Mokhoa oa ho Welding oa PDC

Joalokaha sehlooho sa rona sa ho qetela se bontša, ho ea ka mokhoa oa ho futhumatsa, mokhoa oa ho roala o ka aroloa ka ho chesoa ha lelakabe, vacuum brazing, vacuum diffusion bonding, high-frequency induction brazing, laser beam welding, joalo-joalo Sehloohong sena a re tsoeleng pele ka holimo 'me re tle ho brazing e phahameng ea maqhubu, le ho cheselletsa beam laser.

PDC high-frequency induction brazing

Brazing ea maqhubu a holimo e sebelisa induction ea motlakase ho fetolela matla a motlakase ho matla a mocheso ka har'a tšepe ea brazing filler le sesebelisoa sa ho sebetsa, ho futhumatsa tšepe ea brazing hore e be boemong bo qhibilihisitsoeng. PDC's high-frequency induction brazing process ke theknoloji ea bohlokoa bakeng sa ho roala lisebelisoa tsa ho itšeha tsa PDC.

Monyetla oa PDC e phahameng ea maqhubu a induction brazing:

1.    lebelo la ho futhumatsa le potlakile, le ka fokotsang tahlehelo e tukang ea lera la taemane la polycrystalline ea PDC le degree ea oxidation ea carbide e samente

2.    etsa bonnete ba ho nepahala ha likarolo

3.    hoo e batlang e se na tšilafalo ea tikoloho

4.    ho bonolo ho elelloa tlhahiso ea othomathike.

PDC laser beam welding

Laser Beam Welding e sebelisa lebone la laser le matla a phahameng joalo ka mohloli oa mocheso, ka ho laola bophara ba laser pulse, matla, matla a holimo, maqhubu a pheta-phetoang, le liparamente tse ling ho etsa hore sesebelisoa se fihle botebong bo itseng ba letamo le entsoeng ka ho qhibilihisoa, ha bokaholimo bo ntse bo e-na le matla a maholo. ha ho na mouoane o hlakileng, kahoo welding e ka etsoa.

Matla a matla a lebone la laser a ka fihla ho 10 9 W / cm 2. Ka lebaka la matla a matla a matla, likoti tse nyenyane li thehoa ka thepa ea tšepe nakong ea ts'ebetso ea welding.

Matla a laser a fetisetsoa karolong e tebileng ea mosebetsi oa matsoho ka likoti tse nyenyane, ho fokotsa ho ata ha lateral le botebo ba fusion ea thepa.

Likarolo tsa laser beam welding:

1.    botebo bo boholo ba motsoako oa thepa, lebelo le potlakileng la ho tjheseletsa, le sebaka se seholo sa welding ka nako ya yuniti

Ho sebelisa laser ho tjheseletsa PDC, lenonyeletso le tjheseditsweng le fumanweng le na le matla a phahameng, ho fihla ho 1 800 MPa, mme le ke ke la senya lera la daemane. Ke mokhoa o loketseng oa ho tjheseletsa oa PDC, o sebelisoang haholo bakeng sa ho cheselletsa ka mahare a chitja a taemane.

Patlisiso le khothaletso ea PDC e ntlafalitse haholo bokhoni ba ho seha ba likotoana tsa ho cheka le lisebelisoa mme ha e bapisoa le taemane ea tlhaho, e na le ts'ebetso e ntle ea litšenyehelo. Ha ho nahanoa ka litlhoko tsa ts'ebetso le litšenyehelo tsa PDC, ho ka khethoa ts'ebetso e nepahetseng ea welding.

Haeba o khahlehela li-cutters tsa PDC 'me u batla lintlha le lintlha tse ling, u ka ITHUTA KA HO THUSA KA mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
