1. Iyini inhloso yokufakwa kwensimbi?
Impendulo: ①Yehlisa ubulukhuni bensimbi futhi uthuthukise ipulasitiki, ukuze kube lula ukusika nokucutshungulwa kokwakheka okubandayo;②Cwenga okusanhlamvu, ukufana kokwakheka kwensimbi, thuthukisa ukusebenza kwensimbi noma lungiselela ukwelashwa kokushisa okuzayo;③Susa okusele ensimbi Ukucindezeleka kwangaphakathi ukuze uvimbele ukuwohloka nokuqhekeka.
2. Kuyini ukucisha?Iyini inhloso yawo?
Impendulo: Inqubo yokwelapha ukushisa yokushisisa ucezu lwensimbi kuzinga lokushisa elithile ngaphezu kwe-Ac3 noma i-Ac1, luyigcine isikhathi esithile, bese luyipholisa ngesivinini esifanelekile ukuze kutholwe i-martensite noma i-bainite ibizwa ngokuthi i-quenching.Inhloso ukwandisa ubulukhuni, amandla kanye nokugqoka ukumelana kwensimbi.
3. Yiziphi izinzuzo kanye nokubi zokushisela i-arc manual?
Impendulo: A. Izinzuzo
(1) Inqubo iyavumelana nezimo futhi ivumelana nezimo;(2) Izimfanelo zinhle;3) Kulula ukulawula deformation futhi ngcono ukucindezeleka ngokusebenzisa inqubo ukulungiswa;(4) Imishini ilula futhi kulula ukuyisebenzisa.
B. Okubi
(1) Izidingo zabashiseli ziphezulu, futhi amakhono okusebenza nolwazi lwabashiseli kuthinta ngqo ikhwalithi yemikhiqizo.
(2) izimo zokusebenza ezimbi;(3) ukukhiqiza okuphansi.
4. Yiziphi izinzuzo kanye nokubi kwenqubo ye-arc welding engaphansi kwamanzi?
Impendulo: A. Izinzuzo
(1) Ukusebenza kahle kokukhiqiza okuphezulu.(2) Ikhwalithi enhle;(3) Yonga izinto kanye namandla kagesi;(4) Ukwenza ngcono izimo zokusebenza futhi kunciphise umfutho wabasebenzi
B. Okubi
(1) Ifanele kuphela ukushisela indawo evundlile (ethambekele).(2) Kunzima ukushisela izinsimbi nama-alloys ane-oxidizing kakhulu njenge-aluminium ne-titanium.(3) Izinto zokusebenza ziyinkimbinkimbi kakhulu.(4) Uma i-current ingaphansi kuka-100A, ukuzinza kwe-arc akukuhle, futhi akufanelekile ukushisela amapuleti amancane anogqinsi olungaphansi kuka-1mm.(5) Ngenxa yokujula kwechibi elincibilikisiwe, izwela kakhulu ezimbotsheni.
5. Yiziphi izimiso ezijwayelekile zokukhetha umsele?
Impendulo:
① Ingaqinisekisa ukungena kwe-workpiece (ukujula kokungena kwe-arc welding yezandla ngokuvamile ingu-2mm-4mm), futhi ilungele ukusebenza kokushisela.
②Umumo wegroove kufanele kube lula ukuwucubungula.
③ Thuthukisa ukukhiqiza kokushisela futhi wonge izinduku zokushisela ngangokunokwenzeka.
④ Nciphisa ukuwohloka kwe-workpiece ngemuva kokushisela ngangokunokwenzeka.
6. Iyini i-weld shape factor?Buyini ubudlelwano bayo nekhwalithi yokushisela?
Impendulo: Ngesikhathi sokushisela i-fusion, isilinganiso phakathi kobubanzi be-weld (B) kanye nobukhulu obaliwe (H) be-weld engxenyeni ewela i-single-pass weld, okungukuthi, ф=B/H, ibizwa ngokuthi. i-weld form factor.I-coefficient ye-weld shape encane, iyancipha futhi ijulile i-weld, futhi ama-welds anjalo athambekele ekufakweni kwe-pore slag kanye nokuqhekeka.Ngakho-ke, isici somumo we-weld kufanele sigcine inani elithile.
7. Yiziphi izimbangela ze-undercut nendlela yokuvimbela?
Impendulo: Izimbangela: ikakhulukazi ngenxa yokukhethwa okungalungile kwemingcele yenqubo yokushisela, i-welding yamanje kakhulu, i-arc ende kakhulu, isivinini esingalungile sokuthutha kanye nezinduku zokushisela, njll.
Indlela yokuvimbela: khetha isivinini esilungile sokushisela kanye nesivinini sokushisela, i-arc ayikwazi ukwelulelwa ibe yinde kakhulu, futhi uphathe indlela efanele kanye ne-engeli yokuthutha umugqa.
8. Yiziphi izizathu nezindlela zokuvimbela usayizi we-weld surface ungahlangabezani nezidingo?
Impendulo: Isizathu siwukuthi i-groove angle ye-weldment ayilungile, igebe lomhlangano alilingani, isivinini se-welding asilungile noma indlela yokuthutha ye-strip ayilungile, induku ye-welding kanye ne-angle ayikhethiwe ngokungalungile noma ishintshiwe.
Indlela yokuvimbela Khetha i-engeli efanelekile ye-groove kanye nemvume yomhlangano;khetha kahle imingcele yenqubo yokushisela, ikakhulukazi inani lamanje lokushisela futhi wamukele indlela yokusebenza efanele kanye ne-engeli ukuze uqinisekise ukuthi ukuma kwe-weld kufana.
