Ngaphantsi kombhobho odityanisiweyo ukusuka phezulu kwe-arc, ukusuka phezulu ukuya ezantsi yonke indawo-ubuchule bokuwelda, indlela yesantya se-welding, inkangeleko ye-weld, umgangatho olungileyo we-welding, unokugcina izinto zokuwelda, ukunciphisa ukuqina kwabasebenzi, okuyi-SMAW eqhelekileyo. ayinakuthelekiswa kwaye ngoku isetyenziswa ngokubanzi kwimibhobho yokuwelda yomgama omde kuyo yonke indawo yamandla kulwakhiwo lwetyhubhu enedayamitha ephantsi enodonga olubhityileyo inexabiso lokuthengisa.

Ngaphantsi kwe-welding ngokuqhelekileyo khetha i-welding yangoku efanelekileyo, i-angle ye-electrode kunye nesantya se-welding, ngokuthe ngqo ngokutsalela phantsi okanye ukucinezela i-arcing swing kancinane ukugqiba ukuwelda. I-electrode eqhelekileyo ithontsiza ithontsi yentsimbi etyhidiweyo kunye ne-slag phantsi kombuzo, kunye nokusetyenziswa kombhobho onikezelwe kwi-electrode ye-welding, iinkcukacha ze-welding zinyanzeliswe ngokungqongqo, unokusombulula ezi ngxaki. Iselulosi uhlobo electrode welding slag ngaphantsi, amandla arc, ukuqina ngokwaneleyo ukuze kuthintelwe slag otyhidiweyo kunye ukuthontsiza phantsi kwaye ingena arc enkulu, ingakumbi izikhongozeli ezishinyeneyo kunye nentsimbi edityanisiweyo umbhobho hit ezantsi, unako ukuphelisa ingcambu umsebenzi umhlakulo, ngaloo ndlela ukuphucula umsebenzi. ukusebenza kakuhle, ukuphucula iimeko zokusebenza, kodwa ngenxa yomxholo we-hydrogen ephezulu ye-weld, ngoko ke kwi-welding yasekhaya yoxinzelelo oluphezulu lwe-welding esetyenziswa ngoku ngokuqhelekileyo i-cellulose electrode backing kunye ne-electrode ephantsi ye-hydrogen kunye ne-filler cap surface welding.

Iseti efanelekileyo yeetyhubhu kunye ne-tack welding ekuqinisekiseni umgangatho we-welding, umva we-weld efanelekileyo yinto ebalulekileyo. Umthungo we-welding we-Tack uyingxenye ye-formal, ayifuni kuphela ukwenza i-welding side, kodwa nokuqinisekisa umgangatho we-welding. Ubude bewelding obuyi-20mm, ubukhulu obumalunga ne-3mm, amathambeka athambileyo kumacala omabini e weld kufuneka agutywe amile, ukuze kube lula ukuhlangana.
Ecaleni kwe-electrode ye-welding kubaluleke kakhulu ukusebenzisa i-angle echanekileyo. Ukuxhasa i-weld, ukuzaliswa kunye ne-capping rod angle ngokusisiseko kuyafana, kodwa ubude be-arc kunye nokuthuthwa kwefomu eyahlukileyo. Ecaleni kwe-weld, i-weld ilawulwa ngobude kunye nobubanzi beendlela eziphambili zokuthutha i-arc, i-arc kunye ne-arc ingqalelo esondeleyo kwindawo engafanelekanga kufuneka ivule.
