Hydrogen Plasma Welding

[Stuggi]

Anyone heard of this? I remember seeing a patent from the beginning of the 20th century, but I've never heard of them...

Basicly it consist of a torch that passes hydrogen through a arc...

Also called "atomic hydrogen welding"... Seems the temperature in the arc is hotter than oxy-acetylene, way hotter...

There are two tungsten electrodes and hydrogen is passed over them as both a shield and fuel. It gets that hot you can weld tungsten with it...

Here's a video:

Right click, click "zoom in" and drag it so you can see it, doesn't look that good but you can get the jist...

Try googling it, not used that much these days, like arc welding aluminium, due to lack of need...
