Tlhaloso e Khutšoanyane:

Li-electrode tsa Cerium tungsten li sebelisoa hangata bakeng sa ho cheselletsa TIG ha li ntse li sebetsa hantle lits'ebetsong tsa welding tsa AC le DC. Li tsebahala ka botsitso ba li-arc tsa tsona tse ntle, litšoaneleho tse ntle tsa ho khantša, le ts'ebetso e ts'oanang e tlase, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tse tšesaane le li-welds tse rarahaneng.

Ke 'mala ofe oa tungsten o nang le 2% Ceria?

Tungsten e kopantsoe le 2% ea ceria ho etsa motsoako oa tungsten-cerium oxide oo hangata o sebelisoang e le mokhoa o mong o sa sebeliseng mahlaseli a kotsi ho li-electrode tsa tungsten tse nang le thoriated ha ho sebelisoa li-welding.

'Mala oa tungsten o nang le 2% ceria o ka fapana empa hangata o moputsoa o bobebe kapa o mosoeu. Moriti o khethehileng o ka itšetleha ka lintlha tse kang mokhoa oa ho etsa lihlahisoa le liphahlo leha e le life tse eketsehileng kapa phekolo e sebelisoang ho thepa.

Phapang ke efe lipakeng tsa Thoriated le Ceriated tungsten?

Thoriated tungsten le cerium tungsten ka bobeli ke li-electrode tsa tungsten bakeng sa welding, empa li na le libopeho tse fapaneng le thepa:

1. Thoriated tungsten:
- Li-electrode tsa tungsten tse nang le thoriated li na le palo e nyane ea thorium oxide (hangata e ka bang 1-2%). Ho eketsoa ha bathorium ho ntlafatsa litšobotsi tsa elektrone tsa elektrode, ho etsa hore ho be bonolo ho qala le ho boloka arc ea welding.
-Thoriated tungsten e tsebahala ka matla a eona a holimo a ho jara, botsitso bo botle ba arc le bophelo bo bolelele. E sebelisoa hangata lits'ebetsong tsa welding tsa DC, haholo-holo bakeng sa lisebelisoa tsa ho tjheseletsa joalo ka tšepe ea carbon, tšepe e sa hloekang, li-alloys tsa nickel le titanium.

2. Tungsten cerium:
- Li-electrode tsa Cerium tungsten li na le cerium oxide e le motsoako oa motsoako. Mefuta e tloaelehileng ea cerium tungsten e na le 1.5-2% ea cerium oxide.
- Cerium tungsten e na le qaleho e ntle ea arc le botsitso, haholo-holo lits'ebetsong tse tlase tsa welding tsa hajoale. E loketse ho tjheseletsa ha AC le DC mme ka hona e loketse mefuta e fapaneng ea lisebelisoa le lits'ebetso tsa welding.
- Cerium tungsten e atisa ho khethoa e le sebaka se seng sa mahlaseli a kotsi ho bathorium tungsten ho rarolla mathata a ka 'nang a e-ba le likotsi tsa bophelo bo amanang le ho pepeseha ha bathorium.

Ka kakaretso, ha li-electrode tsa tungsten tsa thoriated le li-electrode tsa cerium tungsten li sebelisoa ho tjheseletsa, li na le libopeho tse fapaneng 'me li loketse lits'ebetso le maemo a fapaneng. Thoriated tungsten e tsejoa ka matla a eona a holimo a ho jara 'me hangata e sebelisoa ho DC welding, ha cerium tungsten e na le qalo e ntle ea arc le botsitso' me e loketse ho cheselletsa AC le DC.

Na 2% ea thoriated tungsten radioactive?

E, 2% ea li-electrode tsa tungsten tse thoriated li nkuoa li le radioactive hanyane ka lebaka la boteng ba thorium oxide sebopehong sa li-electrode. Thorium ke ntho ea tlhaho ea radioactive e fumanehang ka har'a li-electrode tsa tungsten tse hlahisang likaroloana tsa alpha tse tlase. Leha maemo a radioactivity a batla a le tlase, ho ntse ho le bohlokoa ho tšoara le ho lahla li-electrode tsa thoriated tungsten ho fokotsa ho pepeseha ho ka bang teng.

Ka lebaka la tlhaho ea radioactive ea bathorium, tšebeliso, ho sebetsana le ho lahla li-electrode tsa thorium tungsten li hloka tlhokomelo ea tšireletso le ea taolo. Ka lebaka leo, ho na le phetoho e lebisang ho mekhoa e meng e sa sebeliseng mahlaseli a kotsi e kang tungsten cerium, tungsten lanthanate kapa likarolo tse ling tse sa tloaelehang tsa lefats'e tse nang le li-electrode tsa tungsten, haholo-holo liindasteri moo polokeho ea basebetsi le mathata a tikoloho a leng bohlokoa haholo.
