Description
Technical field
The invention belongs to welding field, it is related to a kind of welding method suitable for thin plate or ultra thin plate.
Background technology
Agitating friction weldering is a kind of new solid phase joining technique, and its principle is that materials to be welded revolves in the high speed of stirring-head
Turn Plastic Flow, interface under the collective effect of frictional heat and axial compression it is broken formed by a kind of solid diffusivity.Phase
Than in traditional melt welding method, agitating friction weldering has heat input, welding deformation small, the features such as excellent in mechanical performance.It is special
Shi Yongyu not low melting material, the welding of such as Al alloys andMg alloys.
With development in science and technology progress, Aero-Space, automobile, shipbuilding industry are also more next to energy-saving and emission-reduction and light-weighted requirement
Higher, substituting ferrous materials and slab using light material or light sheet material becomes a kind of development trend, therefore the weldering of thin plate
Connection technology has been increasingly becoming the new focus of research of welding field.The traditional fusion welding method post welding distortion of thin plate is big, orthopedic difficulty, and
There is intrinsic weld seam and problem be thinned in agitating friction weldering, it is difficult to realize the welding of thin plate or ultra thin plate.
Thus it is badly in need of finding a kind of interconnection technique suitable for thin plate or ultra thin plate.
The content of the invention
The present invention rubs for the Welding Problems of thin plate and ultra thin plate there is provided a kind of stirring suitable for thin plate and ultra thin plate
Wipe welding method.
It is achieved through the following technical solutions when of the invention.
One kind is applied to thin plate and ultra thin plate friction stir welding method, comprises the following steps：
The first step, will clear up dry by upper and lower surface oxide-film, greasy dirt of the upper surface of welding plate material, interface and cover plate etc.
Only, it will be assembled, be fixedly clamped on composition backing in I type by welding plate material.
Cover plate, by cover plate central alignment by welding plate material joint, is pressed abd fixed on by welding plate material by second step with press strip.
3rd step, chooses the stirring-head progress welding that stirring scalp acupuncture length is slightly less than superposition thickness of slab；
4th step, cover plate is removed identical with both sides mother metal position thickness to position while welding.
Require that cover plate materials are identical with by weldering sheet material in the first step, weld preceding alcohol or acetone by below cover plate
And by welding plate material upper surface wiped clean, cover sheet thickness and added and between 2~5mm by weldering sheet metal thickness, preferably 3mm.
Required in the second step cover plate with it is sturdy by welding plate material, be not allow for the gap more than 0.1mm, stirring-head center
The deviation of line and axis of a weld is not more than 0.3mm.
Suitable agitation head is chosen in 3rd step, welding parameter is determined, stirring-head enters centrally along by welding plate material interface
Row welding.Materials to be welded is plastified by the primary friction heat production of the stirring-head shaft shoulder and cover plate, destruction interface is formed and effectively connected
Connect.Agitating friction is eliminated to be welded in by the thinned problem on welding plate material.The shaft shoulder requirement of stirring-head is less than cover plate width, mixing needle
Length is equal to subtracts 0.1~0.2mm by welding plate material and the cumulative thickness of cover plate.
The cover plate on upper strata is removed by mach mode after the completion of being welded in 4th step.
Thin plate and the friction stir welding method of ultra thin plate that the present invention is provided, compared with prior art, the advantage is that：
First, problem is thinned in the weld seam that thin plate and ultra thin plate agitating friction weldering are solved by increasing cover plate, with sweating heat
Input is small, and post welding distortion is small, the advantages of strength of joint is high.
2nd, the friction stir welding method of thin plate and ultra thin plate proposed by the present invention possesses simple to operate, strong adaptability etc.
Feature.
The present invention can effectively solve the agitating friction welding problem of thin plate and ultra thin plate.
