Abstract

L'invention concerne le soudage sous l'eau. Elle se rapporte à un procédé selon lequel un soudeur plongeur porte un masque respiratoire 10 qui reçoit des gaz respiratoires d'une cloche 22 de plongée et dont les gaz expirés sont renvoyés dans la cloche 22 si bien que les gaz respiratoires et les gaz expirés ne contaminent pas l'atmosphère de la chambre 2 dans laquelle est réalisée l'opération de soudage. Application au raccordement des tuyauteries sous l'eau.
