Ceev tam sim no thiab weldability yog qhov tseem ceeb ntawm pob tw ntawm lub taub qab vuam tshuab uas cuam tshuam nrog kev ua tau zoo thiab kev ntseeg tau ntawm cov ntaub ntawv hauv Welds.Kab lus no muab cov ntsiab lus ntawm qhov ceev tam sim no thiab nws txoj kev sib raug zoo nrog weldability nyob rau hauv cov ntsiab lus ntawm lub taub qab vuam tshuab, qhia txog lawv qhov tseem ceeb hauv kev ua tiav cov txheej txheem vuam zoo.
- Nkag siab txog qhov ntom ntom tam sim no: Tam sim no qhov ntom ntom yog hais txog qhov concentration ntawm cov hluav taws xob tam sim no nyob rau hauv ib qho chaw tshwj xeeb ntawm qhov sib koom ua ke thaum lub sijhawm vuam.Nws yog ib qho tseem ceeb tsis zoo uas cuam tshuam ncaj qha rau qhov tob ntawm kev nkag mus, fusion, thiab kev faib hluav taws xob hauv cheeb tsam weld.
- Factors Influencing Current Density: Ob peb yam cuam tshuam rau qhov ceev tam sim no, suav nrog cov vuam tam sim no, electrode loj, cov khoom siv ua haujlwm, kev sib koom ua ke, thiab vuam ceev.Kev tswj xyuas kom zoo yog qhov tseem ceeb rau kev tswj qhov ceev tam sim no thaum vuam.
- Kev nkag mus thiab Fusion: Tam sim no qhov ntom ntom ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov tob ntawm kev nkag mus rau hauv cov khoom ua haujlwm.Qhov ceev dua tam sim no ua rau muaj kev nkag siab ntau dua, thaum qhov qis dua tam sim no yuav ua rau tsis txaus fusion.
- Thaum tshav kub kub Distribution: Tam sim no qhov ntom ntom kuj cuam tshuam rau kev faib cov cua sov hauv thaj tsam weld.Qhov ntau dua tam sim no cov tuab ua ntau cov cua sov thiab khaus heev, thaum txo qis qhov hluav taws xob muab faib tawm dav dav.Kev tswj xyuas cov cua sov kom zoo yog qhov tseem ceeb heev kom tsis txhob overheating lossis underheating ntawm workpieces.
- Weldability: Weldability yog hais txog qhov yooj yim uas cov khoom tuaj yeem ua tiav welded.Nws encompasses yam xws li cov ntaub ntawv compatibility, kev sib koom ua ke, thiab kev tswj ntawm welding tsis, nrog rau tam sim no ceev.
- Material Compatibility: Cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm cov khoom siv hluav taws xob, uas cuam tshuam qhov kev pom zoo tam sim no xav tau rau kev ua tiav vuam.Sib piv cov vuam tsis zoo rau cov khoom siv welded yog qhov tseem ceeb rau kev ua tiav cov suab welds.
- Kev Tsim Kho thiab Kev Npaj: Kev tsim thiab kev npaj ntawm kev sib koom ua ke cuam tshuam rau weldability.Tsim kom muaj kev sib koom ua ke kom ntseeg tau tias muaj cua sov sib txawv thiab kev sib xyaw kom zoo.Kev sib koom ua ke, suav nrog chamfering thiab tu, yog qhov tseem ceeb rau kev ua tiav cov welds zoo.
- Tswjhwm ceev tam sim no: Welders yuav tsum tswj tam sim no ceev los ntawm xaiv qhov tsim nyog vuam tsis, electrode loj, thiab workpiece positioning.Qhov no ua kom ntseeg tau tias qhov ceev tam sim no ua raws li cov kev cai vuam tshwj xeeb thiab cov khoom siv.
Hauv kev xaus, qhov ceev tam sim no yog qhov tseem ceeb hauv cov tshuab vuam pob tw uas cuam tshuam ncaj qha rau qhov tob ntawm kev nkag mus, fusion, thiab cua sov faib hauv thaj tsam weld.Nkag siab txog qhov ceev tam sim no thiab nws txoj kev sib raug zoo nrog weldability yog qhov tseem ceeb rau kev ua tiav cov txheej txheem vuam zoo.Los ntawm kev tswj thiab ua kom zoo dua tam sim no los ntawm kev xaiv qhov tsis zoo, kev ntsuam xyuas cov khoom siv sib xws, thiab kev sib koom ua ke, cov welds tuaj yeem ua kom cov welds zoo, txo qhov tsis xws luag, thiab txhim kho kev ntseeg tau ntawm cov qauv welded.Kev hais txog qhov tseem ceeb ntawm qhov ceev tam sim no thiab nws lub luag haujlwm hauv weldability txhawb kev nce qib hauv vuam tshuab thiab txhawb nqa kev ua tau zoo hauv kev lag luam vuam.
