I-hot air welding ibizwa nangokuthi i-hot air welding. Umoya ocindezelweyo noma igesi ye-inert (imvamisa i-nitrogen) ifudunyezwa kumazinga okushisa adingekayo nge-heater kusibhamu esishiselayo bese ifafazwa phezu kwepulasitiki kanye nomugqa wokushisela, ukuze lezi zibili zincibilike futhi zihlanganiswe ngaphansi kwengcindezi encane. Amapulasitiki azwela umoya-mpilo (njenge-polyphthalamide, njll.) kufanele asebenzise igesi engenzi lutho njengendlela yokushisisa, kanti amanye amapulasitiki ngokuvamile angasebenzisa umoya ohlungiwe. Le ndlela ivame ukusetshenziselwa ukushisela amapulasitiki afana ne-polyvinyl chloride, i-polyethylene, i-polypropylene, i-polyoxymethylene, i-polystyrene, ne-carbonate.
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nezokusika - Imboni Yokushisela Nokusika YaseChina Nabahlinzeki (xinfatools.com)
I-Hot pressure welding isebenzisa ukushisisa nokucindezela ukuze ucindezele intambo yensimbi nendawo yokushisela yensimbi ndawonye. Isimiso siwukwenza insimbi endaweni yokushisela ikhubazekile ngokwepulasitiki ngokushisa nokucindezela, futhi ngesikhathi esifanayo ucekele phansi ungqimba lwe-oxide ku-interface welding welding, ukuze indawo yokuxhumana phakathi kwentambo yokushisela ingcindezi nensimbi ifinyelele amandla adonsela phansi e-athomu. ububanzi, ngaleyo ndlela ikhiqize ukukhangana phakathi kwama-athomu nokufeza inhloso yokubopha.
I-hot plate welding yamukela isakhiwo sokudweba ipuleti, futhi ukushisa komshini wepuleti lokushisa kudluliselwa endaweni yokushisela yezingxenye zokushisa zepulasitiki ezingaphezulu naphansi ngokufudumeza kukagesi. Ingaphezulu liyancibilika, bese umshini wepuleti lokushisa uhoxiswa ngokushesha. Ngemuva kokuthi izingxenye zokushisa ezingaphezulu neziphansi zishisiwe, izindawo ezincibilikisiwe ziyahlanganiswa, ziqiniswe, futhi zihlanganiswe zibe munye. Wonke umshini uyifomu lohlaka, ohlanganisa amapuleti amathathu: ithempulethi engenhla, ithempulethi ephansi, kanye nesifanekiso esishisayo, futhi ifakwe isikhunta esishisayo, isikhunta esibandayo sepulasitiki esiphezulu nangaphansi, futhi imodi yesenzo iwukulawula umoya.
I-Ultrasonic metal welding isebenzisa amaza okudlidliza anemvamisa ephezulu ukuze idlulisele ezindaweni ezimbili zensimbi ezizoshiselwa. Ngaphansi kwengcindezi, izindawo ezimbili zensimbi ziyagudlana ukuze zakhe ukuhlangana phakathi kwezingqimba zamangqamuzana. Izinzuzo zayo ziyashesha, zonga amandla, amandla e-fusion aphezulu, ukuhamba kahle, azikho izinhlansi, futhi eduze nokucubungula okubandayo; ukungalungi kwayo ukuthi izingxenye zensimbi ezishiselwe azikwazi ukushuba kakhulu (ngokuvamile zingaphansi noma zilingane no-5mm), indawo yokushisela ayikwazi ukuba nkulu kakhulu, futhi ingcindezi iyadingeka.
I-laser welding iyindlela yokushisela ephumelelayo nenembayo esebenzisa isigxobo selaser esinamandla amakhulu njengomthombo wokushisa. Kungenye yezici ezibalulekile zokusetshenziswa kobuchwepheshe bokucubungula izinto ze-laser. Ngokuvamile, i-laser beam eqhubekayo isetshenziselwa ukuqedela ukuxhumeka kwezinto. Inqubo yayo yomzimba ye-metallurgical ifana kakhulu ne-electron beam welding, okungukuthi, indlela yokuguqula amandla igcwaliswe ngesakhiwo "somgodi wokhiye". Izinga lokushisa elilinganayo emgodini lingaba ngu-2500 ° C, futhi ukushisa kudluliselwa odongeni olungaphandle lwembobo yokushisa ephezulu ukuze kuncibilike insimbi ezungeze umgodi. Imbobo kakhiye igcwele isitimu esinezinga eliphezulu lokushisa esikhiqizwe ukuhwamuka okuqhubekayo kwezinto zodonga ngaphansi kokushiswa kwemisebe.
