I-Aluminium rod butt welding iyinqubo esetshenziswa kabanzi ezinhlelweni ezihlukahlukene zezimboni, eyaziwa ngamandla ayo okudala ama-welds aqinile futhi ahlala isikhathi eside.Isici esisodwa esibalulekile sale nqubo ukushisa kwangaphambi kwesikhathi, okuhlanganisa ukukhuphula izinga lokushisa kwezinduku ze-aluminium ngaphambi kokuba zishiselwe ndawonye.Kulesi sihloko, sizohlola ukubaluleka kanye nezinzuzo zokushisa ngaphambili emishini yokushisela ye-aluminium rod butt.
1. Ukunciphisa Ukucindezeleka
Ukushisa kwangaphambi kwesikhathi kudlala indima ebalulekile ekwehliseni izingcindezi ezinsalela ezingase zenzeke ngesikhathi senqubo yokushisela.I-Aluminium, njengezinye izinsimbi eziningi, inomkhuba wokugoqeka futhi yandise njengoba ifudunyezwa futhi ipholiswa.Lapho izinti ze-aluminium zishiswa ngokushesha futhi zishiselwe ngaphandle kokushisisa, umehluko obalulekile wokushisa ungakhula ngaphakathi kwempahla.Lokhu kushisa okusheshayo nokupholisa kungaholela ekwakhekeni kokucindezeleka kwangaphakathi, okunganciphisa i-weld kanye nezinto ezizungezile.
Ngokushisa kuqala izinti ze-aluminium, lokhu kuhluka kwezinga lokushisa kuyancishiswa.Inqubo yokushisa kancane kancane ivumela ukusatshalaliswa kwezinga lokushisa okufanayo kulo lonke impahla.Ngenxa yalokho, i-weld joint kanye nezindawo ezizungezile zithola ukucindezeleka okuncishisiwe, okuholela ekushiseni okunamandla futhi okuthembekile.
2. Ukuvimbela Ukuqhekeka
I-Aluminium isengozini yokuqhekeka ngesikhathi senqubo yokushisela, ikakhulukazi uma kunezinguquko ezingazelelwe zokushisa.Ukushisa kuqala kusiza ukuvimbela ukwakheka kwemifantu ngokuqinisekisa izinga lokushisa elilawulwayo nelihamba kancane likhuphuka futhi lehle.Imifantu ingafaka engcupheni ubuqotho be-weld futhi inciphise amandla ayo, okwenza ukushisa kuqala kube isinyathelo esibalulekile ekugwemeni amaphutha okushisela.
3. Ukushisela Okuthuthukisiwe
Imishini yokushisela izinqe ze-aluminium ivamise ukusebenza ngamamaki ahlukahlukene nobukhulu bezinduku ze-aluminium.Ukushisa kuqala kungathuthukisa ukushisela kwalezi zinto ezihlukene ngokuthuthukisa izimo zenqubo yokushisela.Ivumela i-aluminium ukuthi ifinyelele izinga lokushisa lapho ikwazi ukwamukela khona ukushisa okushiselayo, okuholela ekuhlanganisweni okuthuthukisiwe phakathi kwezinduku.
4. I-Porosity Encishisiwe
Ukushisa kuqala kungasiza futhi ukunciphisa ukwakheka kwamaphakethe wegesi noma ama-voids ngaphakathi kwe-weld, eyaziwa ngokuthi i-porosity.Uma i-aluminiyamu ishiselwa ngokushesha, noma imaphi amagesi avaleleke, njenge-hydrogen noma umoya-mpilo, angase aphume obonakalayo, enze izikhala ekushiseleleni.Lawa ma-voids angawenza buthaka i-weld futhi ayeke ikhwalithi yawo.Ukushisa kwangaphambi kokushisa kunciphisa amathuba okuba negesi futhi kukhuthaze ukushisela okufanayo, okuqinile.
5. Amandla Ahlanganisiwe Athuthukisiwe
Ekugcineni, umgomo oyinhloko wokushisa ngaphambili ku-aluminium rod butt welding ukukhiqiza amandla aphezulu, ama-welds athembekile.Ngokunciphisa ukucindezeleka, ukuvimbela imifantu, ukuthuthukisa i-weldability, nokunciphisa i-porosity, ukushisa kwangaphambi kokushisa kunomthelela ekudalweni kwamalunga e-weld anezakhiwo eziphakeme zemishini.Lawa majoyinti akhombisa amandla anyukile, i-ductility, kanye nokumelana nokwehluleka, okuqinisekisa ukuthi ahlangabezana nezidingo eziqinile zezicelo ezahlukahlukene zezimboni.
Sengiphetha, ukushisa kuqala emishinini yokushisela i-aluminium rod butt kuyisinyathelo esibalulekile esithonya kakhulu izinga nokusebenza kwama-welds akhiqizwayo.Isebenza ukunciphisa ukucindezeleka, ukuvimbela imifantu, ukuthuthukisa weldability, ukunciphisa porosity, futhi ekugcineni ngcono amandla ahlangene.Ukufaka ukushisa kwangaphambi kwesikhathi enqubweni yokushisela kubalulekile ukuze kuzuzwe ukushiselwa kwenduku ye-aluminium okuhlala isikhathi eside futhi okunokwethenjelwa, okwenza kube indlela ebalulekile ezilungiselelweni eziningi zezimboni.
