La tubería soldada por arco sumergido en espiral (SSAW) es una tubería de acero en tiras con un ángulo de formación (ajustable) entre la dirección de avance y la línea central de la tubería formada. Se suelda mientras se forma y la soldadura se convierte en espiral. La ventaja es que se pueden producir flejes de acero con las mismas especificaciones. Los tubos de acero de varios diámetros tienen una gama más amplia de materias primas y las soldaduras pueden evitar la tensión principal y tener mejores condiciones de tensión. La desventaja es que el tamaño geométrico es pobre, la longitud de la soldadura es más larga que la de los tubos con costura recta y las grietas, poros y defectos de soldadura, como inclusiones de escoria y desviaciones de soldadura, hacen que la tensión de soldadura esté en un estado de tensión de tracción.Después Para mejorar este proceso en el extranjero, la materia prima se cambia a la placa de acero, de modo que se separan el conformado y la soldadura. Después de la soldadura previa y el endurecimiento, y la expansión en frío después de la soldadura, la calidad de la soldadura es cercana a la de las tuberías UOE.
