Okokuqala, ii-Welding cracks kunye neepores zenziwe.
Ukufuma okufunxwa yintonga ye-welding kuba yigesi phantsi kwesenzo sokushisa kwe-arc ye-welding, ebolisa i-hydrogen, okubangela ukubunjwa kwe-welding cracks kunye ne-pores.Oku kuyinyani ngakumbi kwi-alkaline electrode.Intonga ye-welding ivalwe ngeplastiki ye-polyethylene xa ipakishwe, kwaye ayikwazi ukuqinisekisa ubungqina obupheleleyo bexesha elide lokufuma.
Okwesibini, izalathisi ezahlukeneyo zeepropathi zoomatshini ziphantsi.

Indlela elula yokujonga imeko efumileyo yentonga ye-welding kwisiza:
(1) Khangela ukupakishwa kwentonga ye-welding.Ukuba ukupakishwa konakalisiwe, intonga ye-welding kufuneka ithathe umswakama ngokungathí sina.
(2) Beka iintonga zokuwelda ezimbalwa ezandleni zakho kwaye uziqengqe, kwaye iintonga zokuwelda ziphulukene nesandi esimnandi sesinyithi emva kokufunxa ukufuma.
(3) Thatha intonga ye-welding kwaye ugobe kancane nge-10-15 degrees.Ukuba kukho isandi esicacileyo sokuqhekeka xa ugoba, oko kuthetha ukuba intonga ye-welding iyomile.
(4) Thatha intonga ye-welding emhlabeni kwaye ujonge amandla ayo okugqama.Intonga eyomileyo inamandla angcono okugxuma kunye ne-rebound ephezulu.
(5) Xhuma i-electrode kwi-welding circuit kunye ne-short-circuit imizuzwana embalwa.Ukuba umphunga wamanzi ubonakala kumphezulu wengubo, i-electrode engeyomileyo.
(6) Thatha intonga ye-welding yokuvavanya ngokuthe ngqo.Ukuba yintonga ye-welding emanzi, i-coating iya kuqhuma okanye iwele kwiibhloko ngexesha lenkqubo ye-welding, kwaye ivelise umphunga wamanzi amaninzi.
(7) Jonga umphezulu wesiphelo se-welding core ukubona ukuba kukho umhlwa;unokunkqonkqoza kwi-coating kwaye ujonge ngokuthe ngqo ukuba i-welding core igqwalile.
(8) Khangela ngexesha lokusebenza kwe-welding, inkqubo yokusebenza ye-electrode emanzi iya kuba nolu tshintsho lulandelayo:
● Kwixabiso elifanayo langoku, amandla okuvuthela i-arc kuba mkhulu kwaye ubunzulu bokungena buyanda;
● Inani lokutshiza liyakhula kwaye amasuntswana abe makhulu;
● Kwi-electrodes ye-asidi, ukugubungela kwe-slag kubi, kwaye i-weld shape iba mbi;
● Kwi-electrode yohlobo lwe-hydrogen ephantsi, kukho imingxuma emincinci emininzi kwindawo yangaphakathi ye-slag (icala elidibene ne-weld).
