Chete nekuziva pesvedzero yewelding nzira pane welding tinogona kushanda zvirinani uye kugadzirisa iyohigh-frequency longitudinal seam welded pombi kugadzira michinakuwana kubudirira kwepamusoro. Ngatitarisei kupesvedzerwa kwenzira dzewelding pane yakakwirira-frequency yakatwasuka seam welding pombi michina nhasi.
Pane nzira mbiri dzehigh-frequency welding: kubata welding uye induction welding.
Contact welding inoshandisa peya yemhangura maelectrodes akabatana nemativi ese epaipi yesimbi kuti isimbiswe. The induced current ine yakanaka kupinda. Izvo zviviri zvinokonzerwa ne-high-frequency current zvinowedzerwa nekuda kwekubatana kwakananga pakati pe electrode yemhangura uye ndiro yesimbi. Naizvozvo, iko kukwenenzverwa kwekubatisa welding kwakakwira uye ine simba shoma rekushandisa, rinoshandiswa zvakanyanya mukugadzirwa kwepombi dzinomhanya-mhanya uye dzakaderera-chaiyo, uye kubata welding kunowanzo kudiwa kana uchigadzira mapombi akakora esimbi. Zvisinei, pane zvipingamupinyi zviviri mukubatanidza welding: imwe ndeyokuti electrode yemhangura inosangana neplate yesimbi, uye inopfeka nokukurumidza; imwe yacho ndeyokuti nekuda kwekuita kwe flatness yesimbi yeplate pamusoro uye kutwasuka kwemupendero, kugadzikana kwemazuva ano kwekubatanidza welding kwakashata, uye mukati nekunze burrs ye weld yakakwirira. , Haiwanzo shandiswa kana welding yakakwirira-chaiyo uye yakatetepa-yakavezwa pombi.
Induction welding ndeyekuputira imwe kana anopfuura majana emainduction coils kunze kwepombi yesimbi kuti isungirwe. Mhedzisiro yeakawanda-inotendeuka iri nani pane imwe chete kutendeuka, asi zvakanyanya kuoma kugadzira nekuisa akawanda-turn induction coils. Kubudirira kwakakwirira kana chinhambwe pakati peiyo induction coil uye simbi pombi pamusoro idiki, asi zviri nyore kukonzeresa kuburitsa pakati peiyo induction coil uye pombi. Kazhinji, zvinokurudzirwa kuchengetedza gaka re5-8 mm pakati peiyo induction coil uye pamusoro pesimbi pombi. Paunenge uchishandisa induction welding, sezvo induction coil isingabatani nendiro yesimbi, hapana kupera uye kubvaruka, uye induction ikozvino yakadzikama, iyo inovimbisa kugadzikana kwewelding. Hunhu hwepamusoro hwepombi yesimbi panguva yewelding yakanaka, uye weld seam yakatsetseka. Kune chaiyo mapaipi, induction welding inonyanya kushandiswa.
