I-welding yomoya oshushu ikwabizwa ngokuba yi-hot air welding. Umoya oxinzelelweyo okanye igesi ye-inert (ngokuqhelekileyo i-nitrogen) ifudunyezwa kwiqondo lokushisa elifunekayo ngokusebenzisa i-heater kwi-welding gun kwaye ifafazwe phezu kweplastiki kunye ne-welding strip, ukwenzela ukuba ezi zimbini zinyibilike kwaye zidibaniswe phantsi koxinzelelo oluncinci. Iiplastiki ezinochuku kwioksijini (ezifana ne-polyphthalamide, njl.njl.) kufuneka zisebenzise igesi engasebenziyo njengesixhobo sokufudumeza, kwaye ezinye iiplastiki zinokusebenzisa umoya ohluziweyo. Le ndlela isoloko isetyenziselwa ukuwelda iiplastiki ezifana ne-polyvinyl chloride, i-polyethylene, i-polypropylene, i-polyoxymethylene, i-polystyrene, kunye ne-carbonate.

Ukuwelda koxinzelelo olushushu kusebenzisa ukufudumeza kunye noxinzelelo ukucinezela ucingo lwentsimbi kunye nendawo yentsimbi kunye. Umgaqo kukwenza intsimbi kwindawo welding eplastiki zikhubazeke ngokufudumeza kunye noxinzelelo, kwaye kwangaxeshanye ukutshabalalisa umaleko oxide kujongano welding uxinzelelo, ukuze umphezulu uqhagamshelwano phakathi koxinzelelo welding ucingo kunye nentsimbi ifikelela atomic gravitational. uluhlu, ngaloo ndlela luvelisa umtsalane phakathi kweathom kunye nokuphumeza injongo yokudibanisa.
I-Hot plate welding ithatha i-plate-drawing structure, kwaye ubushushu bomshini wokufudumeza umatshini wokufudumala bugqithiselwa kwindawo ye-welding yeendawo eziphezulu kunye nezantsi zeplastiki zokufudumeza ngokufudumeza kombane. Umphezulu uyanyibilika, kwaye emva koko umatshini wokufudumeza urhoxiswa ngokukhawuleza. Emva kokuba iindawo zokufudumeza eziphezulu kunye nezisezantsi zifudunyezwe, iindawo ezityhidiweyo zixutywe, ziqiniswe, kwaye zidibaniswe zibe yinye. Umatshini wonke uyifom yesakhelo, equka iipleyiti ezintathu: itemplate ephezulu, itemplate ephantsi, kunye nethemplate eshushu, kwaye ixhotyiswe ngesikhunta esitshisayo, i-mold yeplastiki ephezulu kunye nesezantsi ebandayo, kwaye imowudi yesenzo yi-pneumatic control.
I-Ultrasonic metal welding isebenzisa amaza e-vibration aphezulu-frequency ukuhambisa kwimigangatho emibini yentsimbi ukuze idityaniswe. Phantsi koxinzelelo, imiphezulu yentsimbi emibini ikhuhlana enye kwenye ukuze yenze ukudibanisa phakathi kweeleya zemolekyuli. Izibonelelo zayo zikhawuleza, zigcina amandla, amandla aphezulu okuxutywa, ukuqhuba kakuhle, akukho zintlantsi, kwaye kufutshane nokulungiswa okubandayo; ukungalungi kwayo kukuba iindawo zetsimbi ezidibeneyo azikwazi ukutyeba kakhulu (ngokuqhelekileyo zingaphantsi okanye zilingana no-5mm), indawo ye-weld ayikwazi ukuba nkulu kakhulu, kwaye uxinzelelo luyafuneka.
I-laser welding yindlela esebenzayo kunye nechanekileyo ye-welding esebenzisa i-laser-high-energy-density laser beam njengomthombo wokushisa. Ngomnye wemiba ebalulekileyo yokusetyenziswa kweteknoloji yokulungisa izinto ze-laser. Ngokuqhelekileyo, i-laser beam eqhubekayo isetyenziselwa ukugqiba ukudibanisa kwezinto. Inkqubo yayo ye-metallurgical yomzimba ifana kakhulu ne-electron beam welding, oko kukuthi, indlela yokuguqula amandla igqitywe nge-"key-hole" isakhiwo. Iqondo lokushisa elilinganayo kwi-cavity li malunga ne-2500 ° C, kwaye ukushisa kudluliselwa kwindonga yangaphandle ye-high-temperature cavity ukuze kunyibilike isinyithi esijikeleze umgodi. I-keyhole igcwele i-steam yobushushu obuphezulu obuveliswa yi-evaporation eqhubekayo yezinto zodonga phantsi kwe-irradiation ye-beam.
