Laser welding can improve the production efficiency of the laser welding process compared with the traditional welding technology, laser welding technology to make the links between different steel to achieve the combination of molecular level;
After welding, different steel plate is equivalent to a single piece of steel plate.
This technology has many advantages, such as welding equipment and welding with no mechanical contact, reduce pollution of the artifacts;
Concentrated heating, energy density;
Small heat affected zone, the thermal deformation and thermal damage less;
Beautiful, weld strength;
Through the numerical control, can precisely control the output energy, welding speed, higher productivity.
Roof is divided into laser welding and spot welding welding two kinds, one is the use of laser thermal effect, one is the use of current heating, heating the material to melt, then unifies in together, the flat welding, laser welding is better than spot welding, but cannot be laser overlap welding, because behind the light cannot penetrate into the material, and using overlap welding, spot welding can be through the metal, so the combination of spot welding can make a bigger surface.
And overlapping is to increase the thickness of the original material twice, is equivalent to in welding at the same time, in combination with parts produced the effect of a strengthening rib, achieved a higher strength, laser welding, the main role, is to save the cost!
There are, of course, a requirement to spot welding, and that is solder to dense, overlapping, in short, with no overlap of the linear combination of welding, laser is preferred.
Many people see the public's roof, bare follow side connected around, surrounded on both sides of the girder in side, there is no other brands that have two black rubber, and that is the laser welding of advantages, that is the roof laser welding can make the vehicle is very beautiful, no two waterproof modesty, black rubber.
Some old vw Volkswagen automobile 4 s shop's propaganda of laser welding, it become the selling point of the public for a period of time, but the high welding strength of laser welding without welding, under the roof of the car, that is, MIG (B column above will go
Argon gas shielded arc welding)
Welding, in order to prevent the laser welding structure strength is not high and there is a problem.
For companies into a new production process, want to consider investment income ratio;
After laser welding on top, which can eliminate edge, so each car can cut down the cost of some.
And laser welding can improve the efficiency of production, because we all know that the public's car in the domestic selling special fire, like the lavida this model is a short supply of the public's current capacity is very high, some models are to be in short supply in the market, so the roof using laser welding is sure to increase production, despite the high cost of laser welding, but the yield and the cost benefit compared to speed up the production to earn much more money will be;
And other car companies, because they have capacity but no sales, so can't into expensive laser welding machine.
Japanese automakers sales is good also, why not use laser welding technology?
Because Japanese cars are more conservative, generally with new technology, Germany is more advanced, dare to be first.
