Oopopayi be-welding abalishumi, i-XINFA izakwazisa iindlela ezilishumi eziqhelekileyo zokuwelda, oopopayi abanomdla kakhulu, masifunde kunye!
1.Electrode arc welding
I-Electrode arc welding sesinye sezona zakhono zisisiseko ezenziwa ngabachwethezi.Ukuba izakhono azilawulwa kakuhle, kuya kubakho iziphene ezahlukahlukeneyo kwi-welded seam, njengoko kuboniswe kwividiyo yokufundisa elandelayo.
2.I-arc yokuwelda
I-arc welding ephantsi kwamanzi yindlela ye-welding esebenzisa i-arc njengomthombo wokushisa.Ngenxa yokungena okunzulu kwe-arc welding ephantsi kwamanzi, imveliso kunye nomgangatho we-welding ulungile: ngenxa yokukhusela i-slag, isinyithi esityhidiweyo asidibanisi nomoya, kwaye iqondo lokusebenza ngoomatshini liphezulu, ngoko lifanelekile. ukuwelda iiweld ezinde zezakhiwo zeepleyiti eziphakathi kunye nezityebileyo.
3.Argon arc welding
I-XINFA yabelana nawe ngamanyathelo ambalwa okukhusela kwi-argon arc welding:
(1) Inaliti yetungsten ifanele ilolwe rhoqo.Ukuba ibuthuntu, umsinga awusayi kugxila kwaye uqhakaze.
(2) Ukuba umgama phakathi kwenaliti ye-tungsten kunye ne-welding seam isondele, iya kunamathela kunye, ukuba ikude, ukukhanya kwe-arc kuya kuqhakaza, kwaye emva kokuba iqhakazile, iya kutshisa ibe mnyama, inaliti ye-tungsten iya kuba yimpandla. , kwaye i-radiation ngokwayo inamandla.Kungcono ukuba kufutshane.
(3) Ulawulo lokutshintsha lubugcisa, ngakumbi kwi-welding plate ebhityileyo, enokucofa kuphela kwaye icofe.Lo ayisiwo umatshini we-welding ozenzekelayo kunye nokunyakaza okuzenzekelayo kunye nokutya okuzenzekelayo ngocingo.
(4) Ukondla ucingo, lunesandla.I-high-grade welding wire inqunywe kwibhodi ye-304 ngomatshini wokucheba.Musa ukuyithenga ibe zizithungu.Ewe kunjalo, ungazifumana ezilungileyo kwiindawo ezithengiswayo.
(5) Zama ukusebenza phantsi kweemeko zokungena umoya, uxhotyiswe ngeeglavu zesikhumba, impahla, kunye nesigqubuthelo sobuso esizimelayo.
(6) Intloko ye-ceramic yetotshi ye-welding kufuneka ikhuselwe kwisibane se-arc, ngokukodwa, umsila wetotshi ye-welding kufuneka usondele kangangoko kunokwenzeka ebusweni bakho.
(7) Ukuba unokuba ne-intuition kunye ne-hunch malunga nobushushu, ubungakanani, kunye nentshukumo yokutshintsha kwedama elityhidiweyo, uligcisa eliphezulu.
(8) Zama ukusebenzisa iinaliti zetungsten ezityheli okanye ezimhlophe, ezifuna ubugcisa obuphezulu.
4.I-welding yegesi
Ukuwelda kwerhasi (igama elipheleleyo: ukuwelda kwegesi ye-oksijini, isifinyezo: OFW) kukusebenzisa idangatye ukutshisa isinyithi kunye nocingo lwe-welding kwindibaniselwano ye-workpiece yentsimbi ukuyinyibilikisa ukuphumeza injongo yokuwelda.Iirhasi ezitsha ezisetyenziswa ngokuqhelekileyo ziyi-acetylene, i-liquefied petroleum gas kunye ne-hydrogen, njl.
5.Laser welding
I-laser welding yindlela esebenzayo kunye nechanekileyo ye-welding esebenzisa i-laser-high-energy-density laser beam njengomthombo wokushisa.Ukuwelda kweLaser yenye yezinto ezibalulekileyo ekusetyenzisweni kobuchwepheshe bokusetyenzwa kwe-laser.Ngeminyaka yee-1970, yayisetyenziselwa ukuwelda izixhobo ezinodonga olucekethekileyo kunye nesantya esisezantsi sokuwelda.Inkqubo ye-welding kukuqhuba ubushushu, oko kukuthi, i-laser radiation ifudumeza umphezulu we-workpiece, kwaye ubushushu bomhlaba busasazeka ngaphakathi ngokuqhuba ubushushu.Ngokulawula ububanzi, amandla, amandla encopho kunye nokuphindaphinda ukuphindaphinda kwe-laser pulse kunye nezinye iiparameters ukunyibilikisa i-workpiece kunye nokwenza i-pool ethile etyhidiweyo.
