1. Nkag siab txog cov hauv paus ntawm cov txheej txheem vuam yeeb nkab

Kev vuam yeeb nkab yog kev sib txuas cov yeeb nkab ua ke los ua ib lub yeeb nkab uas txuas ntxiv mus thiab tsis xau. Cov txheej txheem no yuav tsum tau nkag siab zoo txog cov txheej txheem vuam xws li TIG (tungsten inert gas), MIG (hlau inert gas) thiab kev vuam ntoo. Txhua lub tshuab muaj nws cov txiaj ntsig thiab kev txwv, thiab kev xaiv cov tshuab nyob ntawm cov yam xws li hom khoom siv, txoj kab uas hla ntawm yeeb nkab thiab qhov chaw vuam.

2. Kev npaj vuam yeeb nkab

Ua ntej pib txoj kev vuam, kev npaj kom txaus yog qhov tseem ceeb heev. Qhov no suav nrog kev ntxuav cov nplaim uas yuav tsum tau vuam, xyuas kom cov kav dej tau teeb tsa kom raug thiab xaiv cov khoom siv vuam kom raug. Tsis tas li ntawd, nws yog qhov tseem ceeb kom ua raws li cov txheej txheem kev nyab xeeb thiab xyuas kom meej tias thaj chaw ua haujlwm tsis muaj kev phom sij.

3. Xaiv cov khoom siv zoo

Kev xaiv cov khoom siv vuam ua lub luag haujlwm tseem ceeb hauv kev vam meej ntawm koj txoj haujlwm vuam yeeb nkab. Qhov no suav nrog kev xaiv lub tshuab vuam, cov electrodes vuam, cov pa roj tiv thaiv thiab lwm yam khoom siv. Nws yog ib qho tseem ceeb rau kev nqis peev rau hauv cov khoom siv zoo kom ntseeg tau tias qhov kev sib txuas ntawm cov vuam thiab tag nrho cov kav dej.

4. Siv cov kev coj ua zoo tshaj plaws

Kev ua raws li cov kev coj ua zoo tshaj plaws yog qhov tseem ceeb rau kev ua tiav qhov kev vuam yeeb nkab zoo thiab ruaj khov. Qhov no suav nrog kev tswj cov kev ntsuas vuam kom raug xws li voltage, tam sim no thiab kev mus ncig ceev kom ntseeg tau tias nkag mus thiab sib xyaw kom raug. Tsis tas li ntawd, kev npaj sib koom ua ke kom zoo, suav nrog kev npaj bevel thiab ntug, yog qhov tseem ceeb rau kev ua tiav qhov kev vuam ruaj khov thiab txhim khu kev qha.

5. Xyuas kom meej tias ua raws li cov cai

Hauv ntau yam lag luam,cov txheej txheem vuam yeeb nkabyuav tsum ua raws li cov cai thiab cov qauv tshwj xeeb kom ntseeg tau tias lub kaw lus kav dej muaj kev ncaj ncees thiab kev nyab xeeb. Qhov no suav nrog kev ua raws li cov lus qhia xws li ASME B31.3, API 1104, lossis AWS D1.1. Cov neeg vuam thiab cov neeg soj ntsuam vuam yuav tsum nkag siab zoo txog cov lus qhia no thiab xyuas kom meej tias txhua txoj kev vuam ua tau raws li cov qauv xav tau.

6. Kev tswj xyuas zoo thiab kev tshuaj xyuas

Kev tswj xyuas zoo thiab kev tshuaj xyuas yog ib feem tseem ceeb ntawm txoj haujlwm vuam yeeb nkab. Qhov no suav nrog kev ua kev tshuaj xyuas pom, kev sim tsis ua puas tsuaj (NDT) thiab kev sim ua puas tsuaj kom ntseeg tau tias qhov zoo thiab kev ncaj ncees ntawm cov vuam. Cov neeg tshuaj xyuas vuam ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas tias cov txheej txheem vuam ua raws li cov kev cai thiab cov qauv tshwj xeeb.

Hauv kev xaus lus, kev paub txog cov txheej txheem vuam yeeb nkab yuav tsum muaj kev txawj ntse, cov khoom siv kom raug, kev ua raws li cov qauv zoo tshaj plaws, thiab kev ua raws li cov qauv kev lag luam. Los ntawm kev ua raws li cov lus qhia no, cov neeg vuam tuaj yeem ua kom ntseeg tau tias cov kav dej muaj kev ntseeg siab thiab kev nyab xeeb hauv ntau yam kev siv hauv kev lag luam. Kev cob qhia tas mus li thiab kev paub txog cov kev nce qib tshiab hauv kev siv tshuab vuam kuj tseem ceeb rau kev paub txog cov txheej txheem vuam yeeb nkab thiab ua tiav qhov zoo tshaj plaws hauv daim teb.