I-beam ingena ngokuqhubekayo kwi-key hole, kwaye izinto ezingaphandle kwesitshixo zihamba ngokuqhubekayo. Njengoko i-boam ihamba, i-keyhole isoloko ikwimeko ezinzileyo yokuhamba. Isinyithi esityhidiweyo sigcwalisa isithuba esishiywe emva kokuba i-key hole isusiwe kwaye iyancipha, kwaye i-weld yenziwa.
I-Brazing yindlela ye-welding apho isithako esinyibilikisiweyo (i-brazing material) enendawo yokunyibilika esezantsi kuneendawo zokusebenza eziza kudityaniswa zifudunyezwe kwiqondo lobushushu elingaphezu kwendawo yokunyibilikisa ukuze libe nolwelo olwaneleyo lokuzalisa ngokupheleleyo isithuba phakathi kwezinto ezimbini zokusebenza nge-capillary. isenzo (esibizwa ngokuba kukumanzisa), kwaye ke ezi zimbini zidityaniswa emva kokuba ziqina. Ngokuqhelekileyo e-United States, amaqondo obushushu angaphezu kwe-800 ° F (427 ° C) abizwa ngokuba yi-brazing (i-soldering enzima), kwaye amaqondo angaphantsi kwe-800 ° F (427 ° C) abizwa ngokuba yi-soldering ethambileyo (i-soldering ethambileyo).
I-manual welding yindlela ye-welding eyenziwa nge-handheld welding torch, i-welding gun okanye i-welding clamp.
I-Resistance welding yinkqubo yokuvelisa kunye neteknoloji esebenzisa ukufudumeza ukujoyina isinyithi okanye ezinye izinto ze-thermoplastic ezifana neeplastiki. Yindlela ye-welding ngokufaka uxinzelelo ngokusebenzisa i-electrode emva kokuba i-workpieces ihlanganiswe kwaye isebenzisa ubushushu obuxhasiweyo obuveliswa ngumbane odlulayo kwindawo yoqhagamshelwano kunye nommandla okufutshane.
I-Friction welding yindlela yokudibanisa isigaba esiqinileyo esebenzisa amandla omatshini njengamandla. Isebenzisa ubushushu obuveliswa kukungqubana phakathi kobuso besiphelo sezinto zokusebenza ukwenza ukuba bafikelele kwimo yeplastiki, kwaye emva koko i-forging ephezulu isetyenziselwa ukugqiba i-welding.
I-Electroslag welding isebenzisa ubushushu obuxhasiweyo obuveliswa ngoku kudlula kwi-slag njengomthombo wobushushu ukunyibilikisa isinyithi sokuzalisa kunye nesiseko sezinto, kwaye emva kokuqina, uxhulumaniso oluqinileyo phakathi kwe-athomu zetsimbi lwenziwa. Ekuqaleni kwe-welding, i-welding wire kunye ne-welding groove i-short-circuited ukuqala i-arc, kwaye inani elincinci le-flux eqinile liyongezwa ngokuqhubekayo. Ubushushu be-arc busetyenziselwa ukunyibilika ukwenza i-slag engamanzi. Xa i-slag ifikelela kubunzulu obuthile, isantya sokutya socingo lwe-welding sonyuka, kwaye i-voltage iyancitshiswa, ukwenzela ukuba ucingo lwe-welding lufakwe kwi-slag pool, i-arc icinyiwe, kwaye inkqubo ye-electroslag welding ivuliwe. Electroslag welding ikakhulu ibandakanya ukunyibilika nozzle electroslag welding, non-kunyibilika nozzle electroslag welding, wire electrode electroslag welding, plate electrode electroslag welding, njl. I-weld kulula ukutshisa kakhulu, isinyithi se-weld sisakhiwo esirhabaxa sekristale, ubunzima bempembelelo buphantsi, kwaye i-weldment ngokubanzi idinga ukuba ibe yesiqhelo kwaye ipholile emva kwe-welding.
I-high-frequency welding isebenzisa ubushushu obuqinileyo bokumelana njengamandla. Ngexesha ukuwelda, ubushushu ukumelana eveliswa high-frequency yangoku kwi workpiece isetyenziselwa ukufudumeza umphezulu workpiece welding indawo ukuya kwimo etyhidiweyo okanye phantse iplastiki karhulumente, kwaye emva koko (okanye hayi) amandla okuphazamisayo isetyenziswa ukufezekisa ukubopha ngentsimbi.
Ukunyibilika okushushu luhlobo loqhagamshelwano olwenziwa ngokufudumeza amalungu kwindawo yawo (ulwelo) yokunyibilika.
