Welding ea titanium

1. Metallic thepa le tjheseletsa parameters ea titanium

Titanium e na le matla a khoheli a manyane a ikhethileng (khoheli e khethehileng ke 4.5), matla a phahameng, e hanyetsana hantle le mocheso o phahameng le o tlase, le khanyetso e ntle ea mapetso le ho hanyetsa ho bola ha chlorine e metsi. Thepa ea mochini le welding ea titanium e amana le bohloeki ba thepa ea titanium. Bohloeki bo phahameng, ts'ebetso e betere. Ho theola bohloeki, ho fokotseha ho hoholo ha polasetiki le ho tiea, 'me ho mpefala ha ts'ebetso ea welding. Titanium e sebetsa haholo ho feta 300°C mme e monya hydrogen, oxygen le liathomo tsa naetrojene habonolo ha mocheso o le holimo, e etsa hore thepa e robehe. Titanium e qala ho monya haedrojene mochesong o phahameng oa 300°C, oksijene ho 600°C, le nitrogen ho 700°C.

Mechini ea welding ea Argon arc e lokela ho ba le ho khantšoa ha li-arc tse phahameng haholo, ho fokotsoa hona joale, ts'ireletso ea ho lieha ha khase, le lithapo tsa ho tjheseletsa lisebelisoa tsa pulse li hloka thepa ea mochini e lekanang le thepa ea motsoali.
Thepa ea sekoahelo se sireletsang e lokela ho ba tšepe e pherese kapa titanium, 'me sebopeho se lokela ho ba se loketseng ho sireletsa weld ho thibela weld ho fetola' mala. Mesh ea tšepe e sa hloekang e lokela ho kenngoa ka har'a sekoahelo se sireletsang ho bapala karolo ea ho thibela khase.

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)

2. Theknoloji ea ts'ebetso ea welding ea Titanium

Ho hloekisa pele ho tjheseletsa:
Lintho tse entsoeng ka grooved ka mochine oa angle rolling, 'me sekala sa oxide, grease, burrs, lerōle, joalo-joalo ka hare ho 25mm ka mahlakoreng ka bobeli a belisoa ka borashe ba terata, ebe o hlakoloa ka acetone kapa ethanol.

Tšireletso ea welding:

Pele ho welding, o tlameha ho qala ka ho ithuta ts'ireletso ea argon. Ha a sireletsa, motho a le mong o tšoara sekoahelo se sireletsang ho sireletsa lehlakore le ka holimo, 'me motho e mong o tšoara sekoahelo se sireletsang ho sireletsa lehlakore le ka tlaase. Mosireletsi o tlameha ho sebelisana hantle le setšepe. Ka mor'a ho cheselletsa, sekoahelo se sireletsang se ka lokolloa feela ka mor'a hore weld e pholile. Bakeng sa welding e le 'ngoe le ho etsoa ka mahlakoreng a mabeli, tlhokomelo e khethehileng e lokela ho lefshoa ho sireletsa lehlakoreng le ka morao. Haeba e sa sirelelitsoe hantle, mokelikeli oa welding o ke ke oa phalla, 'me ho ke ke ha e-ba le sebopeho.
Ha tjheseletsa e lokela ho ba le sekgeo se lekaneng sa 3-5mm ho etsa sekoti sa arc. Tšoara sethunya sa welding ka letsohong la hao le letona 'me u leke ho theola electrode ea tungsten ea sethunya sa welding. Tšoara terata ka letsohong la hao le letšehali 'me u sebelise monoana o motona le oa bohareng ho tiisa terata ea welding ebe u e romela pele. Ha u romela terata ea welding, u lokela ho boloka ts'ebetso le botsitso. Matsoho a mabeli a lokela ho sebelisana hantle ho boloka weld e bataletse. Mahlo a lokela ho lula a shebile botebo ba letamo le entsoeng ka ho qhibilihisoa le ho phalla ha mokelikeli oa welding. Ea hona joale e lokela ho fetoloa ho ea ka melao ea tsamaiso 'me hona joale e feteletseng e thibetsoe.

Nozzle argon gase e bolokoa ho 5ml, khase e sireletsang e bolokoa ho 25ml, 'me mokokotlo o bolokoa ho 20ml ho netefatsa hore weld ha e fetole mmala ka mor'a sekoahelo se sireletsang. Ha ho tjheseletsa habedi, nako e itseng ya ho phodisa e lokela ho tlohelwa ho fokotsa mocheso o kahodimo ho 200℃, ho seng jwalo mapetso le brittleness di tla hlaha habonolo. Ho tjheseletsa sephara le ho tjheseletsa nozzle ho lokela ho sebediswa ka hohle kamoo ho ka kgonehang.

Ha ho cheselletsa, kamore e lokela ho ba e omileng le e se nang lerōle, lebelo la moea le lokela ho ba tlase ho 2 metres / motsotsoana, 'me meea e matla e ka baka ho se tsitse ha arc habonolo. Ha u kenya welding, leka ho sebelisa sesebelisoa sa pulse ho etsa hore weld e be ntle.
