Udindo wa nkhungu ya graphite pakupangira matabwa

Zoumba za graphite zimagwira ntchito yofunika kwambiri pakukongoletsa, makamaka kuphatikiza zinthu zotsatirazi:

• Yokhazikika komanso yoyikidwa bwino kuti cholumikizira chikhale chokhazikika panthawi yopangira cholumikizira, zomwe zimapangitsa kuti chisasunthe kapena kupunduka, potero kuonetsetsa kuti cholumikiziracho chili cholondola komanso chapamwamba.
  Kusamutsa kutentha ndi kuwongolera kutentha Popeza graphite ili ndi kutentha kwabwino, imatha kusamutsa kutentha mwachangu komanso mofanana, zomwe zimathandiza kuwongolera kugawa kutentha panthawi yopangira brazing, kuti zinthu zopangira brazing zitha kusungunuka kwathunthu ndikudzaza weld kuti pakhale kulumikizana kwabwino.
  Kupanga mawonekedwe ndi kapangidwe kake. Ikhoza kupangidwa kukhala mawonekedwe ndi kapangidwe kake kamene kamafunikira kuti ithandize kupanga cholumikizira cholumikizira ndi mawonekedwe a cholumikizira chomwe chikukwaniritsa zofunikira.
  Mphamvu yoteteza Imapereka chitetezo china cha weldment ndipo imachepetsa kusokoneza ndi mphamvu ya chilengedwe chakunja pa ndondomeko ya brazing, monga kupewa okosijeni.

Zoumba za graphite zili ndi ubwino wambiri pa brazing:

• Kutulutsa kwabwino kwambiri kwa kutentha Kumatha kusamutsa kutentha mwachangu, kupangitsa kuti zinthu zomangira zisungunuke mofanana, kukonza magwiridwe antchito ndi mtundu wa kulumikizana. Kukana kutentha kwambiri. Kungakhalebe kokhazikika pamalo otentha kwambiri, osavuta kuwononga kapena kuwononga.
  Kukhazikika kwambiri kwa mankhwala Sikophweka kuchitapo kanthu pogwiritsa ntchito mankhwala ndi zinthu zomangira ndi kusungunula, zomwe zimaonetsetsa kuti njira yowotcherera ndi yoyera komanso yokhazikika.
  Mtengo wotsika Poyerekeza ndi zinthu zina zomwe zimapirira kutentha kwambiri, mtengo wa nkhungu za miyala ndi wotsika mtengo, zomwe zimathandiza kuchepetsa ndalama zopangira.

Ziphuphu za graphite zimakhudza kwambiri khalidwe la brazing:

• Kukhudza zotsatira za kudzaza kwa weld
  Chifaniziro choyenera cha graphite chingatsimikizire kuti zinthu zomangira zitsulo zimadzaza bwino cholumikiziracho, kupanga cholumikizira cholumikizidwa chofanana komanso cholimba, ndikuwonjezera mphamvu ndi kutseka cholumikiziracho.
  Dziwani kapangidwe kake ka chiwalocho
  Kagwiridwe ka ntchito ka kutentha ndi mawonekedwe a nkhungu zidzakhudza kufalikira kwa kutentha ndi kuchuluka kwa kuzizira panthawi yopangira brazing, motero zimakhudza kapangidwe kake ndi magwiridwe antchito a cholumikiziracho.
  Kukhudza kulondola kwa gawo la weldment
  Kulondola kwa chikombole kumagwirizana mwachindunji ndi kulondola kwa gawo la weldment. Ngati kulondola kwa chikombole sikuli kwakukulu, kungayambitse kusintha kwa gawo la weldment ndikukhudza magwiridwe ake.
