Ka lebaka la ho thatafala ho phahameng le brittleness ea li-alloys tse thata, ha ho bonolo ho tjheseletsa joalo ka lisebelisoa tse ling.Zhuzhou Chuangrui Cemented Carbide Co., Ltd.
Ka lebaka la phapang e kholo mesebetsing ea 'mele pakeng tsa tungsten carbide le carbon steel, brazing le ho hasanya welding e ntse e le mekhoa e ka khonehang le e sebetsang ea ho tjheseletsa.Ho feta moo, mekhoa e meng e mecha ea ho tjheseletsa e kang tungsten electrode inert gas maintenance arc welding (TIG), electron beam welding (EB-W), laser welding (LBW), joalo-joalo le eona e ntse e tšohloa le ho hlahlojoa ka matla, e ka sebelisoang tjheseletsa carbide ka samente nakong e tlang.
Brazing brazing ke mokhoa oa setso le o sebelisoang haholo ho cheseletsa carbide.Mekhoeng ea brazing ea carbide e entsoeng ka samente le tšepe, ho ea ka mokhoa oa ho futhumatsa, ho na le lelakabe la khase ea khase, sebopi sa sebōpi, sekontiri sa vacuum, brazing induction, ho hanyetsa brazing le tsebo ea laser brazing.Ka tsela efe kapa efe, ntlha ea ho qhibiliha ea tšepe ea tšepe e tlaase ho feta ea tšepe ea motheo 'me e ajoa ka lenonyeletso ka ho khahloa ke capillary.Lihlahisoa tse hokahaneng li kenyelletsa likotoana tsa ho cheka liliba tsa oli, litempe tse chesang le tse batang li shoa, liforomo tsa phofo ea metallurgy, li-roll, lisebelisoa tsa ho seha le lisebelisoa tsa ho metha, lisebelisoa tsa ho cheka majoe, lisebelisoa tsa ho betla lehong, joalo-joalo.
Brazing tšepe ke thepa ea ho tlatsa e sebelisoang ho tiisa, e phethang karolo ea bohlokoa mosebetsing oa motsoako oa brazing.Ts'ebetso ea solder ke e 'ngoe ea lintlha tsa bohlokoa tse khethollang boleng ba brazing.
Thepa ea khase ea khase e bonolo, e ka futhumatsoa le ho chesetsoa ka malakabe a mangata ho latela sebōpeho sa mosebetsi.Tšepe ea brazing hangata e entsoe ka tšepe e entsoeng ka tšepe e entsoeng ka filamentous kapa ea flake e thehiloeng ho koporo le silevera e thehiloeng ho silevera, e loketseng sehlahisoa se le seng le tlhahiso e nyenyane ea batch, empa khetho ea sebonela sa khase le phekolo ea mocheso ka mor'a brazing le lintho tse ling tse sa tsitsang li feta. , 'me boleng le ho tšepahala ha brazing li nyenyane.
Lihlahisoa tsa li-cutters tsa tungsten carbide bakeng sa brazing induction brazing, ho hanyetsa brazing le brazing ka sebōping li phahame, 'me boleng bo batla bo tsitsitse, empa lisebelisoa le litsebo li senyeha ho feta, tekanyo le sebōpeho sa workpiece e hlokahalang ho ba holimo, le vacuum brazing e ka fihlela boleng bo phahameng ba brazing, empa lisebelisoa li theko e boima ebile litsebo li thata
Joalo ka mofuta o mocha oa mohloli oa mocheso oa tjheseletsa, laser e na le litšobotsi tsa lebelo la ho futhumatsa ka potlako, sebaka se moqotetsane se amehileng ke mocheso, deformation ea post-welding le khatello e nyane ea masala, haholoholo ho fokolisa ho putlama ha sebaka sa fusion se kopaneng, se nang le melemo e tloaelehileng. e ne e boetse e sebelisoa ho cheselletsa carbide e entsoeng ka samente.Ka hona, ha u khetha mokhoa oa ho tjheseletsa, e lokela ho ba o loketseng haholo-holo, 'me hangata brazing ka sebōping se ka khotsofatsa kopo ea ho qhaqha.
(1)Tsela e qhalaneng
Vacuum dispersion welding le HIP dispersion welding li ka sebelisoa ho cheselletsa carbide e entsoeng ka samente.Ho welding ea vacuum dispersion welding, ho na le lintlha tse ngata tse amang boleng ba lenonyeletso, joalo ka sebopeho sa thepa, boleng ba sebaka se cheselitsoeng, tekanyo ea vacuum, data ea sandwich e bohareng, le sekhahla sa ho futhumatsa le ho futhumatsa. empa lintlha tsa bohlokoa ka ho fetisisa ke mocheso, khatello le nako.Matla a ho kuta a weld a atisa ho ntlafala ka ho eketsoa ha nako ea ho cheselletsa, hobane ho atolosoa ha nako ea ho cheselletsa ho ka etsa hore boholo ba li-micro-bumps holim'a metsi a marang-rang a nyamele, ho hlakile hore sebaka sa ho ama se eketsoa, ho hasana ha liathomo ho feta. e ngata, 'me sekhahla sa ho cheselletsa se ka ntlafatsoa haholo
(2) Tungsten khase ea inert tokiso arc welding
TIG welding, e le mokhoa o mocha oa ho koala carbide e entsoeng ka samente le tšepe, e ntse e le nakong ea liteko.
(3) Ho tjheseletsa beam ea elektrone
Electron beam welding e na le melemo ea matla a phahameng a futhumatsang, deformation e nyane kamora ho tjheseletsa, karo-karolelano e kholo ea bophara ba weld, le phetoho e pharalletseng ea liparamente tse tloaelehileng, 'me hobane ts'ebetso ea mocheso oa tjheseletsa e khuts'oane haholo, e ka fetoha mokhoa o mocha oa ho tjheseletsa. e tiisitsoeng ka carbide ka ho laola ho hasana ha dintho ho isa boholeng bo itseng.
