Abstract

Procedimiento y cámara submarina para realizar trabajos en una atmósfera de gas sobre elementos en forma alargada tal como trabajos de soldadura, procedimiento caracterizado porque comprende las siguientes operaciones: se rodea la zona sobre la que debe efectuarse la soldadura, por la cámara flexible replegada del lado de los mencionados elementos y se realiza la estanquidad a nivel del cuello de ésta alrededor de al menos uno de los elementos; se engancha a la parte inferior de la cámara los cables de retención para evitar el efecto de boya debido a la insuflación del gas; y se insufla en la cámara una mezcla de gas y se expulsa el agua hasta que la cámara se despliegue y adopte la forma de una bolsa abierta en su parte inferior.
