Theknoloji e phahameng argon tjheseletsa

The sete ya dihlahiswa sebelisoa ka lapeng le ho indasteri, entseng ho tloha tšepe le lits'epe tse kopantsoeng tsa bona. Bakeng sa tsoarellang le boleng bo phahameng mabapi sa feleng lihlahisoa tšepe tsela e molemo - the logan tjheseletsa. Har'a mekhoa e, batlang e le theko le lumella ho fumana e ntle boleng cheseletsa, argon tjheseletsa ka e mong ea bitsoang. Ena ke mofuta oa tjheseletsa selikalikoe. Kenngwa tshebetsong ke selikalikoe tukang pakeng tsa batho bao e seng consumable (hangata - tungsten) eleketrode le workpiece tšepe. The eleketrode e mounted ka boapeelo le kwa fuoa sebakeng qhibiliha ea lintho tse bonahalang filler hase karolo ea potoloho ea motlakase. The metshetshe tsa tšepe e le setsi le lintho tse bonahalang filler e qhibilihile ke lero la mali segopo le theha e seam. Ho ao cheseletse letamo ka boapeelo nozzle ka mokgwa wa jarolla ka ho iketsa e fuoa le khase inert ke argon. Ho hoo e batlang e ha e kena sebelisana lik'hemik'hale le tšepe e qhibilihisitsoeng le likhase thehoa libaka le selikalikoe. Ka lebaka la 'nete ea hore Ar e 38% a boima ho feta moea, ho ea theohang, displacing likhase sepakapakeng ho tloha sebakeng cheseletsa, ka tsela eo ho sireletsa le ho e thibela ketsahalo ea kholofalo e kopanetsoeng welded. Ho fokotsa ao cheseletse porosity, ka phaella ka ho re ho argon ya 3-5% oksijene, ebe tšireletso tšepe e sebetsang.

Argon tjheseletsa fana ka sebopeho ao cheseletse ke enke jete kapa phetiso globular tšepe. Globular phetiso fella ka hasana sebediswe hohle le ka se finyella thulaganyou e ea moshoelella tjheseletsa. litšobotsi tse thekenoloji fumana ha seam ena o mobe ho feta ka semiautomatic tjheseletsa ka CO _2. Inkjet tšepe phetiso fana argon tjheseletsa ka ho tjheseletsa maqhubu holim'a puisano e ntle kamehla ke = 260A. Ka mokhoa ona e tjheseletsa fetoha tsitsitseng ao cheseletse boleng e ntlafala. Empa ho sebelisa joalo phahameng amperage hangata e tsamaisanang le ditlhoko theknoloji ya tshebetso (mohlala, sa hlokahale heats ka workpiece le fetola thepa ya tšepe alloyed). Ke ka lebaka leo ke bohlale ho sebelisa ho switjha phepelo matla. Sena se nolofalletsa hore switjha ho jete tsa tšepe phetiso se maqhubu le puisano e haufi ke = 100A.

thothetsang molelo ha u sebelisa batho bao e seng consumable eleketrode etsoa ke sesebediswa se khethehileng - e oscillator amana ka e tšoanang le Mohloli o matla. Ha argon tjheseletsa o etsoa ka fapanyetsana jwale, mora thothetsang molelo tsa selikalikoe e lithuto tsa ho mokgwa wa oscillator stabilizer, ho fepa ka linaoa le selikalikoe ka ho fetola ho polarity. Sena se etsa bonnete ba botsitso ba selikalikoe ho.

Ha e sebelisoa hona joale kamehla, ho cathode le anode le hlaha lekane mocheso ho lokolloa (ka bang 70% - ka anode le). Ka lebaka leo, steels, lits'epe tse kopantsoeng thaethaniamo le lirafshoa tse ling tse ho feta aluminium, sebelisoa ka kotloloho polarity ho e fumantsa preform e qhibilihile. Al tjheseletsa o etsoa ka fapanyetsana jwale, eo dumella hore ho timetsa oxide e filimi, ntle overheating sehlahiswa.

Bakeng sa likarolo entsoe ka glassware steels ho tjheseletsa, aluminium le lits'epe tse kopantsoeng tsa lona ka 'na boela ho sebediswa argon-selikalikoe ho tjheseletsa le eleketrode consumable. Leha ho le joalo, ho pharalla lona e tsesaane haholo ho feta ba nang le li-electrode tungsten.

E e sebediswa ka bobeli pukwanana le jarolla ka ho iketsa argon tjheseletsa. Har'a melemo ea eona e kenyeletsa le matla a ho hlahisa motsoako oa lihlahisoa tsa botenya nyenyane e se nang thepa e ao cheseletse filler, mosebetsi-tsela ho fihlela holim'a metsi. mokhoa o babatsehang bakeng sa ho tjheseletsa mofeng boemo ba liphaephe tšepe. Thehoa ke ao cheseletse na entsprechen ntle theknoloji. Argon selikalikoe tjheseletsa - theknoloji, metsoako loketse ho fetisisa bakeng sa steels alloyed, thaethaniamo lits'epe tse kopantsoeng, aluminium.

Ka lebaka la tsela e bonolo le mong ka mokhoa, argon ho tjheseletsa matsoho a ka ha se fumaneha feela bakeng sa welders litsebi. Tabeng ena, ka lebaka la ho e nyenyane ea mosebetsi, ha e le habohlokoa hakaale tlaase tlhahiso ya tshebetso, e lekanyetsang e sebelisa tlhahiso khōlō.
