WebDec 20, 2001 · 3.1. Fundamentals and history. Oxygen and hydrogen in a flame used for welding, brazing or cutting combine into water vapour as defined by the following equation: (1) H 2 +0.5 O 2 = H 2 O + energy emitted The process efficiency is around 60%. From the above explanation, it is obvious that hydrogen is used here as fuel. WebThis process of welding can be done manually or automatically. Atomic hydrogen or Tungsten arc welding is a fusion process in which an arc is created between two Tungsten (non-consumable) electrodes. A stream of hydrogen is passed through an electric arc between two Tungsten electrodes. A.C. is used at the time of welding.
