1. Izinyathelo zokulawula ukuguqulwa kwe-Welding
(1) Yenza ukuhlaziya okunengqondo nokubala kwesakhiwo, thola ukuwohloka kwe-welding kanye ne-shrinkage reserve, kanye nezingxenye ze-node eziyinkimbinkimbi, ukuncipha kwe-welding reserve kunganqunywa ngokuhlolwa.
(2) Lawula imvume yomhlangano
Lawula ngokuqinile ukunemba kokucutshungulwa kwe-bevel kanye nokuvunyelwa kwenhlangano, bese ukhetha umumo ofanele we-groove nokulandelana kokushisela ukuze unciphise ukuwohloka kokushisela.
(3) Sebenzisa uhlaka lwesondo olungaguquki
Hlanganisa ngokuhlanganisa okudingekayo kanye namafreyimu amasondo okushisela, izinto ezisetshenziswayo, izisekelo kanye namamajini okushwabana abekelwe.
(4) Yenza umhlangano ophelele ube yizicucu
Ukuze izingxenye eziyinkimbinkimbi, ngangokunokwenzeka emabhuloki, umhlangano jikelele Welding indlela yokukhiqiza.
I-Block-to-piece welding:
(5) I-Symmetrical ne-uniform welding
Ø Lapho i-weld plate groove eshiselwe ishiselwe, inani lama-turnovers liyenyuka ngokusho kwe-deformation, futhi i-welding isetshenziswa ngokulinganayo, nokulungiswa komlilo kule nqubo nakho kufaniswe.
Ø Uma ukusatshalaliswa kwe-weld kwengxenye kuhlobene nokusabalaliswa kwe-axisymmetric ye-geometrically neutral kwengxenye, ukushisela kwengxenye kusebenzisa i-symmetrical uniform welding ukuze kulungiswe ukuwohloka okuphelele kwengxenye ngokusebenzisa isimiso sokulinganisa.
Ø Ama-welds amabili ahlelwe ngokusho kwe-axis symmetry yendiza engathathi hlangothi ayalingana komunye nomunye ngendlela efanayo, ukucaciswa okufanayo, futhi ukushisela kwenziwa ngesikhathi esifanayo, ngalesi sikhathi, ukuncipha noma ukuguqulwa kwama-welds amabili alinganayo. eduze kwesiqondisindlela esime mpo se-eksisi engathathi hlangothi yendiza izobhalansisa futhi ikhansele ngaphandle.
Ø Ukuze ulinganise i-weld seam kwenye indiza elinganayo, i-weld seam kuzo zombili izindiza i-welding cross-welded, isiqondiso se-welding siyefana, ukucaciswa kuyafana, ukuze wonke ama-welds kufanele ahambisane ne-axis engathathi hlangothi ye-weld. ingxenye, ukuze ukuguquguquka okuphelele kwengxenye kulingane futhi kuncishiswe.
(6) Setha i-welding reverse deformation ngokusho kwezimpawu zokuhlangana
Ohlotsheni oluhlanganisiwe lwe-T olunobude obukhulu bepuleti lephiko, ukuncipha kwe-weld ngemva kokushisela kubangela ukuwa kwengxenye ye-outrigger ye-wing plate, kanye ne-preset welding reverse deformation ngaphambi kokukhiqizwa kuyindlela ephumelelayo yokushisela. lawula i-welding deformation.
A. Bala inani le-deformation noma i-engeli yengxenye enwetshiwe yepuleti lephiko ngokosayizi wokushisela (inani lokugcwalisa), inani lokunwetshwa kwepuleti lephiko, kanye nobukhulu bepuleti lephiko;
B. Hlanganisa i-welding ngemuva kokuguqulwa kwe-welding reverse yepuleti lephiko esethiwe ngokwenani elilinganisiwe lokuguquguquka elibaliwe;
C. Ngokuqina okushubile kwepuleti lephiko, ukukhiqizwa kwesikhunta esikhethekile sokugxiviza emshinini wokunyathelisa wamandla amakhulu kucindezelwe ngokuqondile ukulwa nokuguqulwa;ngemuva kokuphothulwa komhlangano ojwayelekile we-primer welding, indlela yokushisa ilangabi isetshenziselwa ukusetha kabusha i-welding anti-deformation ye-wing plate.
