Ngaphansi kwepayipi elishiselwe ukusuka phezulu kwe-arc, kusukela phezulu kuya phansi konke-isikhundla sokuthungatha, indlela yejubane lokushisela, ukubukeka kwe-weld, ikhwalithi enhle yokushisela, ungagcina izinto zokushisela, unciphise amandla omsebenzi, okuyi-SMAW evamile angeke aqhathaniswe futhi manje asetshenziswa kabanzi ekushiseleni amapayipi amabanga amade kuwo wonke amandla ekwakhiweni kweshubhu enezindonga ezincane ezinobukhulu obuncane obunobubanzi obuncane enenani elithile lokuphromotha.
Ngaphansi kokushisela ngokuvamile khetha i-welding yamanje efanele, i-electrode angle nesivinini sokushisela, iqonde ngokuhudulela phansi noma cindezela i-arcing swing kancane ukuze uqedele ukushisela. I-electrode evamile econsa iconsi yensimbi encibilikisiwe kanye ne-slag ngaphansi kombuzo, kanye nokusetshenziswa kwepayipi elinikezelwe kuma-electrode wokushisela, imininingwane ye-welding ephoqelelwe ngokuqinile, ungakwazi ukuxazulula lezi zinkinga. I-cellulose yohlobo lwe-electrode welding slag encane, i-arc force, ukuqina okwanele ukuvimbela i-slag encibilikisiwe futhi idonse phansi futhi ingene i-arc enkulu, ikakhulukazi ezitsheni ezinodonga oluqinile kanye nepayipi lensimbi elishiselwe lishaya phansi, ungakwazi ukuqeda ukusebenza kwefosholo lempande, ngaleyo ndlela uthuthukise umsebenzi. ukusebenza kahle, ukuthuthukisa izimo zokusebenza, kodwa ngenxa yokuqukethwe kwayo okuphezulu kwe-hydrogen ye-weld, ngakho-ke ekushiseni kwepayipi elinomfutho ophezulu wasekhaya osetshenziswa manje okuvame ukusetshenziswa i-cellulose electrode backing plus low hydrogen electrode kanye ne-filler cap surface welding.
Isethi efanele yamashubhu kanye ne-tack welding isekuqinisekiseni ikhwalithi ye-welding, ingemuva le-weld elihle liyisici esibalulekile. I-tack welding seam iyingxenye ye-formal, ayidingi nje ukwenza i-welding side, kodwa futhi nokuqinisekisa ikhwalithi yokushisela. Ubude be-welding obungama-20mm, ukujiya obungaba ngu-3mm, imithambeka ethambile ezinhlangothini zombili ze-weld kufanele igaywe ibe yisimo, ukuze kube lula ukuhlangana.
Eduze kwe-electrode yokushisela kubaluleke kakhulu ukusebenzisa i-engeli efanele. Ukusekela i-weld, ukugcwalisa kanye ne-capping rod angle ngokuyisisekelo kuyafana, kodwa ubude be-arc nokuthuthwa kwefomu elihlukile. Eduze kwe-weld, i-weld ilawulwa ubude nobubanzi bezinhlobo eziyinhloko zokuthutha i-arc, i-arc ne-arc ukunakwa okuseduze kwendawo engafanele kufanele kuvuleke.
