Izici ze-Welding zensimbi ye-auntenitic engagqwali: ukucindezelwa okunwebekile kanye notshani ngesikhathi senqubo ye-welding kukhulu kakhulu, kepha imifantu ebandayo ayibonakali. Akukho ukucima okuqinisayo okuqinile kanye nokuhlanza okusanhlamvu eWeld, ngakho amandla ashukumisayo e-weld aphezulu.
Izinkinga eziphambili ze-autenitutic yensimbi ye-welding: Ukuguqulwa okukhulu kwe-Welding; Ngenxa yezimpawu zayo zemingcele yokusanhlamvu nokuzwela kokungcola okuthile (s, p), kulula ukukhiqiza imifantu eshisayo.
Izinkinga ezinhlanu ezinkulu ze-welding kanye nezindlela zokwelashwa zensimbi ye-auntenitic engagqwali
01 Ukwakheka kweChromium Carbide kunciphisa amandla kaWeld ukumelana nokugqwala okuqhubekayo.
Ukugqwala kwenhlangano: Ngokusho komqondo we-chromium desicion, i-chromium carbide iqonde emingceleni yokusanhlamvu lapho indawo yeWeld ne-Held-athwele ifudunyezwa endaweni yokushisa ye-wedtization ye-450-850 ℃, okuholela ekulweni nokugqwala.
.
a. Yehlisa okuqukethwe kwe-carbon yensimbi eyisisekelo kanye ne-weld, bese wengeza izinto zokuqinisa i-ti, nb nezinye izinto ku-base zensimbi ukunikeza kuqala ukwakheka kwe-CR23C6.
b. Yenza i-Weld yakha ukwakheka kwesigaba esingu-Austan kanye nenani elincane leFerrite. Lapho kunenani elithile le-ferrite eWeld, okusanhlamvu kungahlanjululwa, indawo okusanhlamvu ingandiswa, futhi imbewu ye-chromium carbide ngeyunithi ngayinye yomngcele wokusanhlamvu ingancishiswa.
I-Chromium incibilika kakhulu kuFerrite. I-CR23C6 yakhiwa ngokukhethekile eFerrite ngaphandle kokubangela imingcele yokusanhlamvu e-Aucen ukuze ichithwe ku-chromium; Ukusakazeka kukaFerrite phakathi kwama-auten kungavimbela ukugqwala emngceleni wokusanhlamvu kuya kokungaphakathi.
c. Lawula isikhathi sokuhlala ekwameni kwamazinga okushisa. Lungisa umjikelezo we-welming thermal, finyeza isikhathi sokuhlala sika-600 ~ 1000 ℃ ngangokunokwenzeka, khetha indlela ye-welding ene-welding density ye-welded, bese usebenzisa i-argon great arc welding, futhi usebenzise ama-argon argon arc welding, unciphise ama-argon argon arc welding, bese unciphisa ama-arcon are-arc welding, futhi anciphise izikhathi zokugcina kanye nokuphela kokugcina ukugwema ukufudumeza okuphindaphindiwe, kanye nendawo yokuxhumana Nge-Complosomive Medium ngesikhathi sokufudumeza se-multilayer kufanele kufakwe ku-weldid kungokunokwenzeka.
d. Ngemuva kokufudumala, yenza ukwelashwa kwesixazululo noma ukuqina kokuzinza (850 ~ 900 ℃) nokupholisa komoya ukwenza i-carbide kukhokhiswe futhi isheshise ukufakwa kwe-chromium).
(2) Ukugqwala okwenziwe ngommese kwama-welds. Ngalesi sizathu, izindlela ezilandelayo zokuvimbela zingathathwa:
Ngenxa yekhono elinamandla elinamandla lekhabhoni, lizobe lihlukanisa emngceleni wokusanhlamvu ukuze wakhe izwe eliphakeme ngesikhathi senqubo yokupholisa, kanti uTi ne-NB ahlala ekristalu ngenxa yekhono eliphansi lekhono. Lapho iWeld ifudunyezwa futhi ekwanzweni kokushisa okuzwakalayo, i-carbon ephakeme izokwenziwa kwe-CR23C6 phakathi kwamakristalu.
a. Yehlisa okuqukethwe kwekhabhoni. Ngensimbi engagqwali equkethe izinto zokuzinza, okuqukethwe kwekhabhoni akufanele kudlule u-0.06%.
b. Sebenzisa inqubo yokufaka i-welding. Khetha okokufaka okushisa okuncane kwe-welding ukunciphisa isikhathi sokuhlala endaweni eshiswe ngokweqile ekushiseni okuphezulu, bese unaka ukugwema umphumela wokuzwakala kwezinga lokushisa 'ngesikhathi se-welding.
Lapho i-welding ephethwe kabili, i-weld yokuxhumana ne-conlososive kufanele ibe yi-weldid yokugcina (Lesi isizathu esenza ukuthi kube nokushiswa kwamapayipi abubanzi obukhulu odongeni Uma kungakwazi ukwenziwa, ukucaciswa kwe-welding kanye nokwakheka kwe-weld kufanele kulungiswe, bese uzama ukugwema indawo eshibhile ekuxhumaneni ne-Complosive Medium kuphinde kwashukunyiswa futhi kufudunyezwe.
c. Ukwelashwa okushisa ngemuva kokushisa. Yenza ikhambi noma ukwelashwa okusindayo ngemuva kokushiswa.
Ukuqhekeka kokugqwala kwengcindezelo
Izinyathelo ezilandelayo zingasetshenziswa ukuvikela ukwenzeka kokuqhekeka kokugqwala kwengcindezi:
a. Khetha izinto zokwakha kahle futhi ulungise ukwakheka kwe-weld. Insimbi ephakeme ye-chromium-nickel auntenitic yensimbi engenasici, i-silicon chromium-nickel auntenitic insimbi engagqwali, insimbi yensimbi engenasici, futhi i-weld-chritium ferrititic yensimbi engenacala, futhi i-weld kanye noFerrite.
b. Susa noma wehlise ukucindezelwa okusele. Ingasetshenziselwa ukucindezelwa okushisayo kwe-welding-expression, okufana umkhathi ovikelayo we-on-line ukwelashwa okukhanyayo kokungeniswa kokungeniswa kokungeniswa kwezithando nokwamukela umgomo wokufudumala. Isithando esikhanyayo se I-Hanao Tech (Seko Tech (Seko Imishini) ayidingi ukusabalalisa, kuthatha kuphela imizuzwana eyi-15 ukuyofinyelela ngokushesha izinga lokushisa elihle kakhulu. Ngasikhathi sinye, inokuqina komoya okuphakeme, okungavimbela ngempumelelo ukubuyela emuva komoya ngesikhathi sokukhulisa. Ipayipi eliveziwe le-weldelwed linesakhiwo sensimbi efanayo kanye nengcindezi yokuhlangana kwezingqinamba iba yincane. Ngaphezu kwalokho, izindlela zemishini ezinjengokukhazimula, ukudubula i-peening ne-hammeng kunganciphisa nokuxineka okusele komhlaba.
c. Idizayini yesakhiwo enengqondo. Ukugwema ukugxila okukhulu kwengcindezi.
