"Welding Cold" ze-aluminiyam: irhafu, izigxeko-ncomo isicelo

Aluminium - metal elula, esetyenziswa kwishishini eminyaka. Ngeli xesha, kwaye kwafunyaniswa ukuba welding abandayo aluminiyam kwaye aluminium zayo - ekuphela kwendlela ukudibanisa workpieces.

Yintoni i welding ezibandayo?

welding Cold - ukujoyina indlela kumacandelo wentsimbi eveliswa ngaphandle ubushushu, phantsi koxinzelelo. Ekwakheni ubuhlobo ikhutshwa phandle deformation yeplastiki kunobukhulu kunye ukungena yayo kumphezulu welding. welding Cold ifumaneka ngokubanzi aluminiyam kwaye ayifuni uqeqesho kunye nezixhobo ezintsonkothileyo. Le nkqubo lwenziwa ngqo kwigumbi kubushushu igumbi. Akudingi nayiphi imithombo ubushushu kusetyenziswa arc welding.

Yenziwe ngoobani kunye iimpawu

welding Cold, enyanisweni, iglu ukuba metal kwaye abe omnye icandelo okanye icandelo ezimbini ukwakheka, equka:

• Epoxy emahlamvini ukuba zenza isiseko ukuwelda kunye noxanduva efanayo kunye plasticity nokwakheka.
• Icandelo metal njengoko lokufaka.
• arhente ezongezelelweyo kunye nezongezelelo ukuphucula adhesion, ukumelana neemeko-bume ndlongondlongo, iimpawu ubushushu njalo njalo.

Iyahlala kuxhomekeke nokubunjwa kwayo, ukusetyenziswa ezifanelekileyo kunye nomgangatho ukulungiswa komhlaba.

Phantsi kweemeko ezifanelekileyo, esisiphambuka ude ngokuqinileyo yesondo metal, kodwa, njengoko amava lubonise, omhlophe emva ekwakheni phezu komyalelo iimethi ngaphantsi iwelding yemveli. Ngenxa kucetyiswa ukuba ukulungiswa kuphela.

Iglu "welding Cold aluminiyam" afumaneka phantse kuzo zonke Kivenkile - inani elikhulu ekwakheni amazwe kunye zasekhaya ukuvelisa lo kuqamba ezahlukeneyo enye kwenye kuphela kuyilo lwangaphandle.

Imastic ngokuqhelekileyo kuthengiswa ngokohlobo umaleko-ezimbini bar efanayo udongwe, okanye ukuba lula ofakwe kwisingxobo zezindlu.

Phambi ukusebenza welding lwencwadi isijungqe aqingqiweyo (ngokungqongqo nkqo) ukuya mali efunekayo. izinto welding emva iminwe baxovula ngokukhawuleza isicelo ukuya kwindawo oyifunayo.

Umgaqo deformation ukuwelda

imiphezulu ekwakheni eyenziwe aluminium ngenxa deformation zeplastiki.

izinto lokujikeleza ekhohlo kwi iwelding abandayo lanamathela kakhulu acofwa kunye, kwaphumela ekutshatyalalisweni umaleko engaphandle, kukho nisondelelane aphakathi, kusekwe isibopho.

Ukubonelela nenkangeleko engcono ngenxa iinkcukacha kwangaphambili, kungakuhle ukuba degrease, ukususa uthuli.

Indlela welding ebandayo

aluminium compound inkqubo ezibandayo Technology lungohlulwa lube iindlela 3:

• lempundu;
• endaweni;
• suture.

lempundu welding

Kule ndlela, lo workpiece aluminiyamu ibekwa kwaye ska kwi isiponji ekhethekileyo. Ngakubo ondliwa umkhosi leyo ngqo ecaleni esqwini. Ngenxa yoko, izinto ubuninzi ngokuqinileyo idibane, kunye deformation zeplastiki kwenzeka.

Le ndlela iye neengxaki ezininzi:

• qhagamshela inxalenye elide phantse kungenakwenzeka, ngenxa yobukhulu bawo anqongophele ngenxa kuyilo isixhobo nokubotshwa;
• inxalenye preforms ibekwe emkhonweni-nokubotshwa, kuba likhubazeke;
• kunzima ukuba simunce inxalenye eligaqa.

indawo welding

Le ndlela isetyenziswa ukuwelda workpieces aluminiyam akramnceleyo. Usebenzisa ayekelele ezizodwa. Indawo ubizwa ngokuba Punch ayicinezele ingongoma welding. amanqaku Weld zicwangciswe kumgca ukudibanisa emva kokuba lokuphumla ethile.

