Welding Electroslag: uhlobo kunye nohlobo

imisebenzi welding kunye nesinyithi kaninzi ngokusekelwe kwiinkqubo ephuphumayo yokunyibilikisa kwemichiza-thermal. Kuxhomekeka phezu tooling esetyenzisiweyo, ezisetyenziswa ziphele esebenzayo kunye nombutho zobugcisa ngokubanzi neemeko inkqubo, kwaye ukutshintsha iimpawu imveliso onesiphumo. Umsebenzi ophambili we-zentsimbi kukuba ukwenza joint ixesha elide into enokumelana imithwalo leyo iza kuwa phezu kwisakhiwo esikhulu. Kule nkalo, welding electroslag ayikho simse ezikhoyo namhlanje ibe sesichengeni classical arc yombane kuvumela ukuyilwa evumayo ngakumbi ukusebenza ngakumbi beentanda. Nangona kunjalo, ukusetyenziswa zeBlack webhate ukunyibilika msebenzi ubonelela ezinye izibonelelo ezininzi apho iinkampani ezinkulu ukusebenzisa obu bugcisa.

ISISHWANKATHELO electroslag welding

Indlela electroslag welding ngokusekelwe isicelo ubushushu nto leyo eyenziwe ngexesha izinto anyibilike. Oku kubangela amandla thermal yaye ngaloo ndlela wenza into enika umsebenzi welding. Njengokuba material leyo exonxiweyo, ufakwa, zeBlack kusetyenziswa basis. I-arhente causative yenkqubo anyibilike yi umsinga wombane, ngoko ijanareyitha ekhethekileyo esetyenziswa kwinkqubo yentlangano. Lweempawu ezizodwa zale nkqubo ziquka inyaniso yokuba iwelding electroslag iya kwenziwa kuphela preforms ukufakwa nkqo. Phantsi yempembelelo ubushushu eyenziwe metal ulwelo, oluthi luqokelelane ngexesha iingcingo electrode reflow izinto welding, Wawuzalisa isithuba phakathi iindawo. Ukuze ugcine engamanzi zeBlack nentsimbi webhate evela ukuphuphuma ngokugqithiseleyo, kunye namaqela eyahlukileyo esebenza bath ebekwe izilayidi amanzi obandayo. Njengoko umthungo welding bayavuka ungalinikeli yokusebenza flow abaninzi.

inkqubo

Iqala i arc inkqubo excitation, nto leyo eza kuyilwa phakathi kwezahlulo kunye iingcingo electrode. Amandla emhlabeni le arc linyibilike wobhobhozayo, uze kukwadala zeBlack bath kanye kwinqanaba apho baya kuvuswa,. Ngenxa impahla Unikezelo lombane, ngobhobhozo edidekile uqalisa shunt i arc, ukuyeka wokutsha kwayo. Xa oku inyibilikiswa nawamaziko waqhubeka ithende ngenxa yeziphumo thermal, leyo umthombo yangoku isenzo ebebunikwe loo zeBlack engamanzi. Oko kukuthi, inkqubo electroslag welding ngokusekelwe ukutshintshwa ubushushu ukusuka SLAG, kodwa ukhupha kuphela amandla nomsinga, kodwa angathumela ngqo iinxalenye zayo zokusebenza.

I electrode kwaye ekujoliswe etyhidiweyo amaqhina oqhagamshelwano ngokusebenzisa kanye webhate zeBlack. Okulandelayo ibunjiwe webhate metal. Oku kufuna amathuba ezahlukeneyo, ngokuxhomekeke iimpawu eziphathekayo. Into ebalulekileyo kukuba isiseko engamanzi but is kumgangatho osezantsi webhate SLAG, kodwa ifuna uqhagamshelwano nkosana abatyibilikisi ubezivingcile ukuvuza. Ukulungiselela le njongo, kwizilayida zokugqibela zobhedu, zipholile ngamanzi.

ezahlukeneyo welding

Iindlela ukuphumeza le ndlela ziyahluka uhlobo electrode esetyenzisiweyo. Umzekelo, ukuba icebo classical lubandakanya ukusetyenziswa wire welding apho kondliwa njengoko kunyibilika ukuya bath zeBlack. Kule ndlela, inkosi kufuneka azise i electrode nabo Buyisela isindululo tyaba, ebonelela zokufudumeza efanayo iinxalenye welding kulo ubukhulu.

Enye indlela kubandakanya ukusetyenziswa electrode necandelo elikhulu emnqamlezweni okanye amacwecwe. Kulo mzekelo, i electrode neyendlu inkoliso isithuba akhiwa umsantsa phakathi workpieces. iipleyiti Ukusebenzisa anda. Kwimeko enjalo iwelding scheme electroslag lwenziwa ukulindela imbalelwano onamacala lweziqalelo esebenzayo iinkcukacha. Ngenye indlela, imilo yazo kufuneka ibe efana workpiece welding. A yandisa ipleyiti umsantsa esisigxina yaye ngokuxhomekeke kurhulumente webhate zeBlack ezinokubonelelwa kwi ndawo umsebenzi nokusebenza.

