    It will be a while until people have them in the shed, My partners father enquired about purchasing one for the company he works for in Canada, they are only suitable for thin stock, price was $15,000.00CAD

    Not new tech by any stretch. Might be somewhat novel in that form factor though.
    I'll still go my TIG over that if that's the price point.

    Does this process use any type of filler, or just fuse the base/parent metals at the contact points?

    I suppose if you were needing to add filler, than you'd need to also add flux/shielding of some sort - and then you're pretty much back at TIG anyway?

    My BILs business that makes solar heater SS heat exchangers has been using laser welder for some time.

    Apart from cost there are serious Health and Safety issues for any DIY implementation.

    I still remember a young bloke at work who copped a tiny reflection from a laser - he said he heard a POP and then felt excruciating pain in both eyes. Spent 4 weeks in hospital. His vision sort of returned but everything he sees now has a large inverted "blurry L" in front of it.

    The nozzle has to be in contact with the work piece for the laser to turn on. No one could defeat that! I wonder what the beam focus is like?

    That aside could the welds in the video be much good?(with the possible exception of the external corner weld)
    The laser heats the surface(?) so the weld pool couldn't be deeper than is it wide. right?
    So great if you want to make a bucket, just don't drop it.

    Sure but surface might not be even or on an edge and all it needs is tiny pinhole reflection . . . . . . . . .

    Oh yeah it scares the crap out of me. I was just wondering if the beam could be focused so that say at 10mm it was a 1mm circle but at 150mm it was a 150mm circle(ok that might be a bit much but you get the idea). Thats about a 17000th, even at that with a 1kW laser its still 58mw
