U atametsa haufi le plasma arc welding

Selelekela

Plasma arc welding e bolela mokhoa oa fusion welding o sebelisang beam ea plasma arc e matla haholo e le mohloli oa mocheso oa welding. Plasma arc welding e na le litšobotsi tsa matla a tebileng, tlhahiso e phahameng, lebelo le potlakileng la ho cheselletsa, khatello e tlase le deformation, arc e tsitsitseng, 'me e loketse ho cheselletsa lipoleiti tse tšesaane le lisebelisoa tsa lebokose. E loketse ka ho khetheha bakeng sa ho tjheseletsa lisebelisoa tse fapaneng tsa refractory, tse nang le oxidized habonolo, le lisebelisoa tsa tšepe tse sa utloeng mocheso (joalo ka tungsten, molybdenum, koporo, nickel, titanium, joalo-joalo).

Khase e futhumatsoa ke arc ebe e arohana. Ha e feta ka nozzle e pholileng ka metsi ka lebelo le phahameng, e hatelloa, e eketsa matla a matla le tekanyo ea ho arohana ho etsa plasma arc. Botsitso ba eona, tlhahiso ea mocheso le mocheso li phahame ho feta tsa li-arcs tse tloaelehileng, kahoo e na le ho kenella ho hoholo le lebelo la ho cheselletsa. Khase e etsang plasma arc le khase e sireletsang e potolohileng eona ka kakaretso e sebelisa argon e hloekileng. Ho ea ka thepa ea lisebelisoa tse fapaneng tsa mosebetsi, helium, nitrogen, argon, kapa motsoako oa tse peli le tsona li sebelisoa.

Molao-motheo

Plasma arc cutting ke mokhoa o tloaelehileng oa ho itšeha bakeng sa lisebelisoa tsa tšepe le tse seng tsa tšepe. E sebelisa phallo ea moea ea plasma e nang le lebelo le phahameng, mocheso o phahameng le matla a phahameng ho futhumatsa le ho qhibilihisa thepa e lokelang ho khaoloa, 'me e sebelisa phallo ea moea ea ka hare kapa e kantle kapa phallo ea metsi ho sutumelletsa thepa e qhibilihisitsoeng ho fihlela lebone la phallo ea moea ea plasma le kenella ka har'a kgutlela ho bopa leqhetso.

Thepa ea welding ea Xinfa e na le litšobotsi tsa boleng bo holimo le theko e tlase. Ho fumana lintlha, ka kopo etela:Baetsi ba Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)

Likaroloana

1. Micro-beam plasma arc welding e ka cheselletsa foil le lipoleiti tse tšesaane.

2. E na le phello ea pinhole 'me e ka finyella welding e le' ngoe le mahlakoreng a mabeli a mahala.

3. Plasma arc e na le matla a mangata a matla, mocheso o phahameng oa arc column, le bokhoni bo matla ba ho kenella. E ka finyella 10-12mm tšepe e teteaneng ntle le beveling. E ka cheselletsa mahlakoreng ka bobeli ka nako e le 'ngoe, ka lebelo le potlakileng la ho cheselletsa, tlhahiso e phahameng, le deformation e nyane ea khatello ea maikutlo.

4. Thepa e batla e rarahane, e na le tšebeliso e phahameng ea khase, litlhoko tse thata ka lekhalo pakeng tsa kopano le bohloeki ba workpiece, 'me e loketse feela bakeng sa welding ea ka hare.

Phepelo ea motlakase

Ha ho sebelisoa welding ea plasma arc, hangata ho sebelisoa lisebelisoa tsa motlakase tse tobileng le tsa droop. Ka lebaka la litšoaneleho tse ikhethang tsa ts'ebetso tse fumanoeng ho tloha tokisetsong e khethehileng ea toche le phallo e arohaneng ea plasma le khase e sireletsang, phepelo e tloaelehileng ea matla a TIG e ka eketsoa ho plasma console, 'me tsamaiso ea plasma e entsoeng ka mokhoa o khethehileng e ka boela ea sebelisoa. Ha ho bonolo ho tsitsisa arc ea plasma ha u sebelisa sine wave AC. Ha sebaka se pakeng tsa electrode le workpiece e le telele 'me plasma e hatelloa, ho thata ho sebetsa ho plasma arc,' me ka potoloho e ntle ea halofo, electrode e chesang e tla etsa hore ntlha ea conductive e be selikalikoe, e tla kena-kenana le botsitso ba arc.

Ho ka sebelisoa motlakase o feto-fetohang oa DC. Ka ho fetola ho leka-lekana ha waveform ho fokotsa nako ea poleiti e ntle ea electrode, electrode e pholile ka ho feletseng ho boloka sebopeho sa ntlha e ts'oanelang le ho theha arc e tsitsitseng.
