Insimbi engagqwaliKubhekiswa enanini le-chromium eliphakeme kune-12% yensimbi, i-chromium endimeni yensimbi iyakwazi ukwakha ungqimba lwefilimu eliqinile le-CR2O3 ebusweni bensimbi, ukuze insimbi uqobo kanye nesivikelo kwi-corlosion. Ngalesi sisekelo, bese wengeza inani elithile le-NI, TI, NB, W nezinye izinto, zingakha ukumelana okukhethekile kokugqwala,Ukumelana nokushisa okuphezulu kwe-oxidation noma amazinga athile okushisa okushisa kanye nezinye izakhiwo zezinhlobo ezahlukahlukene zensimbi engenasici.
Insimbi engagqwali ngokushoKu-Microstructure yayo kungahlukaniswa izigaba ezinhlanu: Ferritic, Martensitic, Auntenitic, Auntenitic + Ferrite kanye nezulu Insimbi Engagqwali. Insimbi ye-auntenitic engagculi imvamisa ihlelwe njenge-aucen ehlala emazingeni okushisa asekamelweni, kanti ezinye ziyi-autenite + inani elincane le-ferrite, futhi la manani amancane okusiza eFerrite asiza ukuqhekeka okushisayo. Insimbi Engagqwali Engagqwali ngenxa yokusheshisa okuhle, embonini yamakhemikhali, iziqukathi zikaphethiloli kanye nezinye izimboni zisetshenziswa kabanzi.
Insimbi ye-auntenitic engagqwali ine-weldaality enhle, kepha lapho inqubo ye-welding noma inqubo ye-welding ingalungile, kuzokwenzeka amaphutha alandelayo: ukugqwala okwenzeka phakathi kokugqwala, ukuqhekeka kokugqwala kwengcindezelo.
Ngokusho kwezimpawu ezingenhla ze-welding zensimbi engenasici, ukuze uqinisekise ikhwalithi yokuhlangana, kufanele kusetshenziswe inqubo elandelayo ye-welding:
1. Ukulungiselela okwenziwe ngaphambi kokushiswa. Kuyadingeka ukususa zonke izinhlobo zokungcoliswa okungenza i-carbonilise insimbi ye-weld. Indawo ye-welding bevel nendawo ye-welding kufanele ibe ngamafutha futhi ifakwe emanzini ane-acetone noma utshwala ngaphambi kokufudumala. Amabhulashi ensimbi yensimbi ye-carbon ngeke asetshenziselwe ukuhlanza indawo ye-bevel kanye ne-weld. Ukususwa kokugqwala nokugqwala kufanele kube yigagasi egayayo, ibhulashi lensimbi engagqwali.
2. Ama-electrodes we-welding kumele agcinwe esitolo esihlanzekile. Lapho usebenzisa induku ye-welding kufanele ibekwe kwisilinda se-welding rod, ungathinta ngokuqondile isikhumba se-welding rod flux ngezandla zakho.
I-3. Iplatiti elincanyana le-welding kanye ne-bulderedment engagqwali yensimbi engenasici, ungakhetha induku ye-welding yohlobo lwe-titanium oxide. Ngoba i-arc yale electrode iqinile, futhi i-weld yakha kahle.
4 Ukuqina kwayo okusheshayo ngokushesha, insimbi ye-weld encibilike ingadlala indima ethile esekelayo.
I-5.
I-6. Enqubweni ye-welding, i-weldentiment kumele igcinwe emazingeni okushisa aphansi okuhlangene, mhlawumbe kungeqi ku-150 ℃.Insimbi engagqwaliUkushiswa kwe-Plate, ukuze kusheshiswe ukupholisa, kungafafazwa kusuka emuva kwe-Weld noma indawo ecindezelwe umoya wokushaya komhlaba, kepha umxhumanisi kufanele anake ukungcoliswa komoya okucindezelwe kwendawo ye-weld.
7 Ngenxa yenani lokumelana nensimbi engagqwali likhulu, eduze nendawo yokuphela kwesigaba se-electrode senzelwa indima yokuvimbela ukumelana nokubomvu, lapho ukujula kwe-wald kwe-fusion kuncishiswe, kepha ijubane lokuncibilika lishesha kakhulu futhi lizophumela ekunciphiseni kakhulu futhi kuzoholela nakwamanye amaphutha. Ukusuka ekuqinisekiseni ukumelana nokugqwala kokucatshangelwa okuhlanganyelwe, futhi kudinga futhi ukukhethwa kwe-welding encane yamanje, kunciphise ukufakwa kokushisa kwe-welding, ukuvikela ukweqiwa kwendawo eshiswe ukushisa eshiswe ukushisa.
8. I-Marlow Welding Path Technology kufanele isetshenziswe kubuchwepheshe be-Work lokusebenza, zama ukungafungi induku ye-welding lapho i-welding, futhi uthuthukise ijubane le-welding ngangokunokwenzeka ngaphansi kwesisekelo sokugcina umfungo omuhle.
9 Le filimu esigabeni esihlukile ikhona, imvamisa amakhompiyutha wensimbi axetic. Idlala indima yemidiya yensimbi neyokugqwala ihlukaniswe ngokuphelele neqhaza lokuvimbela ukuxhumana kwabezindaba zensimbi nangobuchule, ukuze insimbi iyeke ukuncibilika ukwakha isimo sokuvimbela ukukhulisa.
