Thaum siv cov txiv ntoo qhov chaw vuam tshuab, nws yog ib qho tseem ceeb uas yuav tau xyuam xim rau tej yam tseem ceeb thaum vuam txheem ceev. Kev saib xyuas kom raug rau cov kev txiav txim siab no ua kom muaj kev ncaj ncees thiab lub zog ntawm qhov sib koom ua ke. Nyob rau hauv tsab xov xwm no, peb yuav tham txog cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog thaum vuam txheej txheem ceev nrog cov txiv ntoo qhov chaw vuam tshuab.
- Kev xaiv txiv ntseej: Xaiv cov txiv ntoo tsim nyog rau kev vuam yog qhov tseem ceeb. Xyuas kom meej tias cov txiv ntseej yog tsim los ntawm cov khoom siv weldable, xws li cov pa roj carbon tsawg lossis cov hlau tsis muaj steel, kom ua tiav qhov kev txhim khu kev qha. Tsis txhob siv cov txiv ntseej ua los ntawm cov khoom uas nyuaj rau kev sib tsoo los yog ua rau tawg.
- Kev Npaj Nto: Kev npaj kom zoo yog qhov tseem ceeb rau kev ua tiav qhov muaj zog thiab ruaj khov. Ua tib zoo ntxuav qhov chaw ntawm ob lub txiv ntoo thiab cov khoom ua haujlwm kom tshem tawm cov av, roj, lossis oxide txheej. Qhov no ua kom zoo hluav taws xob conductivity thiab txhawb kev pom kev zoo thaum lub sij hawm vuam txheej txheem.
- Electrode Alignment: Kev sib raug zoo ntawm cov electrodes yog qhov tseem ceeb rau kev ua tiav cov welds zoo ib yam thiab txhim khu kev qha. Cov electrodes yuav tsum tau ua kom zoo nrog cov txiv ntseej thiab cov khoom ua haujlwm kom ntseeg tau tias txawm tias qhov kev faib tawm siab thiab kev sib cuag hluav taws xob zoo. Misalignment tuaj yeem ua rau cua sov tsis sib xws thiab tsis muaj zog welds.
- Vuam Parameters: Ua tib zoo kho cov vuam tsis raws li cov txiv ntseej tshwj xeeb thiab cov khoom siv ua haujlwm. Lub vuam tam sim no, lub sij hawm, thiab siab yuav tsum tau teem nyob rau hauv qhov kev pom zoo rau cov khoom muab. Thaum tshav kub kub los yog siab heev yuav ua rau distortion los yog puas rau lub txiv ntoo los yog workpiece, thaum tshav kub tsis txaus los yog siab yuav ua rau tsis muaj zog welds.
- Vuam Sequence: Xav txog qhov sib txuas ntawm vuam thaum ua haujlwm nrog ntau lub txiv ntoo. Nws raug nquahu kom weld txiv ntoo kom zoo ib yam thiab ua haujlwm kom muaj kev sib luag hauv cov txheej txheem vuam. Qhov no yuav pab xyuas kom meej qhov zoo sib xws ntawm txhua qhov welded ceev.
- Kev soj ntsuam tom qab Weld: Tom qab vuam, ua tib zoo tshuaj xyuas cov pob qij txha. Tshawb xyuas cov cim qhia ntawm qhov tsis xws luag xws li tawg, porosity, lossis tsis tiav fusion. Siv cov txheej txheem tshuaj xyuas kom tsim nyog, xws li kev tshuaj xyuas qhov muag lossis kev sim tsis muaj kev puas tsuaj, los xyuas qhov zoo ntawm cov welds.
- Kev Tswjhwm Zoo: Siv cov txheej txheem tswj kev ua tau zoo los saib xyuas thiab txheeb xyuas qhov zoo ntawm qhov vuam. Qhov no yuav suav nrog kev puas tsuaj los yog tsis muaj kev puas tsuaj ntawm cov qauv welds los ntsuas lawv lub zog thiab kev ncaj ncees. Khaws cov ntaub ntawv ntawm qhov ntsuas qhov vuam thiab kev tshuaj ntsuam xyuas rau yav tom ntej siv.
Thaum welding tus txheej txheem ceev nrog cov txiv ntoo qhov chaw vuam tshuab, ua tib zoo saib xyuas kom meej thiab ua raws li cov txheej txheem tsim nyog yog qhov tseem ceeb rau kev ua tiav cov welds muaj zog thiab txhim khu kev qha. Kev txiav txim siab xws li kev xaiv cov txiv ntoo, kev npaj saum npoo, kev sib txuas ntawm electrode, vuam tsis sib xws, vuam ib ntus, kev tshuaj xyuas tom qab vuam, thiab kev tswj xyuas zoo ua lub luag haujlwm tseem ceeb hauv kev ua kom cov vuam zoo. Los ntawm kev ua raws li cov lus qhia no, koj tuaj yeem txhim kho kev ncaj ncees thiab kev ua haujlwm ntawm cov pob qij txha welded, muab kev ntseeg siab rau kev ntseeg siab ntawm cov khoom sib dhos.
