The atomic hydrogen torch is also known as oxy- hydrogen torch. These atoms are produced through dihydrogen dissociation with the help of an electric arc which results in huge amount of energy.
Energy released = 435.88 kJ mol-1
This energy is used in generation of 4000 K temperature which is used in cutting and welding of metals.
Therefore, atomic hydrogen torches are used for this purpose i.e., it allows to recombine on the particular surface to be welded for the generation of particular temperature.Answered by Pragya Singh | 1 year ago
