Izithombe zokushisela eziyishumi, i-XINFA izokwethula izindlela eziyishumi ezijwayelekile zokushisela, izithombe ezinyakazayo ezinembile, masifunde ndawonye!
1.Electrode arc welding
I-Electrode arc welding ingelinye lamakhono ayisisekelo ama-welders awazi kahle.Uma amakhono engasebenzi kahle, kuzoba namaphutha ahlukahlukene kumthungo oshiselwe, njengoba kuboniswe kuvidiyo yokufundisa elandelayo.
2.I-arc welding engaphansi kwamanzi
I-arc welding engaphansi kwamanzi iyindlela yokushisela esebenzisa i-arc njengomthombo wokushisa.Ngenxa yokungena okujulile kwe-arc welding engaphansi kwamanzi, ukukhiqiza kanye nekhwalithi yokushisela kuhle: ngenxa yokuvikelwa kwe-slag, insimbi encibilikisiwe ayihlangani nomoya, futhi izinga lokusebenza kwemishini liphezulu, ngakho kufanelekile. wokushisela ama-weld amade ezakhiwo zamapuleti aphakathi nendawo.
3.I-Argon arc welding
I-XINFA yabelana nawe ngezinyathelo ezimbalwa zokuphepha ze-argon arc welding:
(1) Inalithi ye-tungsten kufanele ilolwe njalo.Uma buthuntu, umsinga ngeke ugxile futhi uqhakaze.
(2) Uma ibanga eliphakathi kwenaliti ye-tungsten nomthungo wokushisela liseduze, lizonamathelana, uma likude, ukukhanya kwe-arc kuzoqhakaza, futhi uma sekuqhakazile, kuzoba mnyama, inaliti ye-tungsten izoba yimpandla. , futhi imisebe ngokwayo nayo inamandla.Kungcono ukusondela.
(3) Ukulawulwa kokushintshwa kuwubuciko, ikakhulukazi bokushisela ipuleti elincane, elingachofozwa kuphela futhi lichofozwe.Lona akuwona umshini wokushisela ozenzakalelayo onokunyakaza okuzenzakalelayo kanye nokudla okuzenzakalelayo kocingo.
(4) Ukuphakela ucingo, lunomuzwa wesandla.Intambo yokushisela yezinga eliphezulu inqunywa ebhodini le-304 ngomshini wokugunda.Ungayithengi iyinqwaba.Yiqiniso, ungathola ezinhle ezindaweni ezithengisa kakhulu.
(5) Zama ukusebenza ngaphansi kwezimo ezingenisa umoya, ezifakwe amagilavu esikhumba, izingubo zokugqoka, kanye nemaski e-automatic dimming.
(6) Ikhanda le-ceramic lethoshi lokushisela kufanele livikelwe ekukhanyeni kwe-arc, ikakhulukazi, umsila wethoshi lokushisela kufanele usondele ngangokunokwenzeka ebusweni bakho.
(7) Uma ungaba nomuzwa kanye nokuzingela mayelana nezinga lokushisa, usayizi, kanye nesenzo sokushintsha sechibi elincibilikisiwe, unguchwepheshe omkhulu.
(8) Zama ukusebenzisa izinaliti ze-tungsten ezimakiwe eziphuzi noma ezimhlophe, ezidinga ubuciko obuphezulu.
4.Ukushisela igesi
Ukushisela igesi (igama eligcwele: i-oxygen fuel gas welding, isifinyezo: OFW) iwukusebenzisa ilangabi ukushisisa insimbi nentambo yokushisela ekuhlanganyeleni kocwecwe lwensimbi ukuze luyincibilikise ukuze kuzuzwe inhloso yokushisela.Amagesi avuthayo asetshenziswa kakhulu ikakhulukazi i-acetylene, i-liquefied petroleum gas ne-hydrogen, njll., kanti igesi evame ukusetshenziswa kakhulu esekela ukuvutha umoya-mpilo.
5.Laser welding
I-laser welding iyindlela yokushisela ephumelelayo nenembayo esebenzisa isigxobo selaser esinamandla amakhulu njengomthombo wokushisa.I-Laser Welding ingenye yezinto ezibalulekile ekusetshenzisweni kobuchwepheshe bokucubungula izinto ze-laser.Ngawo-1970, yayisetshenziselwa kakhulu ukushisela izinto ezinezindonga ezincane kanye nokushisela okunesivinini esiphansi.Inqubo yokushisela i-heat conduction, okungukuthi, imisebe ye-laser ishisa ingaphezulu le-workpiece, futhi ukushisa okungaphezulu kusabalele ngaphakathi ngokusebenzisa ukushisa kokushisa.Ngokulawula ububanzi, amandla, amandla aphezulu kanye nemvamisa yokuphindaphinda kwe-laser pulse namanye amapharamitha ukuze kuncibilike ucezu lokusebenza bese kwakha ichibi elithile elincibilikisiwe.
