I-arc welding ephantsi kwamanzi ifanelekile kwimibhobho, iinqanawa zoxinzelelo kunye neetanki, ukuveliswa kwesitimela kunye nezicelo ezinkulu zokwakha, kunye nefom ye-monofilament elula, i-double wire structure, i-tandem i-wire double structure kunye ne-multi-filament structure.
I-arc welding ephantsi kwamanzi inokunceda abasebenzisi kwizicelo ezininzi ze-welding.Ukusuka ekwandiseni imveliso, ekuphuculeni indawo yokusebenza, ukuya ekuqinisekiseni umgangatho ongaguqukiyo nokunye.Abaqulunqi besinyithi abaqwalasela utshintsho kwinkqubo ye-arc welding ephantsi kwamanzi kufuneka bacinge ukuba banokufumana inzuzo eninzi kule nkqubo.
Ulwazi olusisiseko lwe-arc welding ephantsi kwamanzi
Inkqubo ye-arc welding ephantsi kwamanzi iyimfuneko efanelekileyo kwizicelo ezinzima zoshishino ezifana nemibhobho, iinqanawa zoxinzelelo kunye namatanki, ukwakhiwa kwe-locomotive, ukwakhiwa okunzima / ukumba.Ilungele amashishini afuna imveliso ephezulu, ngakumbi xa kuziwa ekudibaniseni izinto ezityebileyo, zininzi izibonelelo ezizuzwa kwinkqubo ye-arc ye-welding ephantsi kwamanzi.
Isantya esiphezulu sokubeka kunye nesantya sokuhamba sinokuba nefuthe elibonakalayo kwimveliso yabasebenzi, ukusebenza kakuhle kunye neendleko zokuvelisa, enye yeenzuzo eziphambili zenkqubo ye-arc welding ye-arc.
Olunye uncedo lubandakanya: Ukwakheka kweekhemikhali okugqwesileyo kunye neempawu zoomatshini be-weld, ukubonakala okuncinci kwe-arc kunye nomsi we-welding ophantsi, ukuphuculwa kokuthuthuzela kwendawo yokusebenza, kunye nokumila okuhle kwe-weld kunye nomgca weenzwane.
I-arc welding ephantsi kwamanzi yindlela yokutya yocingo esebenzisa i-granular flux ukwahlula i-arc emoyeni, njengoko igama libonisa, i-arc ingcwatywe kwi-flux, oku kuthetha ukuba xa iiparameters zisetiwe, i-arc ayibonakali kunye nokuphuma kwe-arc. umaleko wokuguquguquka.Ucingo lokuwelda lutyiswa ngokuqhubekayo yitotshi ehamba ecaleni kweweld.
Ukufudumeza kwe-Arc kunyibilika icandelo locingo, inxalenye ye-flux kunye nesiseko sesinyithi, senza i-pool etyhidiweyo, edibanisayo ukuze yenze i-weld ehlanganiswe ngoluhlu lwe-welding slag.Uluhlu lwezinto ezityebileyo ze-welding yi-1/16 "-3/4", ingaba yi-100% ye-welding yokungena nge-welding enye, ukuba ubukhulu bodonga abukhawulelwanga, i-welding ye-multi-pass inokwenziwa, kwaye i-weld iqhutywe ngokufanelekileyo kwaye ekhethiweyo, kwaye i-welding wire flux indibaniselwano efanelekileyo ikhethiwe.

Ukukhethwa kwe-flux kunye ne-welding wire
Ukukhetha i-flux efanelekileyo kunye nocingo lwenkqubo ethile ye-arc welding ye-arc ibaluleke kakhulu ekufezekiseni iziphumo ezilungileyo ngokusebenzisa inkqubo.Ngelixa iinkqubo ze-arc welding eziphantsi kwamanzi zodwa zisebenza kakuhle, imveliso kunye nokusebenza kakuhle kunokunyuswa ngokusekwe kwi-welding wire kunye ne-flux esetyenzisiweyo.
