Laser Welding Aluminium

[donkekeli]

y'all just a bunch of musing crackpots

[tangnatalaga]

Laserbeams can weld amazing stuff. Even the human tissue!!! The heat from laser beams are different because laser are made of coherent electromagnetic wave.

Definitely not resistance welding. For resistance welding you need two opposing electrodes. Otherwise the 1000 lb electrode force required would buckle the structure. I see only one roller. Not resistance welding.

[OldHolborn24]

Well, i am not sure that you are more clever than the constructors of those laser welding robots.

[bozzza69]

its just fusing the two metals by heatin them together which creates a weld prone to cracking but obviously works fine on car bodys

[mattaluminum]

why he wouldn't be more clever than the constructors :) ,how told you that the constructors are just worring about the welding resistance ,

they are more worried about the productivity and the rentability , to use 2 oposite electrode will be more complexe,and the productivity will be less. i guess ..

Oh and that body is not aluminium. the only audis with the alloy space frame technology are the a2, a8 and the new TT. this is an audi a4 wich only has an alloy bonnet and front gaurds. the alloy cars are not laser welded they use a special type ove rivit to hold it all together plus a few tig welds.

I guess you are minimizing the ammount of heat applied to the HAZ with a lazer thus reducing any plate defect. I'm guessing this is CMT?

[narner]

why would the manufacture spend the money on a lazer welder when a lazer guided mig would be more economical?

[Seamart07]

Way more heat input

This is laser guided welding, not laser welding.

The welding is actualy resistance welding with the lasers being used as proximity guides.

[daggermind]

That is laser welding, u can see the light and the rollers to press the metal together. It cannot be anything else. And the process is with low noise and smoke. It is infact LASERED.

[HemiHotRod]

Sorry but it IS resistance welding. The rollers are the conductors. It works on the same principle as spot welding, except you have a continuous joint instead of just spots.

[goonads982]

I Work on audi/vw cars all day long and I can tell ya that it is laser welding. you get much more weld contact with this method giving you a more rigid chassis.

[CruxMeaLux]

i agree with you.

And the robot welder doesn't get yelled at by the boss...but I'd like to see the robot weld on an anodized aluminum radar arch on a boat...will never happen.

[argus91]

Never tired, never sick, never shake or forget something, zero error, the welding joint is always the same, like duplicate, perfect job! One more generation and there will be almost no more welder in a workshop.

[SamRhesus]

Looks like a mig to mee. I would agree that the laser is meerly guiding.

[marek0086]

ye thats right. This guys a dickhead :)

[mrkiky]

Is that the actual laser doing the welding? Cause it kinda gave me the impression that the laser is low powered and is only used to guide the robot arm....

One has to wonder what are the advantages between laser welding and spot welding..

[sabek210]

It think that the robot missed a spot... LOL. haha Nice Video
