Enye yezona zinto zibalulekileyo ekufuneka ziqwalaselwe xa i-arc iwelding imibhobho yegesi yendalo luhlobo lobuchule bokuwelda obusetyenziswayo.Kubaityhubhu edityanisiweyos, eyona ndlela isetyenziswa ngokuqhelekileyo i-arc welding (SAW) iteknoloji.Oku kubandakanya ukusebenzisa i-granular flux, egalelwe phezu kwendawo ye-welding ukudala umoya okhuselayo okhusela i-oxidation kunye nezinye izinto ezingcolileyo ekuchaphazela i-weld.Oku kubangela umgangatho ophezulu, i-weld efanayo kunye neziphene ezincinci.

Olunye uqwalaselo olubalulekileyo xa i-arc idibanisa imibhobho yegesi yendalo kukukhethwa kwezinto zokuzalisa i-weld.Izinto zokuzalisa zisetyenziselwa ukuzalisa naziphi na izikhewu okanye izitenxo kwi-weld, ukudala ibhondi eqinile kwaye ehambelanayo.Kwimibhobho ye-spiral welded, kufuneka kusetyenziswe izinto zokuzalisa ezihambelana nenqanaba elithile lentsimbi elisetyenzisiweyo kunye neemeko zokusingqongileyo apho umbhobho ubonakaliswe khona.Oku kuqinisekisa ukuba i-weld inokumelana noxinzelelo kunye namaqondo obushushu afunyanwa yimibhobho yegesi yendalo.

Ukongeza kwimiba yobugcisa be-arc welding, kubalulekile ukuqwalasela iziqinisekiso kunye namava e-welder owenza umsebenzi.I-arc welding yemibhobho yegesi yendalo idinga umgangatho ophezulu wezakhono kunye nobuchule, kunye nokuqonda ngokucokisekileyo imingeni ekhethekileyo kunye neemfuno zomsebenzi.Kubalulekile ukusebenza kunye nabachwethezi abanamava kunye nabaqinisekisiweyo abanokuvelisa ngokuqhubekayo iiwelds ezikumgangatho ophezulu ezihlangabezana nemigangatho engqongqo yeshishini.

Ukuqukumbela, i-spiral welded tube arc welded umbhobho wegesi yendalo licandelo eliphambili kushishino lwemibhobho.Kudinga uqwalaselo olucokisekileyo lweendlela zokuwelda, izixhobo zokuzalisa, kunye neziqinisekiso ze-welder owenza umsebenzi.Ngokuqinisekisa ukuba le miba ifumana ingqwalasela efunekayo, kuya kwenzeka ukwenza imibhobho yegesi yendalo ehlangabezana neemfuno zoshishino lokhuseleko, ukuthembeka kunye nokusebenza kwexesha elide.
