1. Ukuhlaziywa kokushisela: 1. Cr18Ni9Ti insimbi engagqwaliФ159 mm×Ipayipi elikhulu elingu-12mm amajoyinti ezinqe ezivundlile asetshenziswa kakhulu ezintweni zamandla enuzi kanye nezinto ezithile zamakhemikhali ezidinga ukumelana nokushisa ne-asidi.I-welding inzima futhi idinga amalunga aphezulu okushisela.Indawo engaphezulu iyadingeka ukuthi ibunjwe, ibe ne-protrusions emaphakathi futhi ingabi nama-recesses.Ukuhlolwa kwe-PT ne-RT kuyadingeka ngemva kokushisela.Esikhathini esedlule, i-TIG welding noma i-arc welding yayisetshenziswa.Owokuqala unokusebenza kahle okuphansi kanye nezindleko eziphakeme, kanti lokhu kwakamuva kunzima ukukuqinisekisa futhi kunokusebenza kahle okuphansi.Ukuqinisekisa nokwandisa izinga, isendlalelo esingezansi sishiswe yi-TIG indlela yokugcwalisa ucingo lwangaphakathi nangaphandle, futhi i-MAG welding isetshenziselwa ukugcwalisa nokumboza ungqimba olungaphezulu ukuze ukusebenza kahle kuqinisekiswe.2. Izinga lokunwebeka okushisayo kanye nokuhamba kukagesi kwe-1Cr18Ni9Ti insimbi engagqwali kuhluke kakhulu kuleso sensimbi ye-carbon steel nensimbi ene-alloy ephansi, futhi ichibi elincibilikisiwe linoketshezi olubi kanye nokungakhiwanga kahle, ikakhulukazi uma kushiselwa kuzo zonke izindawo.Ngaphambilini, i-MAG (Ar+1%～2% O2) ukushisela insimbi engagqwali ngokuvamile yayisetshenziselwa ukushisela isicaba kanye nokushisela imicu eyisicaba.Enqubweni yokushisela i-MAG, ubude bocingo lokushisela bungaphansi kuka-10mm, i-amplitude yokushwibeka, imvamisa, isivinini, kanye nesikhathi sokuhlala sonqenqema sesibhamu sokushisela kuhlanganiswa kahle, futhi isenzo siyahlanganiswa.Lungisa i-angle yesibhamu sokushisela nganoma yisiphi isikhathi, ukuze unqenqema lwe-welding seam surface luhlanganiswe kahle futhi lwakhiwe kahle ukuze kuqinisekiswe ukugcwaliswa Kanye nosendlalelo sekhava.

2. Indlela yokushisela: Impahla ingu-1Cr18Ni9Ti, usayizi wepayipiФ159 mm×I-12mm, isisekelo senziwe ngokushisela i-argon arc manual, igesi exutshwe (CO2 + Ar) evikelekile yokushisela kanye nekhava yokushisela, ukushisela okuqondile nokuvundlile okugxilwe kuzo zonke izindawo.

3. Ukulungiselela ngaphambi kokushisela: 1. Hlanza uwoyela nokungcola, futhi ugaye indawo engaphansi kanye no-10mm oyizungezile ukuze uthole ukucwebezela kwensimbi.2. Hlola ukuthi amasekhethi amanzi, ugesi, negesi awavinjiwe yini, nezinto zokusebenza nezinye izinto ezisesimeni esihle.3. Hlanganisa ngokosayizi.I-tack welding ilungiswa yizimbambo (amaphoyinti ama-2, amaphuzu angu-7, namaphuzu angu-11 alungiswa yizimbambo), noma ku-groove positioning welding, kodwa naka ukuthungatha i-welding.
