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. , kunye neradiation ngokwayo yomelele. 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 komoya, uxhotyiswe ngeeglavu zesikhumba, impahla, kunye nesigqubuthelo esizisebenzelayo sokuzimnyama.
(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 ngokubandakanya la manyathelo mane alandelayo: (1) ukuguqulwa kwamandla omatshini kumandla obushushu; (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 kwindawo yezinto ezimbini eziza kufakwa. 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.
