Titanium: titanium welding (technology). Titanium iwelding argon

Xa eyama, imikhumbi, oomatshini, kwaye kwezinye namanye amashishini ezivelisa ezalathelwe onzima nobilis usebenzisa izinto zexabiso ezifana titanium. Kuhle hayi kuphela ubunzima esezantsi, kodwa ke into yokuba but is akukho ngeenkqubo umhlwa. Makhe sihlolisise oko kanye na titanium. titanium welding - ukuba kwakuhlaziya esinomdla isihloko ukuthetha malunga noku kwaye kuya kuxoxwa ngazo.

A bit kolwazi jikelele

thatha nje kwaye usebenzise isiziba titanium wafumana ezinqabileyo. Kudla kokuba pretreated. Kuyabonakala ukuba oko kudla phantsi iwelding. Kodwa ekubeni metal esebenzayo ibhekisela amalahle, iingcali ujongene nengxaki wentshabalalo umbandela kubushushu degrees 400 Celsius phantsi kwempembelelo umphunga wamanzi, ioksijini, ne-nitrogen. Ngokwawo, le nkqubo entsonkothileyo kakhulu, ekubeni kuyimfuneko ukuba athobele inani elikhulu kwimimiselo yobuchwepheshe, okanye naluphi na uhlobo welding efanelekileyo inkqubo yokuqulunqwa koMthetho sentsimbi. Kuyo nayiphi na imeko, namhlanje bafunda ukwenza titanium. titanium welding ikhutshwa phandle ngeendlela ezininzi:

• msebe electron;
• Arc ukubhobhoza;
• argon.

Okwangoku udume zonke iindlela, kodwa argon kunayo ukuwelda ngenxa yezizathu eziliqela, esiza kuxubusha kamva.

Titanium kunye aluminiyamu yayo

metal Active athunyelwa kwindalo ngokwaneleyo. Abaninzi bathi akwanelanga, kodwa ujonge ukuthelekisa. Kuyo nayiphi na imeko, isixa titanium kwi kuqweqwe ngaphezu ubhedu okanye bakhokele. Le metal ixesha elide kakhulu. Ngendlela esulungekileyo ifikelela amandla 337 MPA, kwaye ingxubevange umyalelo we-1 ukuya 250 MPA. Ingongoma ukunyibilika titanium - 1668 degrees Celsius.

Kwiqondo lobushushu eqhelekileyo, oko iyamelana umhlwa kwaye isebenza kwiindawo ezinobutshaba. Noko ke, xa amaqondo obushushu kufika kumgomo 400 Celsius iimpawu ukuqhuba ukuba ukwehla. Idityaniswe ngamandla ne-nitrogen iqale ukuba oxidized yi-oksijini kunye namanzi nomphunga, nto leyo enciphisa kanobom yayo. Kuyaphawuleka ukuba izinto akazange ukuthambekela nokuqhekeka eshushu ngexesha ukuwelda, kodwa nomnikelo walo kuba enkulu, ezehlisa iimpawu zobugcisa intsimbi kunye nomgangatho weld. Enyanisweni, siyaqonda kancinane ukuba titanium. titanium welding - nantsi into enye into ebangel 'umdla. Sazise kwaye siza sithethe.

features kwetheknoloji welding

Ngelo xesha langoku asikwazi ukuba titanium i nokunqaba kule okanye loo mveliso. Esebenza kakhulu abenzi naye mveliso eyahlukeneyo. Kodwa kufuneka kuqondwe ukuba titanium - kukho imichiza into esebenzayo. Oku kubonisa ukuba ukusetyenziswa iwelding eqhelekileyo ayamkelekanga. Isizathu kukuba ngexesha lokuwa ungcoliseko ngohlobo carbides kunye nitrides leyo ukunciphisa ukusebenza eziphathekayo.

Ngoko ke, i imeko ezisisiseko iwelding - bohlukaniswe ngokupheleleyo kwimeko-bume esingqongileyo. Ezi zezi: ioksijini, initrogen, hydrogen kunye nabanye. Ukongeza, umsebenzi welding kufuneka wenziwe ngesantya eliphezulu. zokufudumeza elide kwi yikristale emkhusaneni esandisa ingqolowa, nto leyo eyandisa kakhulu brittleness. Kuyo nayiphi na imeko, welding of titanium, nto leyo eza kuxoxwa nzulu ngakumbi ngezantsi iteknoloji - inkqubo entsonkothileyo umngeni. Kwaye ngoku makhe siye phambili.

Titanium iwelding argon

Argon uhlobo ukuwelda olu idumile kakhulu phakathi ochwepheshe emhlabeni. Oku kungenxa yokuba akukho akukho fluxes kunye electrode kusetyenziswa ngoko wenza imisebenzi iwelding yayisesona ezintsonkothileyo. Ngaphezu koko, indlela ukuze bafumane welds argon inxulumene iintlobo ezikumgangatho ophezulu we welding. Kunye netheknoloji itywina ezikumgangatho ophezulu ifunyenwe.

Asikwazi ngesimo emhlabeni argon welding. Ihlala yokuba kukho nekhono lokusingatha zombini izakhiwo ezinkulu kunye namalungu amancinane. Komphetho oku kunika umgangatho ofanayo. Ngaphezu koko, argon welding titanium kulungile into yokuba kunokwenzeka ukuba asebenze kwindawo yangoku encinane, kwaye ivumela ukuba weld izinto ukuba ubukhulu ka-0.5 mm. Argon unako ukubuyisela iinkcukacha ezilahlekileyo umthamo wazo.

welding of titanium kunye aluminium yayo: Technology

Umsebenzi kufuneka wenziwe yi uchwepheshe abaqeqeshiweyo kunye nezixhobo ezifanelekileyo. Ukongeza, le nkqubo multi-step. Onke amanyathelo kufuneka kuhlala loviwo kusekwa ulandelelwano wayesenza ngokuvisisana nemilinganiselo.

