Abstract
The present invention relates to a kind of angle joint method for laser welding, include the following steps, step 1: taking two welded plates and the side of two welded plates is allowed to be spliced to form angle joint to be welded；Step 2: the two sides for being focused on two welded plates respectively using double laser beam are welded, and obtain angle joint weldment.Preferably, the position for applying laser in the step 2 is distributed about the two sides of the stitching portion of two splice plates.By using above-mentioned technical proposal, double laser beam is distributed in the two sides of the stitching portion of two splice plates, during the welding process, stitching portion can be made to obtain round and smooth as a result, rather than sharp state.
Description
Technical field
The present invention relates to welding technology fields, and in particular to a kind of angle joint method for laser welding.
Background technique
The current more universal connector method for laser welding that cries is: after two welded plates are spliced, in the single beam in stitching portion
Laser welding allows two welded plates to realize the purpose of connection, and to will lead to welding outer surface not smooth enough for this welding manner, and
And difficulty in weld seam pair is larger is difficult to achieve the purpose that smooth, therefore has much room for improvement.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of angle joint method for laser welding,
With welding point smooth outer surface is made, defect insensitive to weld seam centering in welding process is avoided, and improve weldering
The advantages of connecing quality.
To achieve the above object, the present invention provides the following technical scheme that a kind of angle joint method for laser welding, including such as
Lower step,
Step 1: taking two welded plates and the side of two welded plates is allowed to be spliced to form angle joint to be welded；
Step 2: the two sides for being focused on two welded plates respectively using double laser beam are welded, and obtain angle joint weldment.
Preferably, the position for applying laser in the step 2 is distributed about the two sides of the stitching portion of two splice plates.
By using above-mentioned technical proposal, double laser beam is distributed in the two sides of the stitching portion of two splice plates, in welding
In the process, stitching portion can be made to obtain round and smooth as a result, rather than sharp state.
In conclusion the invention has the following advantages:
The present invention overcomes the problems, such as current angle joint laser welding, and the angle joint that laser welding can be allowed to complete obtains round and smooth and flat
It is whole as a result, it is possible to adapt to the demand of the industrial application of current angle joint.

Specific embodiment
A kind of angle joint method for laser welding includes the following steps as shown in figs 1 to 6,
Step 1: taking two welded plates and the side of two welded plates is allowed to be spliced to form angle joint to be welded；
Step 2: the two sides for being focused on two welded plates respectively using double laser beam are welded, and obtain angle joint weldment.
The position for applying laser in the step 2 is distributed about the two sides of the stitching portion of two splice plates.
The distance between twice laser beam relationship can be adjusted mutually, i.e., twice laser beam can be simultaneously to same direction
Mobile or twice laser beam is mobile towards direction that is close to each other or being located remotely from each other, to adapt to different operating conditions.And other techniques
Parameter, such as the intensity of laser meet production requirement.
The present invention is using self-melting and welding method, and by double focus laser welding manner, i.e. twice laser beam is in two
The stitching portion of the two sides of the stitching portion of a splice plate, two splice plates will be heated and weld together in turn from molten, to reach
The round and smooth and smooth result to outer surface.
In addition double focus laser welding manner, can be according to different operating conditions, by the way of the switching of single bifocus, engineering
Using more flexible.The requirement to weld seam cooperation precision is reduced, the requirement of laser welded seam accuracy of alignment is reduced.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to restrict the invention, all in design structure of the invention
Within think of, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
