Abstract

Método y cabezal para unión de piezas de tubos de acero, 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 los extremos (11) y (21) de las piezas a unir (1) y (2), con un diámetro interior igual al diámetro exterior al tubo original, y colocar un casquillo de tubo (3), introducido en el interior, de longitud igual a las dos zonas expansionadas, efectuándose a continuación la soldadura, una vez que se han acoplado las piezas enfrentadas con el casquillo (3) y en su interior, el cual garantiza el alineamiento a la vez que se sirve de base fundente para la soldadura orbital efectuada alrededor de la unión.
