Chifukwa cha kuuma kwakukulu ndi kuphulika kwa ma alloys olimba, sikophweka kuwotcherera ngati zipangizo zina.Zhuzhou Chuangrui Cemented Carbide Co., Ltd. yakukonzerani njira zowotcherera za carbide, ndikuyembekeza kuti zingakuthandizeni.
Chifukwa cha kusiyana kwakukulu kwa ntchito zakuthupi pakati pa tungsten carbide ndi carbon steel, kuwotcherera ndi kumwaza kuwotcherera akadali kotheka komanso njira zothandiza zowotcherera.Kuonjezera apo, njira zina zatsopano zowotcherera monga tungsten electrode inert gas maintenance arc welding (TIG), electron beam welding (EB-W), laser kuwotcherera (LBW), etc. zikukambidwanso ndikufufuzidwa, zomwe zingagwiritsidwe ntchito kuwotcherera simenti carbide m'tsogolo.
Brazing brazing ndi njira yachikhalidwe komanso yogwiritsidwa ntchito kwambiri ndi simenti yowotcherera ya carbide.Mu njira zowotcha za simenti ya carbide ndi zitsulo, malinga ndi njira yowotchera, pali kuyatsa kwamoto wa gasi, kuyaka kwa ng'anjo, kutsekemera kwa vacuum, brazing induction, resistance brazing ndi laser brazing luso.Mulimonsemo, chitsulo chosungunuka chachitsulo chowotcha chimakhala chochepa kusiyana ndi chitsulo choyambira ndipo chimagawidwa mu mgwirizano ndi kukopa kwa capillary.Zinthu zomwe zimalumikizidwa zimaphatikizirapo zitsulo zobowola mafuta, kupondaponda kotentha ndi kozizira, nkhungu zazitsulo za ufa, mipukutu, zida zodulira ndi zida zoyezera, zida zobowola miyala, zida zopangira matabwa, ndi zina zambiri.
Chitsulo chachitsulo ndi zinthu zodzaza zomwe zimagwiritsidwa ntchito popanga brazing, zomwe zimagwira ntchito yofunika kwambiri polumikizana ndi brazing.Ntchito ya Solder ndi imodzi mwazinthu zofunika zomwe zimatsimikizira mtundu wa brazing.
Zida zopangira moto wa gasi ndizosavuta, zimatha kutenthedwa ndikuwotchedwa ndi malawi angapo molingana ndi mawonekedwe a workpiece.Chitsulo chachitsulo chimakhala chopangidwa ndi zitsulo zokhala ndi filamentous kapena flake copper-based and silver-based brazing filler zitsulo, zomwe zimakhala zoyenera kupanga kachidutswa kakang'ono komanso kupanga batch yaying'ono, koma kusankha kwa nyali yowotcherera mpweya ndi chithandizo cha kutentha pambuyo pakuwotcha ndi zinthu zina zosatsimikizika ndizowonjezereka. , ndipo khalidwe ndi kudalirika kwa brazing ndi zazing'ono.
Zokolola za odulidwa a tungsten carbide kwa induction brazing, kukana brazing ndi brazing mu ng'anjo ndipamwamba, ndipo khalidwe ndilokhazikika, koma zipangizo ndi luso zimakhala zosokoneza, kukula ndi mawonekedwe a workpiece amafunika kukhala apamwamba, ndi vacuum brazing imatha kukwaniritsa mawonekedwe apamwamba, koma zida zake ndizokwera mtengo komanso luso lake ndizovuta
Monga mtundu watsopano wa kuwotcherera kutentha gwero, laser ali ndi makhalidwe a liwiro Kutentha Kutentha, yopapatiza kutentha anakhudzidwa zone, pambuyo kuwotcherera mapindikidwe ndi yaing'ono yotsalira nkhawa, makamaka kufooketsa embrittlement wa olowa maphatikizidwe zone, amene ali ndi ubwino wamba, zomwe zimapangitsa imagwiritsidwanso ntchito powotcherera simenti ya carbide.Chifukwa chake, posankha njira yowotcherera, iyenera kukhala yabwino kwambiri, ndipo nthawi zambiri kuwotcherera mu ng'anjo kumatha kukhutiritsa chida chowotcha.
(1)Kuwotcherera mwamwayi
Vacuum kubalalitsidwa kuwotcherera ndi HIP kubalalitsidwa kuwotcherera angagwiritsidwe ntchito kuwotcherera simenti carbide.Pakuwotcherera kwa vacuum, pali zinthu zambiri zomwe zimakhudza mtundu wa olowa, monga kapangidwe kazinthu, mtundu wa welded pamwamba, vacuum degree, data ya sangweji yapakati, komanso kutentha ndi kuzizira, koma zinthu zofunika kwambiri ndi kutentha, kupanikizika ndi nthawi.Mphamvu yometa ubweya wa weld nthawi zambiri imakhala bwino ndikuwonjezera nthawi yowotcherera, chifukwa kukulitsa nthawi yowotcherera kumatha kupangitsa kuti ma micro-bumps ambiri azitha kutha, malo okhudzidwawo amawonjezedwa, kubalalitsidwa kwa maatomu ndikokwanira. zambiri, ndipo kuchuluka kwa kuwotcherera kumatha kusintha kwambiri
(2) Tungsten inert gasi kukonza arc kuwotcherera
TIG kuwotcherera, monga njira yatsopano yolumikizira simenti ya carbide ndi chitsulo, ikadali mu nthawi yoyesera.
(3)Kuwotchera mtengo wamagetsi
Electron mtengo kuwotcherera ali ndi ubwino mkulu Kutentha mphamvu kachulukidwe, mapindikidwe yaing'ono pambuyo kuwotcherera, lalikulu kuwotcherera kuya-m'lifupi chiŵerengero, ndi lonse lonse kusintha magawo muyezo, ndipo chifukwa kuwotcherera ndondomeko kutentha ndi lalifupi kwambiri, akhoza kukhala njira yatsopano kuwotcherera. kulimbitsa carbide mwa kuwongolera kubalalika kwa zinthu kumlingo wina.