(7) Ukuhleleka kokushisela okunengqondo
Ukuze uthole ama-weld amade, ngaphansi kwemibandela evunyelwe isakhiwo, i-weld eqhubekayo kufanele ishintshwe ibe yi-weld ephakathi ukuze kuncishiswe ukuguquguquka;njengalapho ukushisela okungapheli kungavunyelwe, ukulandelana kwe-welding okunengqondo kufanele kukhethwe ukunciphisa noma ukukhansela omunye nomunye ngaphandle kwe-welding deformation.Indlela ye-Stepwise soldering, indlela ye-fractional stepwise soldering method, indlela ye-jump welding, indlela yokushintshanisa i-welding, kanye nendlela yokuhlanganisa ingxenye ye-symmetrical soldering ingamukelwa.
2. Ukulawula ukucindezeleka kwe-Welding kanye nezinyathelo zokuqeda
(1) Ukulawulwa kwengcindezi yokushisela
(1) Izinyathelo zokuklama
Ø Nciphisa inani lamashisela kanye nosayizi wokushisela esakhiweni.
Ø Ukuhlelwa kwe-Symmetrical of welds ukugwema ukugxila ngokweqile kwama-welds.
Ø Yamukela uhlobo lwelunga eliqinile kancane.
(2) Izinyathelo zenqubo
a.Yehlisa inani lokugcwalisa i-weld ukuze unciphise ukucindezeleka okusele kokushisela
Ø Yakha ngokunengqondo i-welding groove ye-joint plate ewugqinsi ukuze unciphise inani lokugcwaliswa kokushisela;
Ø Lawula ukunemba kokucubungula kanye negebe lokuhlanganisa le-groove, futhi ugweme ukwandisa inani lokugcwalisa i-welding;
Ø Lawula ipuleti eliwugqinsi le-T weld weld seam ukuze uqinise i-engeli yokushisela, gwema ukukhulisa inani lokugcwalisa i-welding.
b.Yamukela ukulandelana kokushisela okuphusile ukuze unciphise ingcindezi eyinsalela yokushisela
Ø Lapho ushisela engxenyeni efanayo, ukushisela kufanele kusetshenziswe ngendlela yokusabalalisa ukushisa nokusabalalisa okulinganayo ngangokunokwenzeka;
Ø Uma izingxenye zishiselwe, ukusuka ezindaweni ezilinganiselwe zezingxenye ukuya kwenye, kuya kulezo zikhundla ezinenkululeko enkulu yokunyakaza phakathi kwesinye;
Ø Setha i-margin ye-shrinkage ngokunengqondo kusenesikhathi, i-joint ene-shrinkage esobala izoshiselwa kuqala, futhi i-joint ene-shrinkage encane izoshiselwa kamuva, futhi i-welding kufanele ifakwe ngaphansi kwesithiyo esincane kunazo zonke.
c.Qinisekisa izinga lokushisa langaphambi kokushisa, izinga lokushisa eliphezulu nelincane le-interlayer ekushiseleni kufanele lilawulwe ngokuphumelelayo, kuncishiswe izinga lokubopha lejoyinti elishiselwe, kunciphise ukushisa okushisela okuthintekile kwebanga lendawo, futhi kunciphise ukucindezeleka okuyinsalela kokushisela kwejoyinti eliwugqinsi elishiselwe;
d.Yamukela izindlela zokushisela ezinengqondo, njengokuncibilika okujulile kokuncibilika, amandla amakhulu amanje, kanye nezindlela zokushisela ze-CO2 eziphumelelayo, ezinganciphisa inani lamashaneli okushisela futhi kunciphise ukubola kwe-welding kanye nokucindezeleka okusalayo;
e.Ukusetshenziswa kwesinxephezelo sokushisa indlela yokunciphisa ukucindezeleka ku-weld: enkambisweni yokushisela, ukushisa kolunye uhlangothi lwekhanda le-welding, ububanzi bokushisa abukho ngaphansi kuka-200mm, ukuze yona kanye nendawo yokushisela ngesikhathi esifanayo ikhule futhi inkontileka ngesikhathi esifanayo, ukuze kuzuzwe injongo yokunciphisa ukucindezeleka kokushisela.
f.Indlela yokusando yokunciphisa ukucindezeleka okusele kokushisela: ngemva kokushisela, isando sesandla esinobuso obuncane obuyindilinga sisetshenziselwa ukushaya indawo eseduze yomthungo we-weld, ukuze insimbi ye-weld kanye nendawo eseduze ye-seam inwetshwe futhi. ikhubazekile, esetshenziselwa ukunxephezela noma ukuvala ukuguqulwa kwepulasitiki yokucindezelwa okwenziwe ngesikhathi sokushisela, ukuze kuncishiswe ukucindezeleka kwensalela yokushisela.
