Description
Technical field
The present invention relates to a kind of thin plate edge joint laser welding method synchronous with rolling, and belongs to Materials Processing Engineering neck
Domain.
Background technology
The thin plate type of attachment being commonly used at present in industry is mostly to overlap or dock, mainly in automobile board, motor
The component such as axle and housing, water tank.Usual material is austenite and martensitic stain less steel, precipitation-hardening stainless steel, Langaloy
With titanium etc..But in overlap joint or banjo fixing butt jointing welding process, because the easy buckling deformation of thin plate make it that overlap joint effect is poor,
Issuable stomata and crackle can also reduce its mechanical property during docking.Therefore, in the connection procedure of sealing container, one
As except using overlap joint or docking in addition to, it is also possible to using another joint form --- edge joint.
According to pertinent literature, most-often used method is TIG welderings and micro-plasma arc welding, is also easy to produce electric arc during welding and endures
Spend it is small, there are the wild effects such as double arcs, have that cooling shrinkage stress is big, and heat input is big, speed of welding is low, welding stress and
Deformation is big, easily the shortcomings of generation fire check.
At present, plate sheet welding is carried out using conventional method and following some problems is present：
(1) it is less than below 1.0mm edge joint for thin plate edge joint welding, especially thickness, is welded using arc-welding
Weld metal easily lower time, causes appearance of weld poor, or even can not connect in termination process；
(2) traditional arc welding fusion penetration is shallow, and shearing strength is low；
(3) thermal weld stress is big, and workpiece deformation is larger, and welding process is unstable, easily produces defect, to mechanical property
And sealing has a significant impact；
(4) speed of welding is small, and efficiency is low, is not suitable with and produces in enormous quantities；
(5) Automated condtrol of welding process is difficult to, automaticity is low.
With the development of science and technology, butt joint mechanical property and sealing requirements also increasingly improve, thus its manufacturer
The improve and perfect of method has quite great meaning.Laser as " most there is the welding technique of development potentiality 21st century " it
One, because it has energy density high, weldquality is good, and depth-to-width ratio is big, and heat affected area is small, and welding deformation is small, and welds speed
The advantages that fast and easy to automate is spent, is widely used in the industrial production.
But laser welding requires very high to structural member assembly precision, for thin plate edge joint, how to ensure laser welding
During plate be brought into close contact with the stability of welding process be this Joining Technology key technology.Meanwhile laser welding
Weld seam is narrower, and during actual welding, a large amount of gas hole defects are also easy to produce in joint, and disadvantage mentioned above is unfavorable for such knot
The mechanical property and sealing of component.
The content of the invention
The present invention is directed to that the light leak easily occurred during laser welding thin plate edge joint, appearance of weld be discontinuous, weldering
After deform the problems such as big, and propose the method for laser welding that a kind of thin plate edge joint synchronously rolls.
It is contemplated that welding thin plate edge joint, using the laser welding method synchronous with rolling, carries out individual layer welding
Satisfactory weld seam is obtained, its schematic diagram is as shown in Figure 1.Laser is to be improved conventional laser weldering with rolling synchronous welding
And with rolling the method obtained by processing combines with weldering.A rolling is placed respectively in the two thin plate both sides that parallel gapless is placed vertically
Wheel, rolls to weld seam in welding process, makes the strict centering of weld seam, laser beam is located at two flat board seam crossings, two roller phases
Constant is kept to laser beam position, completes to weld by the rotation of roller and the movement of laser beam.
The method for laser welding that a kind of thin plate edge joint of the present invention synchronously rolls, it is to follow the steps below
's：
Step 1:The both side surface of the position to be welded of workpiece to be welded is polished or cleaned；
Step 2:Workpiece to be welded after polishing or cleaning is fixed on welding tool setup；
Step 3:Holding roller is horizontally disposed in welding direction both sides, and two rollers are highly consistent, and apart from weld seam upper surface
Vertical range is the two flat board seam crossings that 1~10mm, laser beam vertical incidence, and focus are located at workpiece to be welded, two roller phases
Constant is kept to laser beam position, two-wheeled and workpiece contact position to be welded and laser beam horizontal range L be -100mm~
100mm；Welding is realized by the rotation of roller and the movement of laser beam；Wherein, roller diameter is 50~300mm；Roller is thick
Degree≤20mm；Contact face width is 1~10mm；
Step 4:Technological parameter is set, laser power is 500W~5kW, and defocusing amount is ﹣ 3~﹢ 3mm, and protection gas uses Ar
Gas, shield gas flow rate are 5L/min~35L/min；Roller pressure is 1kN~20kN, and speed of welding is 0.5~3m/min；
Step 5:Laser and rolling device power supply are opened, starts laser synchronization and rolls welding control system, implement weldering
Connect；Complete the laser welding that described thin plate edge joint synchronously rolls.
The present invention mainly has some following advantage compared to the welding of traditional lap joint：
1st, compared to conventional arc weldering etc., efficiency is significantly improved, speed of welding, reduces production cost.Reduce heat input,
Residual deformation and residual stress are reduced, reduces defect, material welding hot crack tendency is reduced and eliminates stomata, improve joint mechanics
Performance and sealing；
2nd, compared to single laser welding, by being rolled to weld seam both sides, effect have it is following some：(1) not only dock
Head fixation is stronger, eliminates inter-plate gap, reduces assembly precision requirement, preferably using laser energy, prevents light leak and weld seam
Shaping is discontinuous.(2) while the requirement to preceding working procedure (shear) linearity is reduced, reduces production cost, improve weldering
Connect quality.(3) due to having used roller roll with weldering, can not only reduce the deformation of thin plate, reduce postwelding it is orthopedic into
This, and weld seam internal stress can be reduced, significantly improve the fatigue behaviour of weld seam.