izixhobo welding

Njengoko ngokuqinisekisa eqhelekileyo yombane, kulo mzekelo, kukho izixhobo okhethekileyo. Ukuze ubone iimpawu zayo kufuneka kuqatshelwe ukuba ubuchule electroslag, ngokungafaniyo nezinye iindlela iwelding ezifanayo kufezekiswa ezixineneyo yangoku ka 0.1 A / mm ^2, apho amakhulu abantu phindwe kane ukuba indlela arc efanayo. Ukuze kuphunyezwe lo msebenzi kusetyenziswa oomatshini ohambelana criteria ezininzi. Le nqubo yokuqala kukuqinisekisa ukuba umsantsa phakathi kungqameko ezahlukeneyo ebhafini. Imeko yesibini kwezokuqala kubonakala kwinto yokuba izixhobo iwelding electroslag kufuneka sivumele ukuyilwa sasingenamthungo nkqo nge welding. Kwaye ke imeko yokugqibela ebonakalayo kukuba iwelding kufuneka lwenziwe indlela enye. Njengoko izixhobo ezongezelelweyo sele inikezelwe ucingo izileyi ukutya, izilayidi zangoku-ukunika akabafuni kunye imivalo kunye neetyhubhu amanzi okupholisa.

welding esetyenziswa iphele

Isiseko okusebenzayo iwelding ezinjalo - ukuba uthe electrode, nto leyo ibe nemigca enqamleze ezininzi ezisisigxina. Feed ku ngokuhlamba zeBlack inikwa ngesantya esingaguqukiyo. Koko zeBlack kunye electrode nazo zingasetyenziswa akabafuni yokunyibilikisa. Kuxhomekeka iimfuno ukufumana iziphumo, umqhubi uyakwazi ukulawula njengamanzi ukuba le nkqubo iza kwenziwa ezishiyanayo ayifani - ukulungiswa ukuze zisetyenziswe kunye electrode efanayo ukuphucula Ubushushu kwakhona kwenziwa malunga nohlobo ngentsimbi. Ngokubanzi, ngokwembono ubunzima kwinkosi, kunzima ngakumbi inkqubo electroslag ukuwelda kunye umgaqo exposure qha. Ngokuqhelekileyo, zeBlack-contact yokuzoba isicelo kwiimeko xa kuyimfuneko weld imivalo ziye kumphezulu Planar.

ubuhle be ubuchwepheshe

Enye inzuzo enkulu indlela kukukwazi weld ngaphandle kwesidingo ngenxa yokuzahlula lwangaphambili emiphethweni, ngokuba le nkqubo waqonda bubukho umsantsa phakathi iindawo zokusebenza cm ukuya ku-3. Electroslag Kwakhona ukuwelda kukho inani eliphezulu welding, nto leyo ebangela kunye nezibonelelo zemali eyongiwa kwintlangano lomcimbi. Iinzuzo ziya waziva emva kokugqitywa msebenzi. Isibakala sokuba olu hlobo iwelding Lilungiselelo macala kwisalamane edibeneyo esqwini. Lo mba ithintela ukuyilwa deformation emboxo, nto leyo ekugqibeleni lula ufakelo amalungu kunye hlengiso zabo.

Fields of application

Amathuba usebenzisa le ndlela uchazwa ixesha kunye amaphutha ayo. Le ndlela akunakwenzeka ukuba ukusebenzisa kwiintlobo ezininzi iwelding. Amaninzi, iteknoloji libandakanyeka ulwakhiwo kunye nezicelo zoshishino. Umzekelo, ukuveliswa yesakhelo enkulu, ukufakelwa kwezixhobo turbine, ukufakelwa namagubu zamafu-esibiyelweyo kunye neeyunithi kwibhoyila - oku nje inxalenye kwimisebenzi eqhelekileyo i welding electro-SLAG lisetyenziswa kuyo. Ukusetyenziswa kwale ndlela kwi imveliso ivumela ukuba bahlanganisane izakhiwo ezinkulu. Umahluko omkhulu phakathi ubuchule electroslag kwezinye iindlela ulwazi elements ebuntsimbi kukuba ukuvumela ithuba lokuthath'indawo lwenkohliso okanye iindawo alahle welding isasetyenziswa ezinkulu, ezenziwe castings amancinci okanye forgings.

isiphelo

Ngenxa yezizathu ezininzi, nkqu kwiindawo ekujoliswe kuzo obu bugcisa akusoloko kuvunyelwa ukusetyenziswa kwayo. Izithintelo zinxulunyaniswa kakhulu iintsilelo lobuchwepheshe ukuba usebenzise indlela usebenze. Umzekelo, electro-SLAG iwelding iya ingaphumeleli ukuba sihlelwe ukusebenzisa kwisiza, apho kukho kananjalo ngokukhawuleza izinto ntshikilelo thermal. Oko kukuthi, ngenxa yezizathu zoqoqosho kunye nomgangatho lojongano bugcisa lilungisa, kodwa kukho omnye ezincinane. Loo zone welding ebonakala impembelelo aphezulu thermal, ngokulandelelana, kwilungiselelo emileyo lwezinto zonke izinto ezinxulumene nabo athotyelwe phantsi yeziphumo enamandla thermal.
