Musiyano uripo pakati peTIG, MIG uye MAG welding
1. TIG welding inowanzoita torch welding inobatwa mune rumwe ruoko uye welding wire inobatwa mune imwe, iyo yakakodzera kune manual welding yediki-scale mashandiro uye kugadzirisa.
2. Kune MIG neMAG, iyo welding wire inotumirwa kubva kune welding torch kuburikidza neatomatiki waya yekudyisa michina, iyo yakakodzera kune otomatiki welding, uye zvechokwadi inogona kushandiswa nemaoko.
3. Kusiyana pakati peMIG ne MAG kunonyanya mukudzivirira gasi. Midziyo yacho yakafanana, asi iyo yekutanga inowanzo chengetedzwa neArgon, iyo inokodzera welding isina-ferrous simbi; iyo yekupedzisira inowanzosanganiswa necarbon dioxide inoshanda gasi muargon, uye inokodzera welding yakakwirira-yakasimba simbi uye yakakwirira-alloy simbi.
4. TIG neMIG iinert gas shielded welding, inowanzozivikanwa se argon arc welding. Iyo inert gasi inogona kuva argon kana helium, asi argon yakachipa, saka inowanzoshandiswa, saka inert gas arc welding inowanzonzi argon arc welding.
Kuenzanisa kweMIG welding uye TIG welding
Kuenzanisa kweMIG welding uye TIG welding MIG welding (kunyunguduka inert gas shielded welding) muChirungu: metal inert-gas welding inoshandisa melting electrode.
Iyo arc welding nzira inoshandisa iyo yakawedzera gasi seyepakati arc uye inodzivirira madonhwe esimbi, dziva rekukweshesa uye nepamusoro-tembiricha simbi munzvimbo yewelding inonzi gasi simbi inodzivirira arc welding.
Iyo inert gasi (Ar kana He) yakadzivirirwa arc welding nzira newaya yakasimba inonzi yakanyungudutswa inert gasi yakadzivirirwa welding, kana MIG welding kwenguva pfupi.
MIG welding yakafanana neTIG welding kunze kwekuti waya inoshandiswa pachinzvimbo chetungsten electrode mutochi. Saka, waya welding inonyungudutswa nearc uye inodyiswa munzvimbo yewelding. Ma roller anofambiswa nemagetsi anodyisa waya kubva ku spool kuenda kune torch sezvinodiwa pawelding, uye sosi yekupisa ndeye DC arc.
Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Asi iyo polarity yakangopesana neiyo inoshandiswa muTIG welding. Iyo yekudzivirira gasi inoshandiswa yakasiyanawo, uye 1% okisijeni inowedzerwa kune argon kuti ivandudze kugadzikana kwearc.
Kufanana neTIG welding, inogona kupinza dzinenge simbi dzese, kunyanya yakakodzera midziyo yekukwirisa yakaita sealuminium nealuminium alloys, mhangura nemhangura alloys, uye simbi isina tsvina. Iko kunenge kusisina oxidation inopisa kurasikirwa muwelding process, ingori shoma shoma yekurasikirwa evaporation, uye iyo metallurgical process iri nyore.
TIG welding (Tungsten Inert Gas Welding), inozivikanwawo seisina kunyunguduka inert gasi tungsten shielded welding. Ingave iri manual welding kana otomatiki welding ye0.5-4.0mm gobvu Stainless simbi, TIG welding ndiyo inonyanya kushandiswa nzira.
Iyo nzira yekuwedzera waya yekuzadza neTIG welding inowanzo shandiswa kutsigira welding yemidziyo yekumanikidza, nekuti kusimba kwemhepo kweTIG welding kuri nani uye kunogona kuderedza porosity ye weld seam panguva yewelding yemidziyo yekumanikidza.
Iyo inopisa sosi yeTIG welding ndeye DC arc, iyo inoshanda voltage i10-95 volts, asi iripo inogona kusvika 600 amps.
Nzira yakarurama yekubatanidza muchina welding ndeyekubatanidza workpiece kune yakanaka danda remagetsi, uye tungsten danda mumoto welding sedanda risina kunaka.
Iyo inert gasi, kazhinji argon, inodyiswa kuburikidza nemwenje kuti iite nhovo yakatenderedza arc uye pamusoro pedziva reweld.
Kuti uwedzere kupinza kwekupisa, kazhinji 5% hydrogen inowedzerwa kune argon. Zvisinei, kana welding ferritic Stainless simbi, haidrojeni haigoni kuwedzerwa argon.
Iyo gasi inoshandiswa inenge 3-8 litita paminiti.
Muchigadziro chekugadzira, kunze kwekuputira inert gasi kubva kune welding torch, zviri nani kuridza gasi rinoshandiswa kudzivirira kumashure kweweld kubva pasi peweld.
Kana zvichidikanwa, iyo weld puddle inogona kuzadzwa newaya yemhando imwechete seyayo austenitic zvinhu zviri kugadzirwa. Type 316 filler inowanzo shandiswa kana welding ferritic stainless steels.
Nekuda kwekuchengetedzwa kweargon gasi, inogona kutsaura kukuvadza kwemhepo pasimbi yakanyungudutswa, saka TIG welding inoshandiswa zvakanyanya muwelding.
Zviri nyore oxidized asiri ferrous simbi dzakadai aruminiyamu, magnesium uye alloys avo, Stainless simbi, yakakwirira-tembiricha alloys, titanium uye titanium alloys, pamwe refractory inoshanda simbi (senge molybdenum, niobium, zirconium, zvichingodaro), nepo yakajairika kabhoni. simbi, yakaderera alloy simbi, nezvimwe zvinhu, TIG welding haiwanzo shandiswa kunze kwezviitiko zvinoda yakakwirira welding mhando.