6.I-Carbon dioxide evikela ukushisela
Abanye abashiseli abakhulu bacabanga ukuthi i-carbon dioxide shielded welding iyona elula, ngoba kulula ukuyisebenzisa nokufunda.Ngokuvamile, uma i-novice engakaze ixhumane ne-welding, uma inkosi imfundisa amahora amabili noma amathathu, ngokuyisisekelo i-position welding elula ingaqhutshwa.
Kunamaphuzu amaningana abalulekile ekufundeni i-carbon dioxide shielded welding: izandla eziqinile, okwamanje kanye ne-voltage eguquguqukayo, isivinini sokushisela esilawulekayo, ukuthinta komzimba, okungenziwa kahle ngokubuka amavidiyo amaningi, bese kuba yinkosi ukulandelana kokushisela, okungabamba ngaphezu kwesigamu umsebenzi wawucela.
7.Friction welding
I-Friction welding ibhekisela endleleni yokushisela ngokusebenzisa ukushisa okukhiqizwa ukungqubuzana kwendawo yokuxhumana ye-workpiece njengomthombo wokushisa ukuze udale ukuthi i-workpiece ibe ne-deformation yepulasitiki ngaphansi kwengcindezi.
Ngaphansi kwesenzo sokucindezela, ngaphansi kwesenzo sengcindezi eqhubekayo noma ekhulayo kanye ne-torque, ukunyakaza okuhlobene phakathi kwendawo yokuxhumana ye-welding kusetshenziselwa ukukhiqiza ukushisa kwe-friction kanye nokushisa kwe-plastic deformation endaweni yokungqubuzana nezindawo ezizungezile, ukuze izinga lokushisa izindawo ezizungezile zikhuphukela Ebangeni lokushisa eliseduze kodwa ngokuvamile liphansi kunephuzu lokuncibilika, ukumelana ne-deformation yezinto kuyancishiswa, i-plasticity iyathuthukiswa, futhi ifilimu ye-oxide esibonakalayo iphukile.Indlela ye-solid state welding efinyelela ukushisela.
I-Friction welding ngokuvamile iqukethe izinyathelo ezine ezilandelayo: (1) ukuguqulwa kwamandla kagesi abe amandla ashisayo;(2) ukuguqulwa kwepulasitiki kwezinto;(3) ukufaka ingcindezi ngaphansi kwe-thermoplasticity;(4) ukusabalala kwama-intermolecular kanye nokwenziwa kabusha kwekristalu.
8.I-Ultrasonic welding
I-Ultrasonic welding ukusetshenziswa kwamagagasi okudlidliza anemvamisa ephezulu ukuze adlulisele ezindaweni ezimbili ezizoshiselwa.Ngaphansi kwengcindezi, izindawo ezingaphezulu zezinto ezimbili ziyakhuhlwa zodwa ukuze zakhe ukuhlangana phakathi kwezingqimba zamangqamuzana.Izingxenye eziyinhloko ze-ultrasonic welding system zihlanganisa i-ultrasonic generator/transducer/horn/welding head triplet/mold and frame.
9.Ukusoda
I-Brazing iwukusebenzisa insimbi enendawo encibilikayo ephansi kunesisekelo sensimbi njenge-solder, ukushisa i-weldment kanye ne-solder ezingeni lokushisa elingaphezu kwendawo yokuncibilika ye-solder futhi ephansi kunezinga lokushisa elincibilikayo lesisekelo sensimbi, sebenzisa uketshezi. i-solder ukumanzisa isisekelo sensimbi, gcwalisa igebe phakathi kwamalunga kanye nendlela yokuxubanisa ngesisekelo sensimbi ukuze kubonakale ukuxhumana kokushisela.I-deformation ye-brazing incane, futhi inhlanganisela ibushelelezi futhi inhle.Ifanele ukunemba kwe-welding, eyinkimbinkimbi kanye nezingxenye ezakhiwe ngezinto ezihlukahlukene, njengamapuleti esakhiwo sezinyosi, ama-turbine blades, amathuluzi e-alloy aqinile namabhodi wesifunda aphrintiwe.Ngokuya ngokushisa kwe-welding, i-brazing ingahlukaniswa ngezigaba ezimbili.Uma izinga lokushisa lokushisisa i-welding lingaphansi kuka-450°C, libizwa nge-soldering ethambile, futhi uma lingaphezulu kuka-450°C, libizwa ngokuthi i-hard brazing.