Abaxhamla kule ndlela kukunqongophala imfuneko entengo kuqala nxalenye ephantsi deformation metal kwi kuhlangana khona. Le welding ixhaphakileyo abandayo aluminiyam. Oku kungenziwa ngaphandle nokubotshwa okanye kumalungu ezisisigxina.

komphetho welding

Ukuze ibe oluqhubekayo komphetho welding kule ndlela zinokusetyenziswa izileyi, phakathi apho workpiece okanye ukusukelwa ayekelele thunzi.

Welding zingenziwa noba yenye mqengqeleki kwamaphiko, ndingungelwe amalungu ukuba inkxaso-aluminiyamu, okanye izileyi ezimbini ejikelezayo leyo ubambe amalungu kunye.

Kuxhomekeka neenkcukacha icandelo mqengqeleki umthungo enokwenziwa kumatshini wokugaya okanye desktop manual.

Ngale ndlela, i-compound ifunyenwe ngaphandle flanging ingenamthungo; kodwa yayo ethile - olindelwe amalungu icandelo kwi umthungo, ezikhokelela esime kunye inflection workpieces kule ngongoma.

Nciphisa abaphumeleli enjalo kuphunyezwa ngokwandisa sangqa kumphandle ukusebenza le roller. Okanye ukusetyenziswa kwale ndlela kufuneka kuphetshwe.

aluminium iwelding ubuchule

Iwelding shift - indlela ngengqele iwelding aluminiyam. indlela ucinezelo lwenziwa nge tangential offset. Ngenxa yale nkqubo, zonke bhanya oxide amaqonga off, le iibhulorho uyila udibaniso. Le ndlela isebenzayo beziko lezoshishino iingcingo kunye iingcingo netroli, kwezixhobo zerediyo housings, sheaths intambo, scaffolds kwizixhobo ezahlukeneyo. Ziziphumo ezisemagqabini lufumaneka xa ukuwelda aluminiyam evela aluminium yayo (subject ntumbuluko preforms indawo). Kwimeko kukuzuza ubulunga elungileyo zo xhulumaniso phantse akunakwenzeka encinane kakhulu ungcoliseko.

Ukuze ufumane uqhagamshelwano elungileyo, kufuneka ibe ludaka xi kungaba ukuze intsimbi ukwazi ukuhamba lula macala omabini kuloo ndawo weld. Kuphela abulawe imeko enjalo kuya kukhokelela ukubana elichanekileyo izahlulo ngokunxulumene nenye.

Omhlophe kuxwebhu aluminiyam, unga:

• ngqo;
• setyhula;
• oluqhubekayo (nayiphi na ubude).

Ukusetyenziswa kunye iimpawu

Phambi kokuba wobuso ukuba icocwe ngokusebenzisa ojikelezayo iibhrashi ngentsimbi. Welding lealuminium na kwenziwa metal ezahlukeneyo. Lidla wayedla ukuwelda kwimibhobho aluminium. Phantsi kweemeko laboratory, behluleke ukuphumeza welding ye-aluminiyam usebenzisa iyafa zentsimbi kunye.

Kuba welding kubanda kukho ikamva enkulu. Nangona yokuba ngoku ukuphuhliswa iindlela ezintsha zokusetyenziswa rhoqo ngoku ophezulu, loo izityalo bafumana imali eninzi ngokwaneleyo, yaye ukusebenza kwawo lisekwaqhuba kwinqanaba elisezantsi ngokufanelekileyo.

Ukuwelda kunye brazing iya kwenziwa phantsi kwempembelelo imisinga uqhutyelwe. Xa segesi aluminium DC uyakwazi maluqhutywe ngolu hlobo: Isisombululo kwealkali angaphantsi iintonga ezimbini ngoko iwise current rhoqo. Ngenxa kufudumala ngokukhawuleza lwenzeka intonga thabatha. Ngoku kuyimfuneko ukuba ukususa kweentonga ezo wenze uyilo.

Le ndlela lisetyenziswa neelabhoratri. indawo zolu shishino wafumana.

