How Do You Use Hydrogen In Welding?
Atomic hydrogen welding also is known as arc-atom welding and Langmuir welding. This type of arc welding produces an arc between a pair of tungsten electrodes in a hydrogen atmosphere. An atomic hydrogen welding torch produces a flame up to 4,000 degrees C and can weld tungsten. Maintain the arc independently of the work you are performing. The metal being welded is a part of the circuit only to the extent that it comes into contact with a portion of the arc. Use hydrogen as a shielding gas. It protects the weld from contamination by other elements such as carbon, oxygen and nitrogen. The hydrogen also serves as a mechanism to transport energy from the arc plasma to the metal you are welding. Perform atomic hydrogen welding without a flux. Unlike other forms of welding, atomic hydrogen welding does not require a flux because hydrogen is such a strong reducer. It can therefore melt alloys without causing surface oxidation. Control the heat by changing the distance between the arc stream
