Lub weldability ntawm cov ntaub ntawv hlau yog ib qho tseem ceeb thaum siv cable taub qab vuam tshuab rau koom nrog cov hluav taws xob cables. Kab lus no tshawb txog cov txheej txheem thiab kev txiav txim siab rau kev ntsuas qhov weldability ntawm ntau yam khoom siv hlau, ua kom muaj kev vam meej thiab txhim khu kev qha cable welds.
1. Material Compatibility:
- Qhov tseem ceeb:Kev sib raug zoo ntawm cov khoom siv cable thiab cov hlau raug welded yog qhov tseem ceeb los tiv thaiv kev sib kis thiab xyuas kom muaj kev sib txuas huv.
- Kev txiav txim siab:Txiav txim siab seb cov khoom siv cable puas haum rau cov hlau los siv rau kev vuam. Kev tsis sib haum xeeb tuaj yeem ua rau cov welds tsis zoo thiab muaj peev xwm muaj kev nyab xeeb.
2. Melting Point:
- Qhov tseem ceeb:Lub melting point ntawm cov khoom siv hlau cuam tshuam cov txheej txheem vuam.
- Kev txiav txim siab:Xyuas kom meej tias cov khoom siv hlau melting point yog nyob rau hauv ib tug ntau yam haum rau lub vuam txoj kev thiab cov cuab yeej siv. Cov ntaub ntawv uas muaj cov ntsiab lus melting ntau dhau yuav xav tau cov txheej txheem vuam tshwj xeeb.
3. conductivity:
- Qhov tseem ceeb:Hluav taws xob conductivity cuam tshuam qhov kev ua tau zoo ntawm lub zog hloov thaum lub sij hawm vuam.
- Kev txiav txim siab:Xaiv cov hlau uas muaj hluav taws xob txaus los ua kom muaj zog hloov pauv tau zoo. Tooj liab yog ib qho kev xaiv vim nws zoo heev conductivity.
4. Tshuaj muaj pes tsawg leeg:
- Qhov tseem ceeb:Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau tuaj yeem cuam tshuam rau nws cov weldability.
- Kev txiav txim siab:Yuav tsum paub txog cov ntsiab lus lossis impurities hauv cov hlau uas tuaj yeem cuam tshuam cov txheej txheem vuam. Xaiv cov ntaub ntawv nrog cov tshuaj tsim nyog rau cov ntawv thov tshwj xeeb cable vuam.
5. Heat-Afected Zone (HAZ):
- Qhov tseem ceeb:Qhov loj thiab cov khoom ntawm HAZ tuaj yeem cuam tshuam qhov kawg weld zoo.
- Kev txiav txim siab:Nkag siab li cas cov khoom siv hlau xaiv cuam tshuam rau qhov loj thiab cov khoom ntawm HAZ. Qee cov ntaub ntawv tuaj yeem ua rau HAZ loj dua lossis ntau dua, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cable.
6. Kev npaj ua ke:
- Qhov tseem ceeb:Kev npaj sib koom ua ke yog qhov tseem ceeb rau kev ua tiav cov welds zoo.
- Kev txiav txim siab:Xyuas kom meej tias cov ntaub ntawv hlau tau npaj kom raug, nrog rau kev huv, zoo-txhim kho, thiab nruj nreem sib koom ua ke. Kev sib koom ua ke tsis txaus tuaj yeem ua rau muaj qhov tsis xws luag thiab tsis muaj zog welds.
7. Vuam txheej txheem Compatibility:
- Qhov tseem ceeb:Cov txheej txheem vuam sib txawv yuav zoo dua rau cov khoom siv hlau.
- Kev txiav txim siab:Xaiv cov txheej txheem vuam uas sib haum nrog cov khoom siv hlau xaiv. Piv txwv li, qee cov hlau yuav xav tau cov cuab yeej tshwj xeeb lossis cov khoom siv tiv thaiv.
8. Khoom Thickness:
- Qhov tseem ceeb:Lub thickness ntawm cov khoom siv hlau tuaj yeem cuam tshuam cov vuam tsis.
- Kev txiav txim siab:Kho qhov vuam tsis, xws li tam sim no thiab siab, kom haum raws li qhov sib txawv ntawm cov khoom tuab. Xyuas kom meej tias lub tshuab welding xaiv tuaj yeem tswj tau qhov tshwj xeeb tuab ntawm cov hlau.
9. Pre-Welding Test:
- Qhov tseem ceeb:Kev kuaj welds lossis kev sim tuaj yeem pab ntsuas qhov weldability ntawm cov ntaub ntawv hlau.
- Kev txiav txim siab:Ua ntej ua qhov tseem ceeb ntawm cov welds, ua cov welds siv cov khoom siv hlau xaiv los ntsuas qhov zoo thiab kev ua haujlwm zoo.
Kev ntsuas qhov weldability ntawm cov ntaub ntawv hlau yog qhov tseem ceeb los xyuas kom meej tias kev ua tiav cable welds siv lub taub qab vuam tshuab. Kev txiav txim siab muaj xws li cov khoom sib xws, melting point, hluav taws xob conductivity, tshuaj muaj pes tsawg leeg, HAZ loj thiab cov khoom, kev sib koom ua ke, txheej txheem vuam sib xws, cov khoom tuab, thiab kev kuaj ua ntej vuam. Los ntawm kev ua tib zoo soj ntsuam cov xwm txheej no, cov neeg ua haujlwm tuaj yeem xaiv cov khoom siv hlau tsim nyog thiab cov khoom siv vuam, ua rau muaj kev ntseeg siab thiab zoo tshaj plaws cable welds rau ntau yam kev siv hluav taws xob.
