Kev vuam yog ib txoj kev sib txuas hlau uas tseem ceeb heev rau kev tsim khoom, kev tsim kho, thiab ntau lwm yam lag luam. Hauv tsab xov xwm no, peb yuav tham txog phau ntawv qhia txog kev siv lub tshuab vuam kom zoo thiab muaj kev nyab xeeb. Peb yuav hais txog ntau hom tshuab vuam, lawv cov txheej txheem ua haujlwm, thiab cov lus qhia kev nyab xeeb kom ntseeg tau tias cov txheej txheem vuam du thiab tsis muaj kev pheej hmoo.
Hom Tshuab Vuam
Ua ntej pib txoj kev vuam, nws yog ib qho tseem ceeb kom nkag siab txog ntau hom tshuab vuam uas feem ntau siv:
1. SMAW (Shielded Metal Arc Vuam) Tshuab Vuam
- Kuj hu ua kev vuam siv pas nrig.
- Siv lub electrode uas muaj flux-coated los tsim ib lub electric arc uas yaj cov hlau puag.
2. Tshuab Vuam GMAW (Kev Vuam Hlau Siv Roj Av)
- Kuj hu ua MIG (Metal Inert Gas) vuam.
- Siv cov xov hlau electrode uas lub tshuab pub mov tas li thiab tiv thaiv los ntawm cov roj tiv thaiv.
3. TIG (Tungsten Inert Gas) Vuam Tshuab
- Siv cov electrodes tungsten uas tsis yaj thiab cov roj tiv thaiv los tiv thaiv thaj chaw vuam.
- Haum rau kev vuam precision thiab hlau nyias.
4. FCAW (Flux-Cored Arc Welding) Tshuab Vuam
- Zoo ib yam li GMAW tab sis siv cov hlau hluav taws xob flux-cored.
- Haum rau kev ua haujlwm sab nraum zoov vim tias cov kua nplaum muab kev tiv thaiv ntxiv.
5. Tshuab Vuam Plasma
- Siv cov tshuab plasma kub heev los txiav thiab vuam hlau.
- Haum rau cov haujlwm uas xav tau kev ua haujlwm siab.
Cov Kauj Ruam Ua Haujlwm ntawm Lub Tshuab Vuam

2. Kev Teeb tsa Tshuab Vuam
a. Kev Kho Tam Sim No thiab Voltage:
- Kho qhov tam sim no thiab qhov hluav taws xob ntawm lub tshuab raws li qhov tuab thiab hom hlau uas yuav tsum tau vuam.
b. Kev Xaiv Hluav Taws Xob/Hlau:
– Xaiv ib lub electrode los yog hlau vuam uas haum rau hom hlau uas yuav txuas.
c. Kev Teeb tsa Roj Tiv Thaiv:
– Yog tias siv lub tshuab vuam GMAW lossis TIG, kho qhov ntws ntawm cov pa roj tiv thaiv kom haum rau qhov ntawd kom tiv thaiv kev ua qias tuaj ntawm kev vuam.
3. Cov Txuj Ci Vuam
a. Kev Tsim Arc:
– Rau SMAW vuam, tuav lub electrode ntawm lub kaum sab xis li 15-20 degrees ntawm qhov chaw ua haujlwm kom pib lub arc.
– Rau kev vuam GMAW thiab FCAW, xyuas kom meej tias cov hlau electrode tseem nyob deb ntawm cov hlau puag.
b. Kev Siv Vuam:
- Siv tes txav kom ruaj khov thiab tswj tau kom paub tseeb tias vuam sib npaug.
- Cov txheej txheem vuam xws li "weaving" lossis "stringer bead" siv tau nyob ntawm seb xav tau daim ntawv thov.
c. Kev txias:
- Cia qhov sib txuas vuam txias ua ntej ua qhov kev tshuaj xyuas ntxiv.
4. Kev Tshuaj Xyuas Qhov Tshwm Sim Vuam
a. Pom kev:
- Kev tshuaj xyuas pom yog thawj kauj ruam kom paub tseeb tias tsis muaj qhov tsis zoo xws li kab nrib pleb, qhov hws, lossis qhov hauv qhov vuam.
b. Kev Ntsuas Tsis Ua Rau Puas Tsuaj:
- Cov txheej txheem xws li kev sim ultrasonic, radiographic, lossis magnetic particle tuaj yeem siv los xyuas kom meej tias qhov sib koom ua ke ntawm qhov sib koom ua ke yam tsis ua rau nws puas tsuaj.
Kev Nyab Xeeb hauv Kev Vuam
Kev vuam yog ib qho txheej txheem muaj kev pheej hmoo siab yog tias tsis ua kom raug. Nov yog qee cov lus qhia kev nyab xeeb uas yuav tsum ua raws li:
1. Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE):
