High-tech argon iwelding

Isethi kweemveliso ezisetyenziswayo ekhayeni kushishino, eyenziwe isinyithi kunye aluminium zabo. Kuba ixesha elide yaye ezikumgangatho ophezulu uqhagamshelo esisigxina iimveliso metal indlela engcono - i welding nokumanyana. Phakathi ndlela, efikeleleka kakhulu, kwaye ivumela ukuba bafumane umgangatho elungileyo weld, welding argon na igama. Olu hlobo arc. Emayiphunyezwe arc evuthayo phakathi non-eziphelayo (ngokuqhelekileyo - Tungsten) electrode kunye workpiece otyhidiweyo. I electrode ifakwe kwi nesikopi nangaphandle kunikwa kwindawo yokunyibilika i kwemathiriyeli lokufaka asiyiyo inxalenye yombane. Kungqameko metal nezinto lokufaka inyibilikiswa yi plasma arc kwaye ukwenza umthungo. Ukuze weld echibini nge zisiza esatsiba kwimo oluzenzekelayo sasiyinikile irhasi egalelwe yi argon. Oku kusebenza Asingeni intsebenziswano imichiza kunye etyhidiweyo kunye neegesi kwasekwa kwindawo arc. Ngenxa yokuba u yi-38% nzima ngaphezu komoya, yehlele, kancinane iigesi emoyeni ukusuka kwindawo weld, ngaloo ndlela ukhusela kuyo nokuthintela kukuvela ziintsilelo welding. Ukunciphisa porosity weld, ukuze zongezwe argon ka-3-5% ioksijini, ngoko ukhuselo but is iyasebenza.

Argon welding inikeza ukuyilwa weld yi-inki jet okanye ukudluliselwa metal globular. yodluliselo Globular kubangela eziziintsali ngokubanzi kwaye awukwazi ukufikelela inkqubo iwelding oluzinzileyo. iimpawu kwezobugcisa inokufumaneka xa le umthungo mbi kunokuba iwelding okuzenzelekayo e-CO _2. Inkjet transfer metal ibonelela argon welding kwi ukuwelda kwemisinga phezu zonxibelelwano = 260A. Kule nkqubo i welding uba esitalini weld umgangatho uyaphuculwa. Kodwa ke isicelo kul ophezulu enjalo aphela rhoqo ingqamana iimfuno zobugcisa inkqubo (umz, ngokungafanelekanga kumo lo workpiece nenguqulo iimpawu zesinyithi exutyiweyo). Kuyacetyiswa ke ngoko ukuba usebenzise isenza izinto amandla. Oku kukuvumela ukuba ukucima jet of transfer metal sele imisinga zonxibelelwano close I = 100A.

ucinezelo xa usebenzisa non-eziphelayo electrode kuthwalwa isixhobo ezikhethekileyo - an oscillator enxulumene ngaxeshanye kunye umthombo wamandla. Xa welding argon yenzelwa phezu alternating current, emva ucinezelo le arc ivuliwe ukuba imo oscillator somfanekiso, lusidla kungena pulses arc ngokutshintsha ezichaseneyo. Oku kuqinisekisa uzinzo arc.

Ukuba isicelo sangoku rhoqo, lo cathode kunye anode kwenzeka ezimagqagala release ubushushu (malunga nama-70% - ngeli anode). Ngoko ke, yodidi, aluminiyamu titanium kunye nezinye zesinyithi kwe-aluminiyam, kusetyenziswa wokwephuka ngqo nkulu preform inyibilikiswa. Al welding yenzelwa phezu kwetafise yangoku nokuxuba, nto leyo evumela ukuba atshabalalise umboniso oxide, ngaphandle nobushushu imveliso.

Kuba segesi iindawo ezenziwe yodidi engatyiwa, aluminiyam kwaye aluminium zayo nazo zinokusetyenziswa argon-arc welding kunye eziphelayo electrode. Noko ke, ububanzi balo ayemxinwa kakhulu kunokuba kunye electrode Tungsten.

Oku kusetyenziswa zombini ncwadana kunye oluzenzekelayo argon welding. Phakathi zalo eziluncedo ziquka ukukwazi ukuvelisa ambaxa iimveliso olulingana encinane ngaphandle nezinto lokufaka weld, umsebenzi-ndlela ukufikelela ngaphezulu. Le ndlela kakhulu ukuwelda lempundu ukuma imibhobho yesinyithi. Senziwe yi weld iye zobugcisa iparameters elungileyo. Argon arc welding - ubuchwepheshe, imichiza ifanelekileyo ngenxa yodidi exutyiweyo, aluminiyamu, titanium, aluminiyam.

Ngenxa elula relative le ndlela, argon ukuwelda ngezandla zabo alukho kuphela abatyhidi abaqeqeshiweyo. Kulo mzekelo, ngenxa imali encinci emisebenzini, hayi imveliso kubaluleke kangaka eliphantsi inkqubo, nto leyo enciphisa ukusetyenziswa kwayo kwimveliso ngomlinganiselo omkhulu.
