Insimbi engenasici angahlukaniswa izigaba ezine ngokuya ngesakhiwo sayo sensimbi, okungukuthi, insimbi engenasici, insimbi engenacala, insimbi engenacala, ne-auntenitic-Ferritic Dumplex Steel. Lokhu okulandelayo kuhlaziya izici ze-welding zensimbi ye-auntenitic yensimbi engenasici kanye nensimbi emibili engagqwali.
(1) Ukushiswa kwensimbi ye-auntenitic engagqwali
Insimbi ye-auntenitic engagqwali kulula ukuyivula ukwedlula ezinye izinsimbi ezingenasici. Akukho ukuguqulwa kwesigaba okwenzeka kunoma yiliphi izinga lokushisa, futhi akunangqondo ku-Hydrogen Embrittlement. Amalunga ensimbi angenasici ane-plastiki futhi ane-plastiki engcono nokuqina kwesimo se-welded. Izinkinga eziphambili ze-welding yilezi: Ukuqhekeka okushisayo okushisayo, ukufona, ukugqwala konhlangano kanye nokugqwala kwengcindezi. Ngaphezu kwalokho, ngenxa yokuvuselelwa okungesihle okushisayo, ukukhishwa okukhulu komugqa we-linear, ukucindezela okukhulu kwe-welding kanye nokuguquguquka. Lapho i-welding, ukufakwa kokushisa okushisa kwe-welding kufanele kube okuncane ngangokunokwenzeka, futhi akufanele kushaywe kusekwe kabusha, futhi izinga lokushisa lomhlangano kufanele lehliswe. Ukushisa kwe-interlayer kufanele kulawulwe ngaphansi kwama-60 ℃, futhi amalunga amaWeld kufanele athuke. Ukunciphisa ukufakwa kokushisa, ijubane le-welding akufanele lenyuswe ngokweqile, kepha kufanele liguqulwe ukuze linciphise i-welding yamanje.
(2) Ukushiswa kwe-auntenitic-Ferritic insimbi yesigaba ezimbili engenacala
Insimbi ye-Auntenitic-Ferritic Bidirectional Steressless Insimbi iyinsimbi engagqwali eyakhiwe nge-Aucen neFerrite. Kuhlanganisa nezinzuzo zensimbi ye-auntenitic nensimbi, ngakho-ke inezici zamandla aphezulu, ukumelana kahle nokugqwala nokushibilika okulula. Njengamanje, kunezinhlobo ezintathu ze-Dumplex Steel engenacala: CR18, CR21, kanye ne-CR25. Izici eziyinhloko zalolu hlobo lwe-welding yensimbi yilezi: Uma kuqhathaniswa nensimbi ye-auntenitic engagqwali, kunokuthambekela okuphansi okushisayo; Uma kuqhathaniswa nensimbi emsulwa engenacala, inokuthambekela okuphansi kokufona ngemuva kokufakwa ngemuva kokushiswa, kanye nezinga le-Ferrite Collening endaweni ethintekile yokushisa kwe-welding futhi ephansi, ngakho-ke i-weldurall ingcono.
Ngenxa yokusebenza okuhle kwe-welding kwalolu hlobo lwensimbi, ukusabalalisa nokushisa okuphezulu akudingekile ngesikhathi se-welding. Amapuleti amancanyana kufanele afakwe i-tig, namapuleti aphakathi naphakathi angafakwa nge-electrode arlc welding. I-electrode ekhethekile enokwakheka okufanayo ku-electrode yensimbi eyisisekelo noma ye-auntenitic enokuqukethwe okuphansi kwekhabhoni kufanele kukhethwe ku-electrode arlc welding. Ama-electroy asuselwa ku-alloy asuselwa ku-nickel angasetshenziselwa i-CR25 Dual-Phambilis Steel.
Ngenxa yokuba khona kwengxenye enkulu ye-Ferrite ku-Steel-Phambili Yesigaba Sokulwa, njengokuphambanisa kwe-Ferrititic Steel, okufana nokufakelwa kwe-aucedite okwenziwe ngo-475 ° C. Lapho ama-welding duplex ama-steress angenalutho ngaphandle kwe-NI noma ephansi ni, kunomkhuba wokuhlaselwa kwesigaba esisodwa kanye nokusanhlamvu endaweni ethintekile ekushiseni. Ngalesi sikhathi, kufanele kubhekwe ukuze kulawulwe okokufaka ukushisa okushisa, bese uzama ukusebenzisa isivinini esiphansi, esiphakeme se-welding, kanye nokushibilika okuncane kwe-welding. Futhi i-rel-pass welding ukuvikela ama-coarvening okusanhlamvu kanye nesigaba esisodwa se-ferrite endaweni ethintekile ekushiseni, izinga lokushisa phakathi kwezendlalelo akufanele libe liphezulu kakhulu, futhi kungcono ukwenqabela okulandelayo ngemuva kokubanda.
Zombili lezi zingenhla ziyizinhlobo ezilula ukuwela. Kodwa-ke, kukhona nezinhlobo zensimbi ezingenasici ezinokushiswa okumpofu, okufana noFerrite. Ngalesi sikhathi, sincoma ukuthi ucabangele ithuluzi lethu elisizayo lobunikazi-I-Electromagnetic Control ARC Stingilisization Student. I-Hanao Tech (Seko Tech (Seko Imishini) yafingqa isipiliyoni nemininingwane embonini yemishini yokukhiqiza amapayipi ebekiwe eminyakeni engama-20 eyedlule, ngakho-ke ngenkathi isivinini se-welding senziwe ngcono, futhi singabheka ikhwalithi ye-weld. Izinga leWeld liqinisekisiwe, kwathi lapho ipayipi elishayelwe lingena kwinqubo elandelayo yokucubungula, isilinganiso se-Scrap singancishiswa ngempumelelo futhi okukhishwa kungandiswa.
