  • Use of hydrogen in welding engineering in former times and today
    Suban, Marjan ; Tušek, Janez, 1952- ; Uran, Miro
    The paper treats the history of the use of hydrogen as a combustible or shielding gas in welding. Owing to certain characteristics of hydrogen its use has been reduced through years. Further ... devlopment of welding techology, however, has dictated an increase in the use of hydrogen, particularly due to economic reasons. Hydrogen was used in gas welding, cutting and brazing as early at the beginning of this century. It was a basic combustible gas used in flame processes before the introduction of acetylene. With the introduction of acetylene, hydrogen as a combustible gas fell into oblivion. Engineering development, however, has permitted winning hydrogen and oxygen by electrolysis. Several devices for gas welding, cutting and brazing with hydrogen have made their appearance in the market. The paper deals primarily with advantages of the use of hydrogen in gas process. A decisive part in arc welding process is played by the type of shielding gas used. It affects arc shape, material transfer, energy distribution, temperature distribution etc. In the past an arc welding process called Arc-Atom was known. It used pure hydrogen. Hydrogen in various mixtures however, is used today mainly in TIG welding of high-alloy steels, plasma welding and cutting and in gas mixtures for weld-root protection. The paper also deals with a study on the use of an argon mixture containing a larger portion of hydrogen in TIG and MIG welding process.
