What it is
Arc welding process between two tungsten electrodes in a hydrogen atmosphere, using the heat released when the arc-dissociated hydrogen atoms recombine, reaching temperatures above 3,400 °C.
What it led to
- Welding of stainless steel and special alloys
- Later development of TIG welding
- High-temperature industrial applications
- Advances in the study of molecular hydrogen dissociation
