Kune zvigadzirwa zvine simende ye carbide composite, welding inowanzoshandiswa kugadzirisa maitiro, asi kazhinji zvishoma kusava nehanya, zviri nyore kugadzira mitswe yewelding, zvichiita kuti chigadzirwa chiraswe, uye zvese zvakambogadziriswa zvichadonha.Naizvozvo, zvakakosha kuti unzwisise zvikonzero zvekutsemuka mune simende carbide welding uye kudzivirira kuputika kutsemuka.Nhasi, mupepeti weChuangrui Technology achataura newe nezve zvikonzero zvekutsemuka kwecarbide welding, uye kukupa imwe referensi.
Mune welding, zvinhu zvakasiyana-siyana zvichave nemhando dzakasiyana dzekushongedza.Nekuziva chete mhando yezvishandiso zvinosungirirwa tinogona kunyatso gadzira chirongwa chekuvaka welding, kuitira kuti tisarudze nzira chaiyo yekuita kuti ive nechokwadi chemhando yewelding.Zvikonzero zvekutsemuka kwecemented carbide welding zvinonyanya kuongororwa kubva pane zvinotevera zvinhu.
Kutanga, inotarwa nehunhu hwesimende carbide Cai Laoda.Sezvatinoziva tese, kuomarara kwesimbi yewelding inotsamira pane kabhoni chinhu chiri muzvinhu.Nekuwedzera kwekabhoni yemukati, kuomarara kuchawedzera zvinoenderana, uye chokwadi tsika yekutsemuka inogadzirwa panguva yewelding ichawedzerawo.Nokudaro, simende ye carbide welding inowanzoita kuputika.
Chechipiri, kana simende carbide yakasungwa, kana ichienzaniswa nekabhoni simbi yakaderera, kupisa kwayo kunopisa kunokanganisa nzvimbo inotarisana neyakaomeswa dhizaini, iyo inonyanya kunzwisiswa neiyo hydrogen element muwelding, uye iyo welded joint yecemented carbide inogona kumira zvakanyanya. mitswe inowanzoitika.Pasi peiyo welding kupisa kutenderera, iyo microstructure uye zvimiro zvekupisa zvakakanganisika nzvimbo yeweld shanduko, nekudaro zvichiwedzera tsika yekugadzira crack.
Chechitatu, iyo embrittlement ye yakanyanyisa dhizaini munzvimbo yekupisa yakakanganisika yejoini yakashongedzwa inotungamira kune kuitika kwekutsemuka kwewelding.Izvi zvinonyanya kuenderana neiyo simende carbide huni kuumbwa uye welding kupisa kutenderera, izvo zvinozokanganiswa nepamusoro tembiricha yekugara nguva uye kutonhora kwedziva rakanyungudutswa panguva yewelding.
Izvo zviri pamusoro pane zvikonzero zvakati kuti nei simende ye carbide welding ichikonzera kutsemuka.Pakuputira zvinhu zvakadaro, zvinodikanwa kusanganisa hunhu hwewelding hwezvinhu kuti usarudze nemazvo zvinhu zvewelding, kugadzirira pamberi uye mushure mekugadzira, kunyatsotevedzera maitiro ekuita, uye kusimbisa iyo welding process.Preheating, post-weld kuchengetedza kupisa uye kupisa kurapwa zvakakosha kudzivirira kuitika kwecemented carbide welding cracks.
Cemented carbide yakaoma uye yakaoma.Kuregeredza kushoma mune welding process kuchaita kuti kukweshwa nekuda kwekutsemuka.Naizvozvo, isu tinofanirwa kuita gadziriro dzakakwana kana welding simende carbide.Maitiro ekugadzirisa kudzivirira kutsemuka kwechikafu.
