has anyone had datas about laser weld

[soft8]

has anyone had datas about laser weld,any datas will be appreciated.i need  it for my recent project.

Soft8:

Can you be specific about your requirement?

what kind of data do you need? only welding? robot interfacing? which robot? which machine?

[soft8]

ok,we use some electrical  components of  fronius and scansonic  for laser station.they are used to controll the the laser of arc welding .to my depressing, i can't find any information about the components and also the  working  process of laser. i never use it before. do you have any manual or other materials  about them. thank you,Robotter.

I would be surprised if you find any 'data' for this on the internet.  I've done extensive laser welding in the past, and here is the summary of the process issues you must develop:

1.  Strength of weld is dependent upon depth of penetration and geometry of penetration, and the design engineers specify this minimum requirement.  The method we used to determine this was destructive testing:  cut the part through the weld, polish and etch the section using typical metallography techniques, and view the weld profile under microscope to determine weld puddle dimensions.

2.  Process parameters that you must develop are: 
2.1.  laser beam axis incident angle
2.2.  continuous beam or pulsed beam (and therefore pulse frequency)
2.3  traverse speed along the weld path
2.4  peak laser power
2.5  average laser power
2.6  part clamping requirements (clamped tightly or loosely held)
2.7  fixturing requirements
2.8  laser pulse width (time per pulse)


3.  then you must handle the equipment needs:  beam delivery, focussing optics, spatter protection, beam power quality

thank you,TygerDawg. i have got some material  about laser welding.your reply is good,which inludes  the most parameters we should set. thank you.do you have any material about scansonic ALO.

[TygerDawg]

No, I guess not.  I don't even know what "scansonic ALO" is !
