2. Cov txheej txheem vuam ntau

TIG Welding (Tungsten Inert Gas)

    TIG welding yog ib txoj hauv kev siv ntau tshaj plaws rau kev sib txuas cov lus qhia tungsten carbide vim nws qhov tseeb thiab kev tswj xyuas cov cua sov. Nyob rau hauv cov txheej txheem no, ib tug tsis-consumable tungsten electrode generates ib tug arc uas melts lub hauv paus cov ntaub ntawv thiab cov muab tub lim hlau, uas feem ntau yog ib tug nickel-raws li alloy. Inert gas shield tiv thaiv lub pas dej ua ke los ntawm kev sib kis.

Qhov zoo:

High Precision:TIG welding tso cai rau kev tswj xyuas zoo ntawm cov vuam tsis zoo, ua rau nws tsim nyog rau cov qauv tsim thiab cov ntaub ntawv nyias.

Txo Thaum tshav kub kub cuam tshuam cheeb tsam (HAZ):Qhov no minimizes thermal distortion, khaws cia hardness ntawm tungsten carbide.

MIG Vuam (Metal Inert Gas)

    MIG vuam siv cov hlau txuas txuas ntxiv raws li cov khoom siv hluav taws xob thiab siv cov roj inert rau kev tiv thaiv. Thaum feem ntau nrawm dua TIG vuam, MIG vuam tuaj yeem ua kom paub ntau dua cov cua sov rau hauv qhov chaw ua haujlwm, uas tej zaum yuav tsis zoo rau kev siv tungsten carbide.

Qhov zoo:

Ceev:MIG vuam yog tsim rau high-volume ntau lawm vim nws ceev vuam ceev.

Versatility:Nws tuaj yeem siv rau ntau yam ntaub ntawv thiab thicknesses.

Laser Vuam

Laser vuam tau muaj koob meej nyob rau hauv kev lag luam hardmetal rau nws lub peev xwm los tsim cov welds zoo nrog tsawg thermal cuam tshuam. Cov txheej txheem no siv lub teeb laser tsom rau yaj cov ntaub ntawv hauv paus, tsim kom muaj kev sib raug zoo nrog HAZ nqaim heev.

Qhov zoo:

Precision:Laser vuam tso cai rau kev tswj kom meej thiab tso ntawm qhov vuam, uas yog qhov tseem ceeb rau txoj kev geometries.

Tsawg Distortion:Cov hluav taws xob qis qis txo qis qhov kev pheej hmoo ntawm warping lossis degrading cov carbide cov khoom.

Brazing

Brazing, thaum tsis yog ib txoj kev vuam tsoos, koom nrog cov lus qhia tungsten carbide rau cov hniav hlau siv cov hlau muab tub lim uas melts ntawm qhov kub qis dua cov ntaub ntawv hauv paus. Txoj kev no yog qhov tshwj xeeb tshaj yog thaum ua haujlwm nrog cov khoom sib txawv lossis thaum tsis txhob muaj cua sov ntau yog qhov tseem ceeb.

Qhov zoo:

Qhov kub thiab txias:Qhov qis melting point ntawm cov hlau muab tub lim pab khaws cov khoom ntawm tungsten carbide.

Dissimilar Material Compatibility:Brazing yog zoo rau kev koom nrog cov ntaub ntawv nrog txawv thermal expansion yam ntxwv.

3. Kev txiav txim siab rau qhov zoo tshaj plaws vuam

Kev npaj Pre-Weld

Kev npaj nto zoo yog qhov tseem ceeb rau kev ua tiav cov welds muaj zog. Ob lub tswv yim tungsten carbide thiab substrate yuav tsum huv si thiab tsis muaj kab mob. Cov txheej txheem xws li abrasive blasting lossis tshuaj ntxuav tuaj yeem ua kom pom qhov chaw zoo.

Kev Tswj Kub Kub

Kev tswj cov khoom siv hluav taws xob yog qhov tseem ceeb los tiv thaiv thermal puas rau tungsten carbide. Cov cua kub ntau dhau tuaj yeem ua rau carbide coarsening, cuam tshuam rau nws cov khoom siv kho tshuab. Kev siv cov txheej txheem xws li pulse welding tuaj yeem pab txo cov teeb meem kub.

Kev kho mob tom qab Weld

Kev kho cua sov tom qab vuam, xws li tempering lossis kev ntxhov siab, tuaj yeem txhim kho cov khoom siv ntawm cov welded sib koom ua ke, kom ntseeg tau tias kev ua haujlwm zoo dua hauv kev ua haujlwm siab.

4. Zoo Control

Ua raws li kev tswj hwm kev ntsuas nruj yog qhov tseem ceeb rau kev ua kom ntseeg tau ntawm cov lus qhia welded tungsten carbide. Kev kuaj tsis muaj kev puas tsuaj (NDT) txoj hauv kev, xws li kev kuaj ultrasonic lossis tshuaj ntsuam xyuas qhov tob tob, tuaj yeem pab txheeb xyuas qhov tsis xws luag ua ntej cov cuab yeej muab tso rau hauv kev pabcuam.

Xaus

Kev xaiv ntawm txoj kev vuam plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm tungsten carbide pom cov lus qhia. Los ntawm kev xaiv cov tswv yim tsim nyog, tswj cov khoom siv hluav taws xob, thiab tswj xyuas kev tswj xyuas kom zoo, cov tuam ntxhab tuaj yeem txhim kho cov kav ntev thiab kev ua haujlwm ntawm cov cuab yeej txiav. Raws li kev lag luam hardmetal txuas ntxiv mus, kev nce qib hauv vuam tshuab yuav ntxiv dag zog thiab kev siv cov cuab yeej tungsten carbide, ua kom lawv qhov tseem ceeb hauv kev tsim khoom niaj hnub no.
