I-Anealing Idingeka Nini Emishinini Yokushisela Izinqe?

I-Annealing iyinqubo ebucayi embonini yokushisela, ikakhulukazi emishinini yokushisela izinqe. Lesi sihloko sidingida ukubaluleka kokudonsa, izinzuzo zako, kanye nezimo lapho kudingeka khona ukwenza lokhu kwelashwa kokushisa. Ukuqonda ukuthi kufanele ufake nini i-annealing kuqinisekisa ukukhiqizwa kwamajoyinti ashiselwe asezingeni eliphezulu anezakhiwo ezithuthukisiwe zemishini.

Isingeniso: I-Annealing iyindlela yokwelapha ukushisa ehlanganisa ukushisisa insimbi ezingeni lokushisa elithile bese ipholisa kancane kancane ukuze iguqule isakhiwo sayo esincane. Emishinini yokushisela i-butt, i-annealing idlala indima ebalulekile ekwehliseni izingcindezi ezinsalela, ukuthuthukisa i-ductility, kanye nokwenza ngcono ikhwalithi yokushisela iyonke.

1. Izinto Eziwugqinsi futhi Ezinamandla Aphakeme: Kumapuleti ensimbi awugqinsi noma izinto ezisebenza ngamandla amakhulu, ukupholisa ngokushesha ngesikhathi sokushisela kungabangela ubulukhuni nokuqina, okuholela ezinkingeni ezingase ziqhekeke. Ezimweni ezinjalo, i-annealing iyadingeka ukuze kubuyiselwe i-ductility kanye nokuqina kwento.
2. Ukunciphisa Ingcindezi: Ukushisela kukhiqiza izingcindezi eziyinsalela endaweni ehlangene, okungase kubangele ukuhlanekezela noma ukusonteka kwezingxenye ezishiselwe. I-Annealing isiza ukukhulula lezi zingcindezi eziyinsalela, ithuthukise ukuzinza kwe-dimensional futhi ivimbele ukuhlanekezela.
3. Izindawo Eziqinile: Ngesikhathi sokushisela, ukushisa kwendawo kungadala izindawo eziqinile kunsimbi, kuthinte kabi ubuqotho be-weld. I-Annealing ithambisa lezi zindawo eziqinile, idale i-microstructure efanayo kulo lonke ukujoyina.
4. I-Post-Weld Heat Treatment (PWHT): Kwezinye izinhlelo zokusebenza, amakhodi namazinga athile angase adinge ukwelashwa kokushisa kwangemva kwe-weld (PWHT) ukuze kuqinisekiswe ubuqotho be-weld futhi kuhlangatshezwane nezidingo ezithile zemishini. I-Annealing ngokuvamile iyingxenye yenqubo ye-PWHT.
5. Ukulungiselela Ukushisela Okungeziwe: Ku-multi-pass welding, ikakhulukazi uma usebenzisa amasu okushisela ahlukene noma izinto zokugcwalisa, ukuhlanganisa phakathi kwamaphasi kungasiza ekuvimbeleni ukuqhekeka kwe-weld nokuqinisekisa ukuhlangana okuhle phakathi kwezingqimba.

Emishinini yokushisela izinqe, i-annealing iyithuluzi elibalulekile lokuthuthukisa ikhwalithi yamalunga ashiselwe kanye nokunciphisa ingozi yokukhubazeka nokwehluleka. Ukwazi ukuthi kufanele usebenzise nini i-annealing kubalulekile ukuze kuzuzwe izakhiwo ezifiselekayo zemishini, ekudambiseni izingcindezi ezinsalela, kanye nokuqinisekisa ubude bezinto ezishiselwe. Ngokuhlanganisa i-annealing enqubweni yokushisela uma kunesidingo, abashiseli bangakhiqiza ama-welds asezingeni eliphezulu futhi anokwethenjelwa, ahlangabezane namazinga emboni aqinile kanye nokulindelwe ngamakhasimende.
