Laser welding

The internet is full of "nearly" good welds. This is very neat, and certainly fit for purpose (looks like it could be some generic framework), but the fact that its all lovely shiny colours means its oxidised. This is not to be celebrated, and means the shielding gas employed was improperly set up, meaning that the metal was still very hot when the inert gas shield was removed/had passed on. To do this (nearly) perfectly you need either a trailing purge or an inert chamber. Nether of which will be practical in most real production environments. This isn't good enough practise to pass aerospace or defence coded work, and is an example of bad process control but high operator dexterity (its very neat). The bead is quite course, I suspect that the welder is going pretty fast, meaning that the gas lens is long gone before the metal has cooled properly. You need both to get a great weld. If some shiny bits race-car shop shows you loads of lovely pretty rainbow coloured welds, walk on by. (I have a very old bit of paper somewhere with CAA BCAR A-8 10 written on it which means once upon a time I could have done that.)

Welding with precision

Id love to see the penetration in X-ray.

My eyes don't miss welding.

Laser welding

Any videos where they Test the join with a hammer? 🤨

Great to go!

That's clearly not laser welding. You can't weld with a laser by hand, the wattages needed are far too high to be safe.

I love those welders but having learned it as a trade I have to say that point and click weld feels like cheating and definitely leaves something to be desired in the way it looks. I still want one though lol

Thats a laser pointer on a regular welder