Xa welding ebandayo wenziwe-aluminiyam, akukho iinxalenye ukufudumeza lwangaphandle. It ikuvumela ukuba ukwazi ukuqhagamshela kwi ucingo yokugquma yombane, ukuba enze umsebenzi kwingingqi olunokutsha, ukuplaga imingxuma ezingaphakathi kwisikhongozeli, ongayi kuba shushu ngako. Ukongeza, i-aluminiyamu compound kungenzeka ngentsimbi. Xa usebenzisa welding abandayo olwandlwe lwe-metal aluminiyam nga ukunciphisa inkunkuma izihlandlo ezili-10. Ngokusebenzisa izixhobo iwelding ye-aluminiyam, ndawonye zekopolo titanium, kunye nezinye zesinyithi kunye aluminium nokuba plasticity. Kuba aluminium welding akusoloko fluxes kuyimfuneko.

Spot iwelding kuqhagamshelwa Ebubanzini sheet metal we-15 mm.

Lempundu-uncediswa iintonga kwicandelo umnqamlezo ukuya kwi-30 mm kunye locingo le ubukhulu efanayo. welding Cold ukujoyina aluminiyamu strip ekwaziyo-lobushushu eliphezulu copper-icandelo 100 x 10 mm ezi ingenamthungo ixesha elide kakhulu.

Komphetho welding phezu abaza sheet wafumana itywina hermetic ngokupheleleyo nawuphi na ubude

aluminium ebandayo indlela welding ezilungiselelwe iimeko zokubhala. Izixhobo abe nezixhobo imvula, amanzi ekuqhubeni into, izahlulo nokubotshwa nezixhobo.

Ubume welding abandayo ukusetyenziswa indlu ziquka fillers, nentlaka epoxy, sulphur additive. Xa ukwakheka Polymer unalo impahla ayibi elivela abile. It zingafumaneka ngokuthi baxovula isiqwenga umcimbi ezandleni zakhe okwemizuzu embalwa. Ngoko ke ubunzima linokusetyenziswa iinxalenye kuhlangana khona.

Ezo uhlobo iwelding kusetyenziswa xa usenza zokulungisa izixhobo ezincinane indlu, xa zishishina zisithengisela nesempilweni, risers, radiators, iifestile, zeemoto, amatanki amafutha, njalo-njalo. D.

Weight emva enganyangekiyo unako yokunyuselwa, ukuba luyasetyenzwa, nayiphi na imilo. ukuqaqadeka epheleleyo kwenzeka ngaphakathi 1-8 h. Iinkcukaca ngoko ziipeyintiwe.

welding Cold angqina aluminiyam abantu basebenzisa oko ngokuphindaphindiweyo wafumana ezihle kakhulu. Emva kokuhlalutya kubo, siyakwazi ukubona ukuba lo iyahlala nomgangatho uqhagamshelwano, njengoko umthetho, ixhomekeke ngokupheleleyo le ngcina ezikhethiweyo kunye nokuphunyezwa eyiyo ubuchwepheshe.

welding Cold ye-aluminiyam eSt Petersburg oluqhutywa iigaraji ezizodwa kunye ngokuzimeleyo ekhaya. izinto nokupakishwa uvela 38-40 engange.

Ekhethwayo i welding ebandayo aluminium

It yenzelwe ukulungisa iindibano kunye namalungu isithuthi eyenziwe-aluminiyam, silumin kunye duralumin.

I welding ebandayo fast "Polirem-Aluminium", nto leyo ifomula ephuhliswe ngokukodwa adhesion ngcono aluminiyam kwaye aluminium ayo, yenza kube lula ukuqhuba ezikumgangatho ophezulu kunye nokulungiswa enokuthenjwa iinxalenye aluminiyam ngaphandle kokusebenzisa kumatshini welding.

Ukusebenzisa le welding ezibandayo, kunokuba ngempumelelo ngokukhawuleza ukulungisa:

• ngesini aluminium;
• radiators imoto;
• Imibhobho eyenziwe aluminium okanye aluminium;
• ekhanda iimoto cylinder;
• panel zomzimba kunye nezinye iinxalenye imoto.

welding Cold ye-aluminiyam, ixabiso apho ixhomekeke iphakheji kwaye engange-40., ngokukodwa uqulathe lokufaka, ebonelela ngakumbi adhesion ukubunjwa na aluminiyam kwaye aluminium yayo.

Ngoku kufuneka ndinikhathaze ngakufuna kunye zentsimbi - nje athathe i welding abandayo-aluminiyam, mix izandla ukwakheka aze aqalise ukuyilungisa.
