Tungsten carbide inserts ncig saw hniav, hu ua Tungsten Carbide Tipped (TCT) pom cov hniav, TCT pom hniav yog monolithic alloy tungsten steel saw hniav, uas feem ntau hu ua thoob ntiaj teb. Cemented carbide yog cov khoom siv tawv ua los ntawm tungsten carbide hmoov (WC) los ntawm kev kub kub sintering nrog cobalt (CO) raws li kev khi, tseem hu ua tungsten steel. Siv cov cemented carbide ua lub taub hau txiav kom welded rau lub hauv paus ntawm lub voj voog hlau hlau phaj, uas yog hu ua cemented carbide ncig saw hniav.
Cov ntaub ntawv tsim nyog rau kev ua carbide ncig saw hniav yog: 65Mn, 50Mn2V, SK5, SKS51, 75Cr1, thiab lwm yam. Welding cov ntaub ntawv feem ntau suav nrog nyiaj vuam hlau thiab nyiaj vuam daim. Qhov nruab nrab txheej ntawm cov nyiaj vuam daim yog tooj liab, thiab ob sab yog nyiaj, yog li nws hu ua" sandwich" welding daim. Nws tsuas yog ua lub luag haujlwm ntawm kev tshem tawm cov kev ntxhov siab welding thiab txo qis kev cuam tshuam. Saws rau hluav taws xob saws Cov hniav yog feem ntau welded los ntawm cov nyiaj soldering hniav. Qhov zoo ntawm carbide ncig saw hniav nyob ntawm lub hauv paus steel phaj cov khoom, cov khoom siv tawv tawv, qhov tsim nyog ntawm cov khoom siv vuam thiab qhov zoo ntawm cov txheej txheem tsim khoom.