I-beam ingena ngokuqhubekayo embotsheni kakhiye, futhi impahla engaphandle kwembobo kakhiye igeleza ngokuqhubekayo. Njengoba ugongolo luhamba, imbobo kakhiye ihlala isesimweni esizinzile sokugeleza. Insimbi encibilikisiwe ivala isikhala esisele ngemva kokuba imbobo kakhiye isusiwe futhi iyajiya, bese kwakhiwa i-weld.
I-Brazing iyindlela yokushisela lapho isigcwalisi esincibilikisiwe (impahla yokubrawuza) enephuzu elincibilikayo eliphansi kuneziqephu zokusebenza okufanele zixhunywe kushiselwa ezingeni lokushisa elingaphezu kwendawo yokuncibilika ukuze kwenze kube uketshezi ngokwanele ukugcwalisa ngokugcwele isikhala phakathi kwezinto zokusebenza ezimbili nge-capillary. isenzo (okuthiwa ukumanzisa), bese zombili zihlanganiswa ndawonye ngemva kokuba ziqinile. Ngokwesiko e-United States, amazinga okushisa angaphezu kuka-800°F (427°C) abizwa ngokuthi i-brazing (hard soldering), futhi amazinga okushisa angaphansi kuka-800°F (427°C) abizwa ngokuthi i-soldering ethambile (soldering ethambile).
Ukushisela ngesandla kuyindlela yokushisela eyenziwa ngethoshi yokushisela ephathwayo, isibhamu sokushisela noma i-welding clamp.
I-Resistance welding iyinqubo yokukhiqiza kanye nobuchwepheshe obusebenzisa ukufudumeza ukujoyina izinsimbi noma ezinye izinto ze-thermoplastic ezifana namapulasitiki. Kuyindlela yokushisela ngokusebenzisa ingcindezi ngokusebenzisa ama-electrode ngemva kokuba ama-workpieces ehlangene futhi kusetshenziswa ukushisa okuphikisayo okukhiqizwa ukudlula kwamanje endaweni yokuxhumana yejoyinti nendawo eseduze.
I-Friction welding iyindlela eqinile yesigaba sokushisela esebenzisa amandla emishini njengamandla. Isebenzisa ukushisa okukhiqizwa ukungqubuzana phakathi kobuso bokugcina bezinto zokusebenza ukuze zifinyelele esimweni sepulasitiki, bese i-forging ephezulu isetshenziselwa ukuqedela ukushisela.
I-Electroslag welding isebenzisa ukushisa kokumelana okukhiqizwa ukudlula kwamanje ku-slag njengomthombo wokushisa ukuze kuncibilike insimbi yokugcwalisa kanye nezinto eziyisisekelo, futhi ngemva kokuqina, kwakheka ukuxhumana okuqinile phakathi kwama-athomu ensimbi. Ekuqaleni kwe-welding, i-welding wire kanye ne-welding groove i-short-circuited ukuze iqale i-arc, futhi inani elincane le-flux eqinile liyangezwa ngokuqhubekayo. Ukushisa kwe-arc kusetshenziselwa ukuyincibilikisa ukwenza i-liquid slag. Lapho i-slag ifinyelela ekujuleni okuthile, isivinini sokudla socingo lwe-welding sanda, futhi i-voltage iyancishiswa, ukuze ucingo lwe-welding lufakwe echibini le-slag, i-arc icishiwe, futhi inqubo ye-welding ye-electroslag ivuliwe. Ukushisela i-Electroslag ikakhulukazi kuhlanganisa ukushiselwa kwe-nozzle encibilikayo ye-electroslag, ukushiselwa kwe-nozzle engancibiliki, i-electrode electroslag welding, iplate electrode electroslag welding, njll. i-weld kulula ukuyishisa ngokweqile, insimbi yokushisela iyisakhiwo esimahhadla secrystalline cast, ukuqina komthelela kuphansi, futhi ukushisela ngokuvamile kudinga ukwenziwa kujwayelekile futhi kufuthelane ngemuva kokushisela.
I-High-frequency welding isebenzisa ukushisa okuqinile kokumelana njengamandla. Ngesikhathi sokushisela, ukushisa kokumelana okukhiqizwe yi-high-frequency current ku-workpiece kusetshenziselwa ukushisa indawo yokushisela i-workpiece endaweni encibilikisiwe noma ecishe ibe yipulasitiki, bese (noma cha) amandla aphazamisayo asetshenziswa ukuze kuzuzwe ukubopha kwensimbi.
I-Hot melt uhlobo lokuxhuma olwenziwa ngokushisisa izingxenye endaweni yazo (ewuketshezi) yokuncibilika.