Isigaba sokuqala - wokulungiselela. Kweli nqanaba kuyimfuneko ukucoca umphezulu metal. Kubaluleke kakhulu ukuba ukususa ifilimu oxide. Imiphetho idla ngayo indlela oxyfuel. Into okanye workpiece eyenziwayo kunye fluorine kunye acid (zehydrochloric). Oku kufanele ukuba zigcinwe kubushushu rhoqo degrees 60 Celsius. Apha kubalulekile ukubonelela ukhuseleko ngenxa intsimbi iphathwa asabela kunye emoyeni esesibhakabhakeni zombini ngaphandle kwicala angasemva. Ukuza kuthi ga ngoku, ubhedu okanye intsimbi pads ezifanelekileyo ekufuneka emalifakwe omhlophe. Ukongeza kwamagqabi kuvunyelwa ukusetyenziswa visors zokuzikhusela kunye nemilomo ezizodwa.

Ngexesha lenkqubo iwelding

Le inkqubo ke ithabatha indawo kwi lwangoku rhoqo. Zisiza efakwe a Tungsten electrode okhethekileyo. Xa kufika metal wawumdibanisa arc yombane kwakhiwa echibini weld. Ubushushu kudla ufikelela 6 amawaka degrees Celsius.

Phantsi yengcinezelo titanium arc etyhidiweyo behambe noko. Kubonakala ukuba zisiza uyitshisa lekhefu. Oku kungathathwa iadvanteji yangcono kakhulu wajula amandla. Ngaphezu koko, njalo Impontshelwa argon, ebonelela ukhuseleko nxamnye sesichengeni ioksijini, nitrogen kunye nezinye izinto.

into enye

Malunga ne aphathwe titanium. welding Cold kubandakanya ukusetyenziswa wire lokufaka kuphela xa ubukhulu metal ungaphezulu kwe-1,5 mm. Ukuba Ebubanzini yi 10-15 mm, i welding oluqhutywa i arc sicatshulwa kwamanzi. Ukuba umsebenzi lwaqhutywa ngokugcinwa kweteknoloji, omhlophe akuyomfuneko ukwenza ukusuka zeBlack. Kuya kuba kwizinga anencasa ophezulu. iikhompawundi ezifana luphawulwa airtightness eliphezulu elide.

Arc welding kunye electron umqadi iwelding

Kwamanzi arc welding a ngokwentelekiso kutshanje. Le ndlela isekelwe izinto zokwambathisa ukusuka kokusingqongileyo lwangaphandle fluxes ezizodwa. Flux luhlobo yintlama. I kusetyenziswa kakhulu qho imbovane-Iintlobo zokuguqulwa. Le peculiarity le ndlela sikuko yokuba kwakunokwenzeka ukufezekisa isakhiwo engcono akhazimlayo emkhusaneni ngaphezu xa ukuwelda ngomoya egalelwe. Ngoko ke, oko kukhethwa kangaka liphathwa titanium. Segesi titanium indlela loo nto kwehlisa ukusebenza yenxenye.

Electron beam welding kufuneka kuneengxaki ezininzi. Kodwa ke kukho enye inzuzo ebalulekileyo, nekhuselwe ngokupheleleyo ukusuka kwindawo engaphandle sentsimbi. Oku kukuvumela ukuba umgangatho ophezulu kakhulu ngembonakalo yikristale ngekroba. Xa le nkqubo iqhutywa ngesantya esiphezulu, ukunciphisa kakhulu amandla ngobunzulu kumsebenzi owenziweyo. Kukho kwakhona i welding electro-SLAG, nto leyo ukuzokuthi ga ngoku akukabikho iye yafumana usasazo ngendlela efanelekileyo. msebenzi wayo ukuba electrode asetyenziswa ngayo umbandela ofanayo kumphezulu welding kule nkqubo.

isiphelo

Ngoku unayo ingcamango jikelele oko welding. Titanium inverter welding apho isetyenziswa ngokubanzi, uneempawu ezizodwa. Yiyo loo nto isetyenziselwe apho kungekho intsimbi efanelekileyo okanye ezinye iintsimbi. Kodwa ke iindleko eziphezulu izixhobo welding, amandla amandla inkqubo, kwakunye nezinye izinto ezininzi ezimbi ungakuvumeli kuphuhliso nokusetyenziswa kwale ngentsimbi. Noko ke, ezinye iinkampani gqolo ukuzama ukwenza kangangoko kunokwenzeka ukuze kube lula yaye kuxabise kancinane ukufumana i weld esemgangathweni. Ngokomzekelo, inkokeli kwiintengiso kwezithako yi eqinile "ELF Villingen" - "Titan". welding Cold usebenzisa inkampani uba kwaye elide. Kakade ke, lo rookie abanakukwazi ukumelana umsebenzi onjalo, kodwa ke kuya kuthi kube lula kakhulu ukuba benze umsebenzi wabo. Ngokusisiseko, oku konke elinokubaliswa malunga ukuwelda sisinyithi, ezifana titanium.
