Abstract
The utility model relates to a kind of stainless steel laser stitch welding device, and it comprises upper plate to be welded, lower plate to be welded, cooling gasket, fixture and laser welding system; Lower plate to be welded is placed with at the upper surface of cooling gasket, upper plate to be welded is placed with at the upper surface of lower plate to be welded, upper plate to be welded and lower plate to be welded are that face contacts, and upper plate to be welded, lower plate to be welded and cooling gasket clamp by described fixture, above upper plate to be welded, be provided with laser welding system.The utility model by adding cooling gasket at back of weld, and adopts fixture upper plate to be welded, lower plate to be welded to be welded after compressing with cooling gasket, can obtain back of weld without obvious weld mark and the stitch welding weld seam that meets the demands of Weld Performance.
Description
Technical field
The utility model relates to a kind of laser soldering device, and the utility model especially relates to a kind of stainless steel laser stitch welding device.
Background technology
In prior art, stainless steel stitch welding adopts electric resistance welding to weld mostly, and it is easy to leave welding impression at weld, has a strong impact on finished appearance, can not meet the product that some are higher to appearance requirement.Laser weld due to its heat input little, welding deformation is little, has very large advantage at welding field.But adopt traditional laser welding process to carry out stainless steel stitch welding and still can leave weld mark clearly at stainless steel surfaces.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of and significantly can reduce the weld mark of back of weld stainless steel surfaces, the stainless steel laser stitch welding device of raising welding quality.
According to the technical scheme that the utility model provides, described stainless steel laser stitch welding device, it comprises upper plate to be welded, lower plate to be welded, cooling gasket, fixture and laser welding system; Lower plate to be welded is placed with at the upper surface of cooling gasket, upper plate to be welded is placed with at the upper surface of lower plate to be welded, upper plate to be welded and lower plate to be welded are that face contacts, and upper plate to be welded, lower plate to be welded and cooling gasket clamp by described fixture, above upper plate to be welded, be provided with laser welding system.
The thickness of described upper plate to be welded is less than the thickness of lower plate to be welded.
The thickness of described upper plate to be welded is 0.6 ~ 1.0mm.
The thickness of described lower plate to be welded is 1.5 ~ 2.5mm.
The utility model by adding cooling gasket at back of weld, and adopts fixture upper plate to be welded, lower plate to be welded to be welded after compressing with cooling gasket, can obtain back of weld without obvious weld mark and the stitch welding weld seam that meets the demands of Weld Performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
This stainless steel laser stitch welding device, it comprises upper plate 1 to be welded, lower plate to be welded 2, cooling gasket 3, fixture 4 and laser welding system 5; Lower plate 2 to be welded is placed with at the upper surface of cooling gasket 3, upper plate 1 to be welded is placed with at the upper surface of lower plate 2 to be welded, upper plate 1 to be welded contacts in face with lower plate 2 to be welded, upper plate 1 to be welded, lower plate to be welded 2 clamp with cooling gasket 3 by described fixture 4, above upper plate 1 to be welded, be provided with laser welding system 5.
The thickness of described upper plate to be welded 1 is less than the thickness of lower plate 2 to be welded.
The thickness of described upper plate to be welded 1 is 0.6 ~ 1.0mm.
The thickness of described lower plate to be welded 2 is 1.5 ~ 2.5mm.
During work, first clear up upper plate 1 to be welded and lower plate 2 interface to be welded, clean interface with alcohol, overlay on cooling gasket 3, compress with fixture 4.
The welding condition of adjustment laser welding system 5: power is 1400W, defocusing amount is 0, speed of welding is 3000mm/min, shield gas flow rate is 15L/min.
When defocusing amount is 0, laser facula is minimum, just can realize larger fusion penetration under comparatively low_input_power.In addition because the effect of cooling gasket 3 and fixture 4 makes welding deformation reduce further.Just back of weld can be made almost there is no weld mark by this device.
