Abstract

Método y cabezal para unión de piezas de tubos de acero inoxidable; que se sueldan empleando el sistema (TIG) en atmósfera inerte para evitar la nitruración del material, efectuándose la soldadura con un equipo especial que dispone de un cabezal orbital, consistiendo dicho método en realizar, primeramente una expansión en el extremo de las piezas a unir (2) y (3) con un diámetro interior igual al diámetro exterior del tubo original, introduciendo en dichas expansiones los extremos rectos del codo (1), para efectuar a continuación la soldadura.
