight weld, angle welding.Traditional welding technique welding aluminum alloy requires effects on surface to remove oxide-film, and in 48 hours, process, and Friction stir welding as long as before weldering wipe oil, and not high to matching requirements, and friction stir welding than melting welding save the energy, pollution is little.
But also there is certain shortcoming in friction stir welding: 1, be lower than melting welding at agitating friction welding speed per hour degree; 2, treat that the weldment clamping requirement is high, treat the weldment requirement in the welding process and add certain pressure that reverse side requires to have backing plate; 3, the postwelding termination forms the hole that stirring-head is residual, generally needs repair welding or mechanically cutting; 4, stirring-head bad adaptability, the different-thickness sheet alloy requires the stirring-head of different structure, and the stirring-head quick abrasion; 5, that is that all right is ripe for technique, is limited at present member simple in structure, such as straight structure, circular configuration; 6, the Friction stir welding parameter is simple, mainly contains the rotary speed of stirring-head, the translational speed of stirring-head, the pressure of butt-welding fitting and the size of stirring-head etc.
