LSAW (Longitudinal Submerged Arc Welding) paipa uʻamea o se ituaiga o paipa uʻamea uʻamea faʻaalia e ala i la latou gaosiga tulaga ese ma le tele o faʻaoga.O nei paipa e gaosia e ala i le faia o se ipu u'amea i se foliga fa'ata'ali'i ma fa'au'u uelo fa'aaoga auala uelo fa'afefete.O se fa'amatalaga lautele lea o paipa u'amea LSAW:

Fa'agasologa o le gaosiga:
● Sauniuniga Plate: O paʻu uʻamea maualuga e filifilia e faʻatatau i manaʻoga faʻapitoa, faʻamautinoa le manaʻomia o mea faʻainisinia ma vailaʻau.
● Fausia: O le ipu uʻamea e faʻapipiʻiina i totonu o se paipa cylindrical e ala i gaioiga e pei o le punou, taʻavale, poʻo le oomiina (JCOE ma UOE).O pito e muai pi'o e faafaigofie ai le uelo.
● Uila: O lo'o fa'aaogaina le uelo fa'afu (SAW), lea e fa'atumauina ai le arc i lalo o se fa'afefe.O lenei mea e maua mai ai le maualuga o le uelo fa'atasi ma ni faaletonu laiti ma le fa'afefiloi lelei.
● Suʻesuʻega Ultrasonic: A maeʻa le faʻapipiʻiina, e faia suʻega ultrasonic e iloa ai soʻo se faaletonu i totonu poʻo fafo i le sone faʻafefe.
● Faʻalauteleina: E mafai ona faʻalauteleina le paipa e ausia ai le lautele manaʻomia ma le mafiafia puipui, faʻaleleia le saʻo saʻo.
● Su'esu'ega Fa'ai'u: Su'esu'ega mae'ae'a, e aofia ai su'esu'ega va'aia, su'esu'ega o fua, ma su'ega o mea tau masini, e mautinoa ai le lelei o le paipa.

Tulaga lelei:
● Tau-Tauleleia: O paipa LSAW e ofoina atu se fofo taugofie mo paipa tetele-diameter ma faʻaoga faʻavae ona o le latou gaosiga lelei.
● Malosi Maualuga: O le auala uʻamea umi e maua ai paipa ma mea faʻainisinia malosi ma tutusa.
● Fua Fa'atatau: O paipa LSAW o lo'o fa'aalia ni fua sa'o, e fa'atatau mo fa'aoga ma le fa'apalepale malosi.
● Weld Quality: O le uelo o le arc i lalo e maua ai le maualuga o le lelei o le fusuaga ma le itiiti o faaletonu.
● Faigofie: LSAW paipa e faʻaaogaina i pisinisi eseese, e aofia ai le suauʻu ma le kesi, faufale, ma le suavai, ona o lo latou fetuutuunai ma le tumau.

I le aotelega, o paipa uʻamea LSAW o loʻo gaosia e faʻaaoga ai se faʻagasologa saʻo ma lelei, e maua ai le tele, taugofie, ma le umi o paipa e talafeagai mo le tele o faʻaoga pisinisi.
