How does the atomic hydrogen or oxy-hydrogen torch function for cutting and welding purposes? Explain.

Open in App

Solution

Atomic hydrogen atoms produced by dissociation of hydrogen with the help of an electric arc, are followed to recombine on the surface to be welded. Here, tremendous amount of heat is liberated, which is used to generate a temperature of 4000K for cutting and welding purpose.
