Tig-tjheseletsa: makgetheng kopo

Argon tjheseletsa tig (T ungsten Ke nert G ka ), kapa batho bao e seng consumable eleketrode tjheseletsa - ha khantsitsoe selikalikoe pakeng eleketrode tungsten le likarolo welded. Kahoo, ka lekhalo segopo le hlaha entsoeng ka ho qhibilihisoa tšepe phetiso. Sena ntsetso-peleng se tukang sa arcing le haholo eketsa botsitso lona. Ho feta moo, tig-tjheseletsa ho fokotsa e le mouoane tahlehelo, beheletse ka thoko thepa khoneha fafatse le thibela khase eo ho tswa ho tshusumetso ya lenaneng la selikalikoe ka tšepe e qhibilihisitsoeng. Ka lebaka leo, ho cheseletsa boleng o tsosoa ho le lecha, boemo ba tsoetseng pele ho feta.

Tig-tjheseletsa e le lenaihana kapa DC, 'me, ha ba e qetellang e sebediswa feela ho toba polarity, ke hore, ha seemelong "garena" polaka welded likarolo, le ho bolaeang "e ho tloswa" - bao e seng consumable eleketrode. Ho hlokahala hore a amahanya ka tsela ena ka lebaka la ha e le hantle hore haeba fapanyetsana bolaeang, le kgonego ya overheating bonahalang tungsten refractory tšepe, 'me ka lebaka leo ho hanyetsa lona marotholi haholo. Ho phaella moo, e ka 'na ea bakela chipping kapa qhibiliha tsa eleketrode e, ho fellang ka ke keng ea qojoa ka likoli tsa ao cheseletse ena.

Tig tjheseletsa bolela latelang likarolo tse khōlō dimela moralo: ba mohloli oa lenaihana kapa DC, selikalikoe stabilizer, e oscillator, mochine o hona joale palo fetola, jwale pulse length jenereithara, ka khase belofo solenoid, le sesebelisoa sa ho hatella dikarolo jwale.

Tig-tjheseletsa ke bokahohleng mofuta fetisisa tsa tšepe komponeng, kaha e lumella ho ao cheseletse thepa a fapaneng ka maemo a leha e le efe sebaka.

Phahameng tjheseletsa likarolo thulaganyou e e finyelloa ka 'nete ea hore e sebelisitse matla a ho honyenyane le nako e eketsehileng ho feta mofuta leha e le ofe ea tjheseletsa. Tabeng ena, tig-tjheseletsa e sebediswa feela ha boleng litšobotsi tsa ba fumana ao cheseletse ke tsa bohlokoa tsa makhaola-khang.

The tšobotsi khethollang ena mofuta oa tjheseletsa ke 'nete ea hore argon bo hloekileng e sebediswa ho hokela ho feletseng thepa efe kapa efe, ha ka mefuta e setseng ea khase ho tjheseletsa lokela ho a khetha ka ho ya ka tšepe e welded.

Tig-tjheseletsa ke ena e rarahaneng le boima tshebetso. Ka hona, le bakeng sa seboka se hlokahalang ke welder lekaneng koetlisitsoeng. Tsela ea theknoloji e tla hloka ho eena dexterity e lekaneng, ho tloha lehlakoreng le leng ho hlokahala hore ho fana ka phepelo e lekaneng le e nakong ea lintho tse bonahalang filler, ha ka lehlakoreng le leng e tla ba serumula ho tjheseletsa.

Ha a khetha tjheseletsa mochine oa mofuta ona lokela ho ho tataisoa ke nahanelwa e latelang:

1. Ho ke ke ho hlokahala ho fumana hore na phepelo matla bokgoni ba mochine tjheseletsa.

2. Ananela ho rarahana le palo ya mosebetsi.

3. Nahanela mofuta oa tshebediso ya jwale: DC kapa lenaihana.

Ho lokela ho boela ho be le a hlokomela hore ba bang ba welders ka sebelisoa hang-hang le ka ho sa feleng le ho fapanyetsana jwale. Sena ke ho hlokahala hore ho tjheseletsa ea thepa e sa tšoaneng, tse kang aluminium le tšepe. Welders na e mengata e fapaneng makgabane jwale ho tloha 3 ho ea ho tse 500 A.
