Resistance qhov chaw vuam yog ib txoj kev siv dav rau kev koom nrog ntau yam hlau, suav nrog tooj liab alloys.Cov txheej txheem no tso siab rau kev siv cov cua sov uas tsim los ntawm hluav taws xob tiv thaiv los tsim kom muaj zog, ruaj khov welds.Hauv tsab xov xwm no, peb yuav tshawb txog cov txheej txheem ntawm kev tiv thaiv qhov chaw vuam tooj liab alloys thiab sib tham txog cov kauj ruam tseem ceeb uas cuam tshuam.
Nkag siab txog kuv
1. Kev npaj khoom siv:
Ua ntej pib txheej txheem vuam, nws yog ib qho tseem ceeb los xyuas kom meej tias cov tooj liab alloy yuav tsum tau koom nrog yog huv si thiab tsis muaj kab mob.Txhua qhov chaw impurities tuaj yeem cuam tshuam qhov zoo ntawm qhov vuam.Kev ntxuav feem ntau yog ua los ntawm cov hlau txhuam los yog cov tshuaj hnyav.
2. Kev xaiv ntawm Electrodes:
Kev xaiv ntawm electrodes yog qhov tseem ceeb hauv qhov chaw vuam qhov chaw.Electrodes yuav tsum tau ua los ntawm cov khoom siv uas tuaj yeem tiv taus qhov kub thiab txias thaum lub sij hawm vuam txheej txheem.Copper electrodes feem ntau yog siv rau vuam tooj liab alloys vim lawv zoo heev conductivity thiab durability.
3. Teem Vuam Parameters:
Kev teeb tsa cov vuam tsis zoo yog qhov tseem ceeb rau kev ua tiav qhov kev vam meej.Cov parameter yuav tsum xav txog muaj xws li:
- Vuam tam sim no: Tus nqi ntawm cov hluav taws xob tam sim no siv thaum lub vuam txheej txheem.
- Lub sijhawm vuam: Lub sijhawm siv tam sim no.
- Electrode quab yuam: Lub siab siv rau lub workpieces los ntawm electrodes.
Cov txiaj ntsig tshwj xeeb rau cov ntsuas no yuav nyob ntawm qhov tuab thiab muaj pes tsawg leeg ntawm cov tooj liab alloy tau welded.
4. Vuam txheej txheem:
Thaum cov txheej txheem vuam tau teeb tsa, cov txheej txheem vuam tiag tiag tuaj yeem pib.Cov workpieces nyob nruab nrab ntawm cov electrodes, kom ntseeg tau tias muaj hluav taws xob zoo.Thaum siv cov vuam tam sim no, kev tiv thaiv ntawm cov ntsiab lus sib txuas ua kom sov, ua rau cov tooj liab yaj yaj thiab fuse ua ke.Lub zog electrode ua kom muaj kev sib cuag zoo thiab pab tsim cov vuam.
5. Txias thiab tshuaj xyuas:
Tom qab vuam, nws yog ib qho tseem ceeb uas yuav tsum tau tso cai rau lub vuam kom txias los yog siv txoj kev tswj kom txias kom tsis txhob muaj qhov tsis xws luag.Thaum txias, lub vuam yuav tsum tau kuaj xyuas kom zoo.Qhov no suav nrog kev tshuaj xyuas cov kab nrib pleb, porosity, thiab kev sib xyaw kom raug.Yog tias pom muaj qhov tsis xws luag, lub vuam yuav tsum tau kho lossis rov ua dua.
6. Kev kho tom qab Weld:
Qee zaum, kev kho tom qab vuam tej zaum yuav tsim nyog los txhim kho cov khoom siv ntawm vuam lossis txo cov kev ntxhov siab uas seem.Qhov no tuaj yeem suav nrog cov txheej txheem xws li annealing lossis kev ntxhov siab.
Hauv kev xaus, qhov chaw welding kuj yog ib txoj hauv kev zoo rau kev koom nrog cov tooj liab alloys thaum ua kom raug.Los ntawm kev ua raws li cov kauj ruam uas tau teev tseg saum toj no thiab ua tib zoo tswj cov kev ntsuas vuam, nws muaj peev xwm tsim cov welds muaj zog thiab txhim khu kev qha hauv tooj liab alloys, ua cov txheej txheem no yog ib qho cuab yeej tseem ceeb hauv ntau qhov kev lag luam uas siv tooj liab alloys.