I-flux ayikhuseli kuphela i-weld pool, kodwa igalelo ekuphuculeni iimpawu zomatshini kunye nemveliso ye-weld.Ukuqulunqwa kwee-fluxes kunempembelelo enkulu kule miba, echaphazela ukuthwala kwangoku kunye nokukhululwa kwe-slag.
Umthamo wangoku wokuthwala uthetha ukuba obona buchule buphezulu bokubekwa kunye neprofayile yeweld ekumgangatho ophezulu inokufumaneka.
Ukukhutshwa kwe-slag kwi-flux ethile kuchaphazela ukhetho lwe-flux kuba ezinye ii-fluxes zifanelekile ngakumbi kuyilo oluthile lwe-solder kunabanye.
Izinketho zokukhetha i-Flux ye-arc soldering ephantsi kwamanzi ibandakanya iintlobo ezisebenzayo kunye nezingathathi hlangothi ze-welds.Umahluko osisiseko kukuba i-flux esebenzayo itshintsha i-chemistry ye-weld, ngelixa i-neutral flux ayifuni.
I-fluxes esebenzayo ibonakaliswe ngokubandakanywa kwe-silicon kunye ne-manganese.Ezi zinto zinceda ukugcina amandla okuqina e-weld kwigalelo lobushushu obuphezulu, ukunceda ukugcina i-weld igudile kwaye igudileyo kwizantya eziphezulu zokuhamba kunye nokubonelela ngokukhululwa kwe-slag elungileyo.Ngokubanzi, ii-fluxes ezisebenzayo zinokunceda ukunciphisa umngcipheko womgangatho ophantsi we-solder, kunye nokucoca emva kwe-weld kunye nokusebenza kwakhona.Gcina ukhumbula, nangona kunjalo, ukuba ii-fluxes ezisebenzayo zihlala zifaneleka kakhulu kwi-soldering enye okanye kabini.
Ii-fluxes ezingathathi hlangothi zingcono kwii-solders ezinkulu ze-multipass kuba zinceda ukuphepha ukubunjwa kwe-brittle, i-weld-sensitive welds.
Kukho iintlobo ezininzi zokhetho lwe-welding ye-welding malunga ne-arc welding ephantsi kwamanzi, nganye inenzuzo kunye nokungalunganga.Ezinye iingcingo zenzelwe i-welding kumagalelo aphezulu obushushu, ngelixa ezinye ziyilelwe ngokukodwa ukuba zibe ne-alloys ezinceda ukucoca ukwenza i-welding.
Qaphela ukuba iipropati zeekhemikhali kunye nokusebenzisana kwegalelo lobushushu kwi-welding wire ichaphazela i-mechanical properties of the weld.Imveliso inokunyuswa kakhulu ngokukhethwa kwentsimbi yokuzalisa.
Umzekelo, ukusebenzisa ucingo olungundoqo lwentsimbi kunye nenkqubo ye-arc ye-welding ephantsi kwamanzi kunokunyusa ukusebenza kakuhle kwe-deposition nge-15% ukuya kwi-30% xa kuthelekiswa nokusebenzisa ucingo oluqinileyo, ngelixa ibonelela ngeprofayili yokungena ebanzi kunye nengekho nzulu.
Ngenxa yesantya esiphezulu sokuhamba, iingcingo ezingundoqo zentsimbi nazo zinciphisa igalelo lobushushu ukuze kuncitshiswe umngcipheko we-welding deformation kunye nokutshiswa.
Kuzo zonke iintsimbi, i-austenitic stainless steels ineyona ndawo isezantsi yesivuno.Ngoko ke, ngokweempawu zemishini, i-austenitic stainless steel ayiyona nto ibhetele kwi-valve stem, kuba ukuqinisekisa amandla athile, ububanzi be-valve stem buya kwanda.Inqaku lesivuno alinakunyuswa ngonyango lobushushu, kodwa linokunyuswa ngokubumba okubandayo.
Siyi-stockist yekhabhoni kunye nombhobho wensimbi ongenamthungo, wamkelekile nayiphi na imibuzo, siya kuyinikezela okokuqala!
