O paipa u'amea LSAW (Longitudinal Submerged Arc Welding) o se ituaiga paipa u'amea ua fa'apipi'iina e iloga i la latou faiga gaosiga tulaga ese ma le tele o fa'aoga. O nei paipa e gaosia e ala i le fausiaina o se u'amea i se foliga lapotopoto ma fa'apipi'i fa'asolosolo i le fa'aaogaina o metotia fa'apipi'i arc i lalo o le vai. O se aotelega lea o paipa u'amea LSAW:

Faiga o le Gaosiga:
● Sauniuniga o Ipu: O ipu u'amea e maualuga le tulaga lelei e filifilia e fa'atatau i mana'oga fa'apitoa, ma fa'amautinoa ai meatotino fa'ainisinia ma le fa'asologa fa'akemikolo e mana'omia.
● Fausiaina: O le u'amea ua mamanuina e pei o se paipa lapotopoto e ala i ni faiga e pei o le punou, ta'avale, po'o le oomiina (JCOE ma le UOE). O pito ua uma ona fa'api'o e fa'afaigofie ai le fa'avevela.
● Fa'avevela: E fa'aaogaina le fa'avevela o le arc i lalo o le vai (SAW), lea e tausia ai se arc i lalo o se vaega o le flux. O lenei mea e maua ai ni fa'avevela e sili ona lelei ma ni fa'aletonu laiti ma se fusion sili ona lelei.
● Su'esu'ega Ultrasonic: A mae'a le uelo, e faia le su'ega ultrasonic e iloa ai so'o se fa'aletonu i totonu po'o fafo i le vaega uelo.
● Fa'alauteleina: E mafai ona fa'alauteleina le paipa e ausia ai le lautele ma le mafiafia o le puipui e mana'omia, ma fa'aleleia atili ai le sa'o o le fua.
● Su'esu'ega Fa'ai'u: O su'ega atoatoa, e aofia ai le su'esu'ega va'aia, siaki o fua, ma su'ega o meatotino fa'ainisinia, e fa'amautinoa ai le lelei o le paipa.

Fa'amanuiaga:
● Taugofie: O paipa LSAW e ofoina atu se fofo taugofie mo paipa tetele ma faʻaoga fausaga ona o le lelei o le faiga o gaosiga.
● Malosi Maualuga: O le metotia o le fa'apipi'iina o paipa i le umi e maua ai ni uiga fa'amekanika malolosi ma tutusa.
● Sa'o le Fua: E sa'o lelei fua o paipa LSAW, ma talafeagai ai mo galuega e iai le fa'atagaina faigata.
● Tulaga Lelei o le Fa'avelaina: O le fa'avelaina i lalo o le vai e maua ai ni fa'avelaina e sili ona lelei ma e sili ona lelei le fa'afefiloi ma e itiiti ni fa'aletonu.
● Fetuuna'i: E fa'aaogaina paipa LSAW i le tele o pisinisi, e aofia ai le suau'u ma le kesi, faufale, ma le sapalai o le vai, ona o lo latou fetuutuunai ma le umi.

I se aotelega, o paipa uʻamea LSAW e gaosia e faʻaaoga ai se faiga saʻo ma lelei, e mafua ai ona maua ni paipa e tele ona faʻaaogaina, taugofie, ma malolosi e talafeagai mo le tele o faʻaoga faʻapisinisi.
