Welding Technique na PDC

Kamar yadda labarinmu na ƙarshe ya nuna, bisa ga hanyar dumama, hanyar brazing za a iya raba zuwa brazing harshen wuta, vacuum brazing, vacuum diffusion bonding, high-frequency induction brazing, Laser katako walda, da dai sauransu A cikin wannan labarin bari mu ci gaba da wannan saman mu zo. zuwa high-mita induction brazing, da Laser katako walda.

PDC high-mita induction brazing

Babban mitar shigar da brazing yana amfani da induction na lantarki don canza makamashin lantarki zuwa makamashin zafi a cikin ƙarfe mai cike da brazing da kayan aiki, dumama ƙarfen filler brazing zuwa yanayin narkakkar. Babban mitar shigar da brazing na PDC shine mabuɗin fasaha don sarrafa kayan aikin yankan PDC.

Fa'idar PDC babban mitar induction brazing:

1.    Gudun dumama yana da sauri, wanda zai iya rage ƙonawa na ɗigon lu'u-lu'u na PDC polycrystalline da ma'aunin oxidation na siminti carbide.

2.   tabbatar da daidaiton girman sassan sassan

3.   kusan babu gurbatar muhalli

4.   mai sauƙin gane samarwa ta atomatik.

PDC Laser katako waldi

Laser Beam Welding yana amfani da babban ƙarfin ƙarfin Laser katako azaman tushen zafi, ta hanyar sarrafa faɗuwar bugun jini na Laser, kuzari, ƙarfin kololuwa, mitar maimaitawa, da sauran sigogi don sa aikin aikin ya kai wani zurfin narkakken tafkin, yayin da saman yana da. ba a fili vaporization, don haka waldi za a iya za'ayi.

Ƙarfin wutar lantarki na katako na laser zai iya kaiwa 10 9 W / cm 2. Saboda girman girman ƙarfin, ƙananan ramuka suna samuwa a cikin kayan ƙarfe a lokacin aikin walda.

Ana watsa makamashin Laser zuwa zurfin ɓangaren aikin ta hanyar ƙananan ramuka, rage yaduwa na gefe da zurfin haɗuwa na kayan.

Fasalolin waldawar katako na Laser:

1.   Babban zurfin haɗin kayan, saurin walda, da babban yanki na walda kowane lokaci naúrar

2.   ɗigon walda mai zurfi da kunkuntar, ƙaramin yanki da zafi ya shafa, da nakasar walda.

Yin amfani da laser don walda PDC, haɗin haɗin da aka samu yana da ƙarfi mai ƙarfi, har zuwa 1 800 MPa, kuma ba zai lalata layin lu'u-lu'u ba. Yana da manufa PDC hanyar waldi, wanda aka fi amfani da lu'u-lu'u madauwari saw ruwan wukake waldi.

Bincike da haɓakawa na PDC sun inganta haɓakar ikon yanke kayan aikin motsa jiki da kayan aiki kuma idan aka kwatanta da lu'u-lu'u na halitta, yana da kyakkyawan aikin farashi. Yin la'akari da buƙatun aiki da farashin PDC, ana iya zaɓar tsarin walda mai dacewa.

Idan kuna sha'awar masu yankan PDC kuma kuna son ƙarin bayani da cikakkun bayanai, kuna iya tuntuɓar mu ta waya ko wasiku a hagu, ko AIKA WASkon Amurka a kasan shafin.
