deoxidizer ka monko o monate

Li-Deoxidizers ho Welding: Tataiso e Felletseng Li-welding li bohlokoa bakeng sa ho netefatsa litšepe tsa boleng bo holimo ka ho tlosa oksijene e qhibilihisitsoeng le litšila tse ling tšepeng e qhibilihisitsoeng. Tataiso ena e hlahloba mefuta e fapaneng ea li-deoxidizers ka ho cheselletsa, lits'ebetso tsa bona, le mekhoa e metle ea tšebeliso ea bona.

Ho utloisisa Karolo ea Li-Deoxidizers ho Welding

Oksijene e qhibilihisitsoeng ka tšepe e qhibilihisitsoeng e ka baka porosity, ho phunyeha le ho fokotsa thepa ea mochine. Li-deoxidizers ka ho cheselletsa itšoara ka litšila tsena tse qhibilihisitsoeng, ho etsa li-oxide tse tsitsitseng tse phaphametseng holim'a letamo la chese, li siea tšepe e hloekileng, e matla haholoanyane. Khetho ea deoxidizer itšetlehile ka tšepe botlaaseng, tshebetso tjheseletsa, 'me a lakatsa thepa tjheseletsa.

Mefuta ea li-deoxidizers

Lisebelisoa tse 'maloa li sebetsa e le tse atlehang li-deoxidizers ka ho cheselletsa. Mehlala e tloaelehileng e kenyelletsa: Silicon (Si): E sebelisoang haholo deoxidizer, e sebetsang ka ho khetheha litšepeng. E etsa silica e tsitsitseng (SiO2), e arohanang habonolo le tšepe e qhibilihisitsoeng. Palo ea silicon e kenyellelitsoeng e ipapisitse le maemo a oksijene le boleng bo lakatsehang ba weld. Manganese (Mn): E 'ngoe e tloaelehileng deoxidizer, hangata e sebelisoa hammoho le silicon. Manganese oxides le tsona li batla li tsitsitse ebile li arohane habonolo le letamo la weld. Aluminium (Al): Aluminium e matla deoxidizer, ho etsa alumina (Al2O3). E sebetsa ka ho khetheha ho tlosa oksijene ho li-alloys tsa aluminium le litšepe tse ling tse khethehileng. Titanium (Ti): Titanium e matla deoxidizer seo se sebetsa haholo le maemong a tlase. E sebelisoa hangata lits'ebetsong tse sebetsang hantle tsa welding tse hlokang bots'epehi bo ikhethang. Ferroalloys: Tsena ke li-alloys tse nang le likarolo tse ngata tsa deoxidizing tse kang silicon, manganese, aluminium le titanium. Ba fana ka mokhoa o bonolo oa ho hlahisa li-deoxidizer tse ngata ka nako e le 'ngoe.

Ho khetha Deoxidizer e nepahetseng

Khetho e nepahetseng deoxidizer e bohlokoa bakeng sa ho fihlela boleng bo lakatsehang ba weld. Lintlha tse lokelang ho nahanoa li kenyelletsa: Sebopeho sa Metal ea Motheo: Lisebelisoa tse fapaneng tsa motheo li na le likamano tse sa tšoaneng bakeng sa oksijene, tse hlokang li-deoxidizers tse fapaneng le likhakanyo. Mokhoa oa ho Welding: Mokhoa oa ho cheselletsa (mohlala, Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Shielded Metal Arc Welding (SMAW)) e susumetsa boemo ba ho pepeseha ha oksijene, ka lebaka leo, litlhoko tsa deoxidizer. Thepa e lakatsehang ea Weld: Thepa e hlokahalang ea mochini, joalo ka matla a thata le ductility, e tla laela se nepahetseng. deoxidizer le ho tsepamisa mohopolo oa eona.

Mekhoa e metle ea ho sebelisa li-deoxidizers

Tšoaro e nepahetseng le ts'ebeliso ea li-deoxidizers ka ho cheselletsa li bohlokoa bakeng sa liphetho tse sebetsang. Likarolo tsa bohlokoa li kenyelletsa: Tekanyo e Nepahetseng le Keketso: Taolo e nepahetseng holim'a palo ea deoxidizer Ho eketsoa ho bohlokoa ho qoba deoxidation e feteletseng, e ka lebisang liphellong tse sa rateheng. Ho kopanya ka nepo: Ho kopanya ka ho feletseng deoxidizer ka har'a letamo la weld e qhibilihisitsoeng ho netefatsa deoxidation e ts'oanang. Khetho ea Flux: Phallo e nepahetseng e ka ntlafatsa katleho ea deoxidizer ka ho thusa ho tlosa li-oxide. Tlhahlobo ea Post-Weld: Mekhoa ea tlhahlobo ea pono le tlhahlobo e sa senyeheng (NDT) ea hlokahala ho netefatsa boleng ba weld le ho netefatsa hore deoxidation e lekaneng e finyeletsoe.
