Vim lub siab hardness thiab brittleness ntawm hard alloys, nws tsis yooj yim rau welded li lwm yam ntaub ntawv.Zhuzhou Chuangrui Cemented Carbide Co., Ltd. tau txheeb xyuas cov txheej txheem vuam ntawm cemented carbide rau koj, vam tias nws tuaj yeem pab koj.
Vim tias qhov sib txawv loj hauv kev ua haujlwm ntawm lub cev ntawm tungsten carbide thiab carbon steel, brazing thiab disperse welding tseem ua tau thiab siv tau zoo.Tsis tas li ntawd, qee qhov kev siv vuam tshiab xws li tungsten electrode inert gas txij nkawm arc vuam (TIG), electron beam welding (EB-W), laser vuam (LBW), thiab lwm yam. cemented carbide vuam yav tom ntej.
Brazing brazing yog ib txwm siv thiab dav siv cemented carbide welding txoj kev.Nyob rau hauv txoj kev brazing ntawm cemented carbide thiab hlau, raws li cov txheej txheem cua sov, muaj cov roj nplaim hluav taws xob, lub tshuab hluav taws xob, lub tshuab nqus tsev, induction brazing, tsis kam brazing thiab laser brazing kev txawj ntse.Txawm li cas los xij, lub ntsiab lus melting ntawm cov hlau brazing yog qis dua li ntawm cov hlau hauv paus thiab muab faib rau hauv kev sib koom ua ke los ntawm capillary attraction.Cov khoom sib txuas muaj xws li cov roj zoo laum khoom, kub thiab txias stamping tuag, hmoov metallurgy pwm, yob, txiav cov cuab yeej thiab ntsuas cov cuab yeej, cov cuab yeej pob zeb drilling, cov cuab yeej ua haujlwm ntoo, thiab lwm yam.
Brazing hlau yog cov khoom siv muab tub lim siv hauv kev sib tsoo, uas ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm kev sib koom tes brazing.Solder muaj nuj nqi yog ib qho tseem ceeb uas txiav txim siab qhov zoo ntawm brazing.
Cov khoom siv hluav taws xob hluav taws xob yog qhov yooj yim, nws tuaj yeem ua kom sov thiab welded nrog ntau cov nplaim taws raws li cov duab ntawm lub workpiece.Lub brazing hlau feem ntau yog ua los ntawm filamentous los yog flake tooj liab-raws li thiab nyiaj-raws li brazing muab tub lim hlau, uas yog tsim rau ib daim thiab me me batch ntau lawm, tab sis xaiv cov roj welding teeb thiab kev kho cua sov tom qab brazing thiab lwm yam khoom tsis meej yog ntau dua. , thiab qhov zoo thiab kev ntseeg siab ntawm brazing yog me me.
Cov txiaj ntsig ntawm tungsten carbide cutters rau induction brazing, tiv thaiv brazing thiab brazing nyob rau hauv lub cub tawg yog siab, thiab qhov zoo yog qhov ruaj khov, tab sis cov cuab yeej thiab cov kev txawj ntse yog ntau ntxhov, qhov ntsuas thiab cov duab ntawm lub workpiece yuav tsum siab dua, thiab lub tshuab nqus tsev brazing tuaj yeem ua tau zoo brazing zoo, tab sis cov cuab yeej siv kim thiab cov txuj ci nyuaj
Raws li ib yam tshiab ntawm vuam kub qhov chaw, laser muaj cov yam ntxwv ntawm ceev cua kub ceev, nqaim tshav kub cuam tshuam cheeb tsam, tom qab vuam deformation thiab me me residual kev nyuaj siab, tshwj xeeb tshaj yog nyob rau hauv tsis muaj zog lub embrittlement ntawm lub sib koom fusion cheeb tsam, uas muaj ntau yam zoo, uas ua rau. Nws kuj tseem siv tau rau hauv kev vuam ntawm cemented carbide.Yog li ntawd, thaum xaiv txoj kev vuam, nws yuav tsum tsim nyog, thiab feem ntau cov brazing nyob rau hauv lub cub tawg tuaj yeem ua tau raws li cov cuab yeej brazing thov.
(1) Dispersed vuam
Nqus dispersion vuam thiab HIP dispersion vuam tuaj yeem siv rau vuam ntawm cemented carbide.Nyob rau hauv lub tshuab nqus tsev dispersion vuam, muaj ntau yam cuam tshuam rau qhov zoo ntawm qhov sib koom ua ke, xws li cov khoom sib xyaw, qhov zoo ntawm qhov chaw welded, lub tshuab nqus tsev kawm ntawv, cov ntaub ntawv ntawm qhov chaw sandwich, thiab cov cua sov thiab cua txias, tab sis qhov tseem ceeb tshaj plaws yog kub, siab thiab lub sijhawm.Lub zog shear ntawm lub vuam feem ntau txhim kho nrog qhov sib ntxiv ntawm lub sijhawm vuam, vim tias qhov txuas ntxiv ntawm lub sijhawm vuam tuaj yeem ua rau feem ntau ntawm cov micro-bumps ntawm qhov chaw welded ploj, qhov chaw kov yog pom tseeb ntxiv, qhov tawg ntawm atoms ntau dua. ntau, thiab vuam tus nqi tuaj yeem txhim kho tau zoo
(2) Tungsten inert roj tu arc vuam
TIG vuam, raws li txoj kev tshiab ntawm kev sib txuas ntawm cov cemented carbide thiab hlau, nws tseem nyob rau lub sijhawm sim
(3) Electron beam vuam
Electron beam welding muaj qhov zoo ntawm lub zog cua kub ceev, me me deformation tom qab vuam, loj weld qhov tob-dav piv, thiab kev hloov dav dav ntawm cov qauv tsis zoo, thiab vim tias cov txheej txheem vuam kub tsis tshua muaj luv, nws yuav dhau los ua ib txoj hauv kev tshiab rau vuam. cemented carbide los ntawm kev tswj cov dispersion ntawm cov khoom mus rau ib qho twg.
