Welding Technique ya PDC

Monga momwe nkhani yathu yomaliza ikuwonetsera, molingana ndi njira yowotchera, njira yowotchera ikhoza kugawidwa kukhala moto woyaka moto, kutsekemera kwa vacuum, kutsekemera kwa vacuum diffusion, kutsekemera kwapamwamba kwambiri, kutsekemera kwa laser, ndi zina zotero. Kuwotcherera kwa laser, komanso kuwotcherera kwa laser.

PDC high-frequency induction brazing

Kutentha kwapang'onopang'ono kumagwiritsa ntchito electromagnetic induction kuti isinthe mphamvu yamagetsi kukhala mphamvu yotentha muzitsulo zodzaza ndi zitsulo, ndikutenthetsa chitsulo chosungunula kuti chikhale chosungunuka. PDC's high-frequency induction induction process ndiye ukadaulo wofunikira pakuwotcha zida za PDC.

Ubwino wa PDC high-frequency induction brazing:

1.    liwiro lotenthetsera ndi lachangu, lomwe lingachepetse kuyaka kwa PDC polycrystalline diamondi wosanjikiza ndi oxidation digiri ya simenti carbide.

2.    onetsetsani kulondola kwa magawo

3.    pafupifupi palibe kuwononga chilengedwe

4.                                                                           > 

PDC laser kuwotcherera mtengo

Laser Beam Welding imagwiritsa ntchito mtengo wapamwamba kwambiri wa laser ngati gwero la kutentha, poyang'anira makulidwe a laser pulse, mphamvu, mphamvu yapamwamba, kubwerezabwereza pafupipafupi, ndi magawo ena kuti chogwiriracho chifike pakuya kwina kwa dziwe losungunuka, pomwe pamwamba pamakhala palibe vaporization zoonekeratu, kotero kuwotcherera akhoza kuchitidwa.

Kuchulukitsitsa kwamphamvu kwa mtengo wa laser kumatha kufika 10 9 W / cm 2. Chifukwa cha kuchuluka kwamphamvu kwamphamvu, mabowo ang'onoang'ono amapangidwa muzinthu zachitsulo panthawi yowotcherera.

Mphamvu ya laser imafalikira ku gawo lakuya la chogwirira ntchito kudzera m'mabowo ang'onoang'ono, kuchepetsa kufalikira kwa lateral ndi kuya kwa maphatikizidwe azinthuzo.

Ubwino wa kuwotcherera laser mtengo:

1.    kuphatikizika kwakukulu kwa zinthu, liwiro la kuwotcherera, ndi malo akulu owotcherera pa nthawi ya unit

2.    nsonga yakuya ndi yopapatiza yowotcherera, malo ang'onoang'ono omwe amakhudzidwa ndi kutentha, komanso kuwotcherera.

Pogwiritsa ntchito laser kuwotcherera PDC, cholumikizira chowotcherera chomwe mwapeza chimakhala ndi mphamvu yayikulu, mpaka 1 800 MPa, ndipo sichingawononge gawo la diamondi. Ndi njira yabwino yowotcherera ya PDC, yomwe imagwiritsidwa ntchito kwambiri pakuwotcherera masamba a diamondi ozungulira.

Kufufuza ndi kukwezedwa kwa PDC kwasintha kwambiri luso lodula la zida ndi zida zobowola ndipo poyerekeza ndi diamondi yachilengedwe, ili ndi ntchito yabwino. Poganizira zofunikira zogwirira ntchito komanso mtengo wa PDC, njira yoyenera yowotcherera imatha kusankhidwa.
