Enye yezinto ezibalulekileyo ekufuneka ziqwalaselwe xa kudityaniswa ii-arc imibhobho yegesi yendalo luhlobo lwendlela yokudityaniswa esetyenziswayo.ityhubhu edibeneyo ejikelezayos, eyona ndlela isetyenziswa kakhulu yiteknoloji ye-inferined arc welding (SAW). Oku kubandakanya ukusebenzisa i-granular flux, egalelwa phezu kwendawo ye-welding ukudala umoya okhuselayo othintela i-oxidation kunye nezinye izinto ezingcolisayo ukuba zingachaphazeli i-weld. Oku kubangela i-weld esemgangathweni ophezulu, efanayo eneziphene ezincinci.

Enye into ebalulekileyo ekufuneka iqwalaselwe xa kudityaniswa i-arc kwimibhobho yegesi yendalo kukukhethwa kwezinto zokugcwalisa i-weld. Izinto zokugcwalisa zisetyenziselwa ukugcwalisa naziphi na izikhewu okanye ukungalungelelani kwi-weld, nto leyo edala ikhonkco eliqinileyo nelihambelanayo. Kwimibhobho edibeneyo ejikelezayo, kufuneka kusetyenziswe izinto zokugcwalisa ezihambelana nomgangatho othile wentsimbi esetyenzisiweyo kunye neemeko zokusingqongileyo apho umbhobho ujongene khona. Oku kuqinisekisa ukuba i-weld inokumelana noxinzelelo kunye namaqondo obushushu afunyanwa yimibhobho yegesi yendalo.

Ukongeza kwiinkalo zobugcisa bokuwelda nge-arc, kubalulekile ukuqwalasela iziqinisekiso namava omenzi we-arc owenza umsebenzi. Ukuwelda nge-arc kwimibhobho yegesi yendalo kufuna inqanaba eliphezulu lesakhono kunye nobuchule, kunye nokuqonda ngokupheleleyo imingeni kunye neemfuno zomsebenzi ezizodwa. Kubalulekile ukusebenza nabamenda abanamava nabaqinisekisiweyo abanokuvelisa rhoqo ii-welds ezikumgangatho ophezulu ezihlangabezana nemigangatho eqinileyo yoshishino.

Ukuqukumbela, umbhobho wegesi yendalo odibeneyo we-spiral welded tube arc welded yinxalenye ebalulekileyo kushishino lwemibhobho. Ifuna ukuqwalaselwa ngononophelo kweendlela zokuwelda, izixhobo zokuzalisa, kunye neziqinisekiso zomshiseli owenza umsebenzi. Ngokuqinisekisa ukuba ezi zinto zifumana ingqalelo eziyifaneleyo, kuya kuba nokwenzeka ukwenza imibhobho yegesi yendalo ehlangabezana neemfuno zoshishino zokhuseleko, ukuthembeka kunye nokusebenza ixesha elide.
