Imishini yokushisela izinqe ze-aluminium idume ngamandla ayo okudala ama-welds aqinile futhi athembekile. Kodwa-ke, inkinga eyodwa evamile engathinta ikhwalithi yalezi zinsimbi ukuphuziswa kwezindawo zokushisela. Lokhu kubaphuzi, okuvame ukubangelwa i-oxidation, kungaphazamisa ubuqotho be-welds. Kulesi sihloko, sizohlola izindlela zokubhekana nokuvimbela ukuphuzi kwezindawo zokushisela emishini yokushisela yezinqe ze-aluminium.
1. Ukulungiselela Impahla Efanele
Ukuvimbela ukuphuzi kuqala ngokulungiselela impahla efanele. Qinisekisa ukuthi izinti ze-aluminum ezizoshiselwa zihlanzekile futhi azinakho ukungcola njengokungcola, amafutha, noma i-oxidation. Hlanza kahle izinto ezingaphezulu usebenzisa izindlela zokuhlanza ezifanele, njengokuxubha noma ukuhlanza amakhemikhali, ukuze ususe noma yikuphi ukungcola okungaholela ekushintsheni kombala.
2. Umkhathi olawulwayo
Enye indlela ephumelelayo yokuvimbela ukuphuzi ngesikhathi sokushisela ukudala umoya olawulwayo ozungeze indawo yokushisela. Lokhu kungafezwa ngokusebenzisa igesi ye-inert, njenge-argon, ukuvikela izindawo zokushisela kumoya-mpilo womkhathi. Ukuvikela igesi engenzi lutho kuvimbela i-oxidation futhi kusiza ukugcina umbala wemvelo we-aluminium.
3. Ukushisa kuqala
Ukushisa kuqala izinti ze-aluminium ngaphambi kokushisela nakho kungasiza ekwehliseni ukuphuzi. Ngokwandisa kancane kancane izinga lokushisa lezinduku, ukushisa kwangaphambi kwesikhathi kunciphisa ukunwetshwa okusheshayo nokufinyela okungaholela ku-oxidation yendawo. Ikhuthaza inqubo yokushisela ebushelelezi, inciphisa amathuba okuba phuzi.
4. Imingcele ye-Welding efanele
Imingcele yokushisela, kuhlanganise nesikhathi samanje, ingcindezi, nesikhathi sokushisela, idlala indima ebalulekile ekuvimbeleni ukuphuzi. Ukusebenzisa amapharamitha alungile wezinduku ezithile ze-aluminium ezishiselwe kuqinisekisa ukusatshalaliswa kokushisa okusebenzayo futhi kunciphisa ubungozi be-oxidation. Bheka izincomo zomkhiqizi mayelana nemingcele yokushisela efanele.
5. Ukuhlanza Nokwelashwa Kwangemva Kokushisela
Ngemuva kokushisela, kubalulekile ukuhlanza nokuphatha izindawo zokushisela ngokushesha. Susa noma yikuphi ukugeleza okusalayo noma ukungcola usebenzisa izindlela zokuhlanza ezifanele. Bese, cabanga ukusebenzisa ukwelashwa kwangemuva kokushisela, okufana nekhambi lokuhlanza eliqondene ne-aluminium noma into evikelayo, ukuze uvimbele ukuqhubeka kwe-oxidation nokubaphuzi.
6. Izinyathelo Zokuzivikela
Sebenzisa izinyathelo zokuvikela ukuvikela izindawo zokushisela emoyeni ozungezile ngesikhathi senqubo yokushisela. Lokhu kungabandakanya ukusetshenziswa kwamakhethini okushisela noma izihlangu ukuze kwakheke umgoqo onciphisa ukuchayeka kumoya-mpilo. Ukugcina indawo yokushisela ingenazo okusalungiswa nakho kungasiza ekugcineni indawo yokushisela ezinzile.
7. Ukugcinwa Kwezikhathi ezithile
Hlola njalo futhi ugcine umshini wokushisela, kufaka phakathi ama-electrode kanye nezingxenye zekhanda lokushisela. Noma yikuphi ukugqokwa noma ukulimala kulezi zingxenye kungaholela ekushiseleni okungahambisani nokwanda kwe-oxidation. Ukubhekana nalezi zinkinga ngokushesha kungasiza ekuvimbeleni ukuphuzi.
Sengiphetha, ukubhekana nokuvimbela ukuphuzi kwezindawo zokushisela emishinini yokushisela ye-aluminium rod butt kudinga inhlanganisela yokulungiswa kwempahla efanele, isimo sezulu esilawulwayo, ukushisa kwangaphambi kwesikhathi, nokunamathela kumingcele yokushisela efanele. Ukwengeza, ukuhlanzwa kwe-post-weld nokwelashwa, kanye nezinyathelo zokuzivikela kanye nokugcinwa kwesimiso, izinyathelo ezibalulekile zokugcina ubuqotho nokubukeka kwama-welds. Ngokulandela lezi zinqubo, ungaqinisekisa ukuthi imisebenzi yakho yokushisela i-aluminium rod butt ikhiqiza amashisela ekhwalithi ephezulu anombala omncane.
