Abstract

L'invention concerne un procédé de soudage à l'arc dans une chambre à une pression supérieure à la pression atmosphérique normale. Elle se rapporte à un procédé de soudage à une pression dépassant 3 bars, à l'aide d'une électrode de soudage à l'arc à âme de flux contenant un agent désoxydant fort, le soudage étant réalisé avec un courant annulaire de gaz protecteur contenant au moins un gaz inerte tel que l'argon et 1 à 6 % en volume d'oxygène Application au soudage à l'arc sous l'eau.The invention relates to a method of arc welding in a chamber at a pressure greater than normal atmospheric pressure. It relates to a welding process at a pressure exceeding 3 bar, using a flux core arc welding electrode containing a strong deoxidizing agent, the welding being carried out with an annular current of protective gas containing at least one inert gas such as argon and 1 to 6% by volume of oxygen Application to underwater arc welding.
