Izakhiwo kanye nezicelo ze-Argon-Hydrogen Mixtures ku-Welding
Izingxube ze-Argon-hydrogenbaye bathola ukunakwa okuphawulekayo emkhakheni we-welding ngenxa yezakhiwo zabo eziyingqayizivele kanye nohlu olubanzi lwezicelo. Lesi sihloko sihlose ukuhlola izici ezihlukahlukene zezingxube ze-argon-hydrogen futhi sixoxe ngokusetshenziswa kwazo ezinqubweni zokushisela. Ngokuqonda lezi zakhiwo kanye nezicelo, abashiseli bangathuthukisa izinqubo zabo zokushisela futhi bazuze ama-welds ekhwalithi ephezulu.
1. Izici Zengxube Ye-Argon-Hydrogen:
1.1 Okokufaka Ukushisa Okunyusiwe: Izingxube ze-Argon-hydrogen zinokusebenza okuphezulu kwe-thermal uma kuqhathaniswa ne-argon ehlanzekile. Lokhu kubangela ukwanda kokufakwa kokushisa ngesikhathi senqubo yokushisela, okuholela ekungeneni okuthuthukisiwe kanye nesivinini sokushisela ngokushesha.
1.2 Ukuzinza Kwe-Arc Okuthuthukisiwe: Ukwengezwa kwe-hydrogen ku-argon kuthuthukisa ukuzinza kwe-arc ngokunciphisa ukwehla kwamandla kagesi kuyo yonke i-arc. Lokhu kuvumela ukulawula okungcono kwenqubo yokushisela, ukunciphisa i-spatter nokuqinisekisa i-arc ezinzile kuyo yonke i-weld.
1.3 Igesi Yokuvikela Ethuthukisiwe: Izingxube ze-Argon-hydrogen zinikeza izici ezinhle kakhulu zokuvikela, ukuvimbela ukungcoliswa komoya we-weld pool. Okuqukethwe kwe-hydrogen kule ngxube kusebenza njengegesi esebenzayo, isusa ngempumelelo ama-oxide nokunye ukungcola endaweni yokushisela.
1.4 Indawo Ethinteke Ukushisa Eyehlisiwe (HAZ): Ukusetshenziswa kwezingxube ze-argon-hydrogen kubangela i-HAZ encane futhi ethinteke kancane uma iqhathaniswa namanye amagesi avikelayo. Lokhu kunenzuzo ikakhulukazi ezintweni zokushisela ezine-conductivity ephezulu ye-thermal, njengoba kunciphisa ukuhlanekezela futhi kuthuthukisa ikhwalithi yokushisela jikelele.
2. Ukusetshenziswa kwezingxube ze-Argon-Hydrogen ku-Welding:
2.1 I-Carbon Steel Welding: Izingxube ze-Argon-hydrogen zivame ukusetshenziselwa ukushisela i-carbon steel ngenxa yekhono labo lokuhlinzeka ngokungena okujulile kanye nesivinini esiphezulu sokushisela. Ukuzinza kwe-arc okuthuthukisiwe kanye nezakhiwo zokuvikela ezithuthukisiwe zenza lezi zingxube zilungele ukuzuza ukushisela okuqinile nokuqinile ekusetshenzisweni kwensimbi ye-carbon.
2.2 I-Stainless Steel Welding: Izingxube ze-Argon-hydrogen nazo zifanelekile ukushisela insimbi engagqwali. Okuqukethwe kwe-hydrogen kule ngxube kusiza ekukhipheni ama-oxide angaphezulu, okuholela ekushiseleni okuhlanzekile ngokuncipha kwe-porosity. Ukwengeza, okokufaka okushisa okukhulayo kuvumela isivinini esisheshayo sokushisela, ukuthuthukisa ukukhiqiza ekwenziweni kwensimbi engagqwali.
2.3 I-Aluminium Welding: Nakuba izingxube ze-argon-helium zivame ukusetshenziselwa ukushisela i-aluminium, izingxube ze-argon-hydrogen nazo zingase zisetshenziswe. Lezi zingxube zinikeza ukuzinza okungcono kwe-arc kanye nesenzo sokuhlanza esithuthukisiwe, okuholela ekushiseleni kwekhwalithi ephezulu okunokukhubazeka okuncishisiwe.
2.4 I-Copper Welding: Izingxube ze-Argon-hydrogen zingasetshenziselwa ukushisela ithusi, zinikeze ukuqina okuhle kakhulu kwe-arc kanye nokufakwa okuthuthukisiwe kokushisa. Okuqukethwe kwe-hydrogen kule ngxube kusiza ukususa ama-oxide ethusi, kuqinisekise ukushisela okuhlanzekile nokuqinile.
Izingxube ze-Argon-hydrogen zinezakhiwo ezihlukile ezizenza zifaneleke kakhulu ekusetshenzisweni kokushisela okuhlukahlukene. Okokufaka kwabo okukhulayo kokushisa, ukuzinza kwe-arc okuthuthukisiwe, izakhiwo zokuvikela ezithuthukisiwe, kanye ne-HAZ encishisiwe kubenza babe ukukhetha okuhle kakhulu kwe-carbon steel, insimbi engagqwali, i-aluminium, kanye nokushisela ithusi. Ngokusebenzisa izingxube ze-argon-hydrogen, abashiseli bangakwazi ukuzuza ukushisela kwekhwalithi ephezulu ngokukhiqiza okuthuthukisiwe kanye nokukhubazeka okuncishisiwe. Kubalulekile ukuthi abashiseli baqonde izakhiwo kanye nokusetshenziswa kwezingxube ze-argon-hydrogen ukuze bathuthukise izinqubo zabo zokushisela futhi baqinisekise imiphumela eyimpumelelo kumaphrojekthi abo wokushisela.
