Dhererka Qulqulka-Arc alxanka(LSAW) Beebku waxa ay qabataa tignoolajiyada alxanka fallaadho ee quusta, iyada oo adeegsanaysa alxanka buuxinta, qulqulka ilaalinta walxaha arc aasan.
LSAW waa soo gaabinta Ingiriisida ee dhuumo bir ah oo tol ah oo toosan.Habka wax soo saarka ee tuubada birta tolsan ee toosan ee arc waxaa ka mid ah tignoolajiyada samaynta JCOE, gariiradda samaynta tignoolajiyada alxanka quuska iyo farsamada samaynta UOE.
Habka soo saarida Dhuumaha Dhererka Submerged-Arc Welded(LSAW) waa sida soo socota:
Baadhitaanka saxanka Ultrasonic → shiidista cidhifka → hore u laabashada → samaynta → alxanka ka hor → alxanka gudaha → alxanka dibadda → Kormeerka Ultrasonic → Kormeerka raajada → Kordhinta → tijaabada hydraulic →l.Chamfering → Kormeerka Ultrasonic → Baaritaanka raajada → Baaritaanka walxaha magnetic ee dhamaadka tuubada

Baaritaanka Hydrostatic
Tijaabada NDT(RT)
Tijaabada NDT(UT)
Tijaabada laabta-Dherer ku filan oo tuubo ah waa in ay istaagtaa iyadoo qabow ilaa 90° oo ku wareegsan meeraha cylindrical.
Tijaabada fidsan-inkasta oo aan tijaabada loo baahnayn, tuubooyinku waa inay awoodaan inay buuxiyaan shuruudaha tijaabada.
Baaritaanka Hydro-static-marka laga reebo sida loo ogol yahay, dherer kasta oo tuubo ah waa in lagu sameeyaa tijaabada hydrostatic iyada oo aan la daadin darbiga tuubada.
Tijaabada koronto ee aan burbursanayn-Beddelka tijaabada hydro-static , jirka buuxa ee tuub kasta waa in lagu tijaabiyaa tijaabo koronto oo aan burbursanayn .Halka lagu sameeyo tijaabada koronto ee aan burbursanayn, dhererka waa in lagu calaamadiyaa xarfaha"NDE"
Baaritaanka ultrasonic
