High-tech argon ịgbado ọkụ

The set nke ngwaahịa na-eji na n'ụlọ na na ụlọ ọrụ, mere si ọla na ha alloys. N'ihi na a inogide na-elu-edu na-adịgide adịgide njikọ metal ngwaahịa mma ụzọ - na anọ na ịgbado ọkụ. N'etiti ụzọ, dịtụ ọnụ ala ma na-enye ohere iji nweta a ezi mma Weld, argon ịgbado ọkụ nwere ike aha ya bụ. Nke a bụ ụdị nke aak ịgbado ọkụ. Emejuputa atumatu oru site aak ọkụ n'etiti ndị na-abụghị consumable (na-emekarị - tungsten) electrode na a metal workpiece. The electrode ndokwasa na a burner na externally nyere agbaze mpaghara nke dịanyā ihe onwunwe abụghị akụkụ nke eletriki circuit. The n'ọnụ nke isi metal na dịanyā ihe onwunwe na-gbazee site plasma aak na-etolite a onuete. Iji Weld ọdọ mmiri site na burner nozulu na akpaka mode na-ọnọ na inert gas bụ argon. Ọ fọrọ anaghị abanye chemical mmekọrịta wụrụ awụ metal na, haruru guzobere aak mpaghara. N'ihi na eziokwu na Ar bụ 38% arọ karịa ikuku, ọ arịdata, displacing ikuku, haruru si Weld mpaghara, si otú na-echebe ya ma na-egbochi omume nke ntụpọ na welded nkwonkwo. Iji belata Weld porosity, nwere ike kwukwara na argon nke 3-5% oxygen, mgbe ahụ, a metal nchebe bụ n'ọrụ.

Argon ịgbado ọkụ na-enye a Weld guzobere site ink ugboelu ma ọ bụ globular metal nyefe. Globular nyefe-apụta na a wider dispersion na-apụghị iru adigide ịgbado ọkụ usoro. Nkà na ụzụ e ji mara nwetara mgbe a onuete dị njọ karịa na semiautomatic ịgbado ọkụ na CO _2. Inkjet metal nyefe na-enye argon ịgbado ọkụ na ịgbado ọkụ okwukwo n'elu nkwurịta okwu m = 260A. Na usoro a na ịgbado ọkụ na-aghọ mụ Weld quality na-akakwa mma. Ma ngwa nke ndị dị otú ahụ dị elu amperage mgbe kwekọrọ na nkà na ụzụ chọrọ nke usoro (e.g., n'ụzọ gabigara ókè heats na workpiece na agbanwe na Njirimara nke alloyed ọla). Ọ bụ ya mere amamihe na-eji ịmafe ike onunu. Nke a na-enye ohere ka ịgbanwee ugboelu nke metal nyefe ama okwukwo nso nkwurịta okwu m = 100A.

mgbanye mgbe eji na-abụghị consumable electrode ebu site a pụrụ iche ngwaọrụ - ihe oscillator ejikọrọ ke ukem na ike isi iyi. Mgbe argon ịgbado ọkụ a rụrụ na nwetụ ugbu a, mgbe mgbanye nke aak na-Switched na oscillator stabilizer mode, udia n'ime aak pulses site na-agbanwe polarity. A ana achi achi nke kwụsiri ike nke aak.

Ọ bụrụ na etinyere mgbe nile ugbu a, ndị cathode na anode emee mkpumkpu okpomọkụ ntọhapụ (banyere 70% - na anode). Ya mere, steels, titanium alloys na ndị ọzọ na ọla karịa aluminum, mee ogologo polarity jirichaa preform na-gbazee. Al ịgbado ọkụ a rụrụ na ihe nwetụ ugbu a, nke na-enye ohere ibibi oxide film, na-enweghị ekpo oke ọkụ ngwaahịa.

N'ihi na ịgbado ọkụ akụkụ mere nke igwe anaghị steels, aluminum na ya alloys nwekwara ike ga-eji argon-aak ịgbado ọkụ na consumable electrode. Otú ọ dị, ya akporo bụ nke ukwu mkpafa karịa na tungsten electrodes.

Ọ na-eji ma ntuziaka na na akpaka argon ịgbado ọkụ. N'etiti ya uru na-agụnye ikike na-emepụta a compound nke ngwaahịa na nke obere ọkpụrụkpụ enweghị Weld dịanyā ihe, na-arụ ọrụ ụzọ ohere ka elu. The usoro bụ magburu onwe ya n'ihi ịgbado ọkụ butt ọnọdụ nke metal ọkpọkọ. Kpụrụ Weld nwere ezigbo nkà na ụzụ kwa. Argon aak ịgbado ọkụ - technology, ndị kasị mma ogige maka alloyed steels, titanium alloys, aluminum.

N'ihi na ikwu mfe nke usoro, argon ịgbado ọkụ aka bụghị dị naanị maka ọkachamara welders. Na nke a, n'ihi na obere ego nke na-arụ ọrụ, ọ bụghị otú ahụ dị mkpa dị ala arụpụtaghị ihe nke usoro, nke egbochi ya iji na nnukwu-ọnụ ọgụgụ mmepụta.