6.Ikharbhon dayoksayidi ikhuselwe ukuwelda
Abanye oochwephesha abachwephesha bacinga ukuba icarbon dioxide ekhuselwe ukuwelda yeyona ilula, kuba yeyona ilula ukuyisebenzisa nokufunda.Ngokuqhelekileyo, ukuba i-novice engazange idibane ne-welding, ukuba inkosi imfundisa iiyure ezimbini okanye ezintathu, ngokusisiseko i-welding ye-position elula inokusebenza.
Kukho amanqaku aphambili aphambili ekufundeni i-carbon dioxide ekhuselwe ukuwelda: izandla ezizinzileyo, okwangoku kunye nombane, isantya esilawulekayo sokuwelda, izijekulo, ezinokulawulwa ngokubukela iividiyo ezingakumbi, kwaye emva koko ukwazi kakuhle ulandelelwano lwe-welding, enokuphatha ngaphezu kwesiqingatha umsebenzi wacela.
7.Friction welding
I-Friction welding ibhekisela kwindlela yokudibanisa ngokusebenzisa ubushushu obuveliswa yi-friction yendawo yoqhagamshelwano ye-workpiece njengomthombo wobushushu obangela ukuba i-workpiece ibe ne-deformation yeplastiki phantsi koxinzelelo.
Ngaphantsi kwesenzo soxinzelelo, phantsi kwesenzo soxinzelelo oluqhubekayo okanye olukhulayo kunye ne-torque, intshukumo ehambelanayo phakathi kwemiphezulu yokudibanisa i-welding isetyenziselwa ukuvelisa ubushushu be-friction kunye nobushushu beplastiki kwi-friction surface kunye neendawo ezingqongileyo, ukwenzela ukuba ubushushu iindawo ezijikelezileyo ziphakama ukuya Kuluhlu lweqondo lokushisa elikufutshane kodwa ngokuqhelekileyo liphantsi kunendawo yokuncibilika, ukuchasana kwe-deformation yezinto kuncitshisiwe, iplastiki iphuculwe, kwaye ifilimu ye-oxide kwi-interface iphukile.Indlela eqinileyo ye-welding efikelela kwi-welding.
I-Friction welding idla ngokuba nala manyathelo mane alandelayo: (1) ukuguqulwa kwamandla omatshini abe ngamandla ashushu;(2) ukuguqulwa kweplastiki kwezinto;(3) ukwenza uxinzelelo phantsi kwe-thermoplasticity;(4) i-intermolecular diffusion kunye ne-recrystallization.
8.I-Ultrasonic welding
I-Ultrasonic welding kukusetyenziswa kwamaza e-high-frequency vibration ukuze adlulisele kwiindawo ezimbini eziza kuxutywa.Phantsi koxinzelelo, imiphezulu yezinto ezimbini ikhuhlwa enye kwenye ukuze yenze ukudibanisa phakathi kweeleya zemolekyuli.Amacandelo aphambili e-ultrasonic welding system aquka i-ultrasonic generator/transducer/horn/welding head triplet/mold and frame.
9.Isoldering
Ukuxubha kukusebenzisa izinto zetsimbi ezinendawo yokunyibilika esezantsi kunesiseko sesinyithi njenge-solder, ukufudumeza i-weldment kunye ne-solder kwiqondo lobushushu elingaphezulu kunendawo yokunyibilika ye-solder kunye nezantsi kunobushushu obunyibilikayo besiseko sesinyithi, sebenzisa ulwelo. i-solder ukumanzisa isiseko sesinyithi, gcwalisa isithuba phakathi kwamalungu kunye nendlela yokudibanisa kunye nesiseko sesinyithi ukuqonda ukudibanisa kwe-weldment.I-deformation ye-brazing incinci, kwaye idibeneyo ilula kwaye inhle.Ilungele ukuchaneka kwe-welding, i-complex kunye namacandelo aqulunqwe ngezinto ezahlukeneyo, ezifana neepleyiti zesakhiwo se-honeycomb, ii-turbine blades, izixhobo ze-alloy ezinzima kunye neebhodi zesekethe eziprintiweyo.Ngokuxhomekeke kubushushu be-welding, i-brazing inokwahlulwa ibe ngamacandelo amabini.Ukuba ukushisa kwe-welding kuphantsi kwe-450 ° C, kubizwa ngokuba yi-soldering ethambileyo, kwaye ukuba iphezulu kune-450 ° C, ibizwa ngokuba yi-hard brazing.
