Uxinzelelo lwentsalela loMbhobho we-LSAW lubangelwa ikakhulu ukupholisa okungalinganiyo. Uxinzelelo lwentsalela ngugqirha wenqanaba lokuzilawula ngaphakathi ngaphandle koxinzelelo ngaphandle kwamandla angaphandle. Olu xinzelelo luhlumelo lukhona kumacandelo ashushu achumileyo amacandelo ahlukeneyo. Inqanaba elikhulu ubungakanani becandelo ngokubanzi secandelo, kokukhona xinzelelo lube lulo.
Nangona uxinzelelo olushiyekileyo luzingca, lusenempembelelo ethile ekusebenzeni kwamalungu entsimbi phantsi kwamandla angaphandle. Umzekelo, inokuba inefuthe elibi kwingxaki, uzinzo kunye nokungakhathali. Emva kokuba i-welding, i-intermatics engafakwanga kwi-lesall yombhobho ye-LSAW icinezelwe ngamashiti amancinci, okukhokelela kwilelikiweyo. Emva koko isilisa siyiphosa kakhulu intsebenzo ye-ntenle yomphunga we-LSAW ecaleni kobunzima, kwaye i-interlather inokwenzeka xa i-weld incipha. I-Suren yengingqi ibanjwe yi-Weld Shrinkage ihlala izihlandlo ezininzi zesivuno sendawo, ebaluleke kakhulu kunokuba ibangelwa ngumthwalo. Ukongeza, umbhobho we-LSAW uya kuba ne-T-Wids ezininzi, ke amandla okufumana iziphene ze-welding kuphuculwe kakhulu. Ngapha koko, uxinzelelo lwentsalela le-well kwi-T-id inkulu, kwaye intsimbi ye-Wold ihlala kwimo yoxinzelelo olufutshane, olonyusa amathuba okuba.
Umthungo we-welding we-Pimural Arc of Peped Pedle Deped ihanjiswa kumgca weSpiral, kwaye ii-wels zide. Ingakumbi xa i-welding phantsi kweemeko ezinamandla, i-weld ishiya indawo yokwakha ngaphambi kokupholisa, ekulula ukuvelisa imifuno eshushu ye-welding. Isikhokelo sobuqhetseba sihambelana ne-WALD kwaye senza i-Angle equkene ne-axis yentsimbi, ethetha ngokubanzi, i-engile iphakathi kwe-30-70 °. Le Angle ihambelana nje ne-engile yokuwiswa, ke ukugoba, ukugoba, ukugcoba, i-tedsterive, i-anti-tracresteries ayilunganga njengobhobho yesayizi. Kwangelo xesha, ngenxa yokusikelwa komda wendawo ye-welding, i-sardle kunye ne-Shidge Fillge Welge ye-Welding ichaphazela imbonakalo. Ke ngoko, i-NDT yemipu ye-SSAW imele yomelezwe ukuze kuqinisekiswe umgangatho we-welding, kungenjalo umbhobho we-SSAW akufuneki usetyenziswe kwizihlandlo ezibalulekileyo zentsimbi.
