Segesi Compound Solid

izakhiwo Metal zisetyenziswa kuzo zonke amashishini, kodwa, ngelishwa, hayi yonke imveliso nga kukhutshelwa kwi-oveni okanye uhlobo. A iindawo esele zenziwe akusoloko elula ukudibanisa okanye rivet iqhosha lemenyu. Kuba Kwiimeko ezinjalo kwaye kufuneka welding (okanye uqhagamshelwano welding) - inkqubo uxhulumaniso ekhuselekileyo iimveliso zesinyithi, esekelwe kwi-compound interatomic. Ukuhlelwa kunye neentlobo ukuwelda lukhulu, kodwa eziphambili - abathathu kubo, nto leyo ke idla kumaqela eyahlukileyo elikhulu. Le ndlela mechanical, thermal iqukwe - thermomechanical. iindawo uxhulumaniso Mechanical kwahlukile welding phantsi koxinzelelo okanye uqhushumbo, sonication, ukukhuhlana. welding thermal - indlela plasma, i arc yombane, laser, umqadi electron kunye like.

iimpawu uphawu ukuwelda kunye nokudibanisa iintsimbi thermal

Phantse wonke uhlobo iwelding ubushushu kubandakanya ukusetyenziswa ucingo okhethekileyo. Xa arc, ucingo welding iqukiwe kwi electrode, kuzo zonke ezinye iimeko, ucingo ekhoyo njengecandelo eyahlukileyo ezinikwa kwindawo welding. Yena unokuba enobubanzi ezahlukeneyo kunye eziphathekayo - ngamnye intsimbi weld kufuneka wire kwayo nazo zonke iinkcukacha ezizodwa ukwanelisa iimfuno namalungu welding.

Ukulungiswa okanye ukubuyiselwa iindawo ezindala ngexesha msebenzi yenziwe yi welding - isicelo ukuze ukwazi okanye emhlabeni ngaphandle kwe umaleko omtsha ngentsimbi. kusetyenziswa Ngokuqhelekileyo ukuze kukwazi le metal efanayo, kodwa le meko ayikho imfuneko. Ngamanye amaxesha, ingakumbi ngenjongo yokuphucula iipropati mechanical kunye iimpawu yokusebenza kwicingo welding uthathe elinye kunye ikhemikali kuqamba eyahlukileyo. Umzekelo, amazinyo ibhakethi excavator ezenziwe ngentsimbi eyomeleleyo ngakumbi umxholo carbon eliphezulu.

compound segesi: ekuphawuleni wire for iwelding

Ukumakishwa kwenza kube lula ukufumanisa ukuba uhlobo kocingo kufuneka zisetyenziswe ngendlela ethile uhlobo iwelding yomsebenzi. Le yokuqala ibonisa ubukhulu kunye neempawu leta ibhalwe uhlobo ngesinyithi (ingxubevange isuntswana). Iileta "St." lithetha "ucingo iintsimbi", ndisolulela kubo amanani - iqhezu carbon ka-0,01 protsenta.Iduschaya ngenani unobumba - ipesenti dopant kwi ngocingo. izinto Alloying kuboniswe: A - nitrogen, B - yesiqephu, V - W, T - Manganese, D - Copper K - ayibe, M - molybdenum, H - nickel, phosphorus not translate the C - Si, T - titanium, F - vanadium, X - chrome, Yu - aluminiyam. Emva koko, emi ngemfano ipesenteji lwesi sakhi kwi ngocingo. Noko ke, xa pesenti ngaphantsi kwe mnye, musa ukubeka ngokomzekeliso. Umzekelo, welding wire unxibelelwano 08G2S, apho isiqulatho carbon ka - 0.08%, malunga-2% yemanganizi ngaphantsi kwe-1% lesilicon.
