Vuam aluminium rods siv lub taub qab vuam tshuab tuaj yeem nyuaj vim cov khoom tshwj xeeb ntawm txhuas. Tsab ntawv xov xwm no tshawb nrhiav cov tswv yim zoo kom tsis txhob muaj qhov tsis xws luag thiab ua kom cov khoom siv welds zoo thaum siv lub tshuab aluminium pob tw vuam tshuab.
1. Kev huv huv yog qhov tseem ceeb:
- Qhov tseem ceeb:Ua kom huv si aluminium qhov chaw yog qhov tseem ceeb rau qhov tsis muaj qhov tsis xws luag.
- Kev Tiv Thaiv Kev Tiv Thaiv:Ua tib zoo ntxuav qhov kawg ntawm aluminium rods ua ntej vuam kom tshem tawm cov oxide txheej, av, los yog cov kab mob. Siv txoj kev tu kom tsim nyog, xws li txhuam hlau los yog tshuaj ntxuav, kom huv si.
2. Tswj Huab Cua:
- Qhov tseem ceeb:Aluminium yog reactive heev nrog oxygen thiab tuaj yeem tsim oxide txheej thaum vuam.
- Kev Tiv Thaiv Kev Tiv Thaiv:Ua vuam nyob rau hauv ib qho chaw tswj, xws li lub shielding gas chamber, kom tsis txhob raug cov pa oxygen. Qhov no minimizes oxide tsim thaum lub sij hawm vuam txheej txheem.
3. Kev haum zoo thiab kev sib tw:
- Qhov tseem ceeb:Kev sib haum xeeb thiab kev sib haum xeeb yog qhov tseem ceeb rau kev ua tiav aluminium rod welding.
- Kev Tiv Thaiv Kev Tiv Thaiv:Xyuas kom tseeb tias cov pas nrig kawg tau zoo sib xws thiab nruj nruj ua ke. Misalignment lossis qhov khoob tuaj yeem ua rau vuam tsis xws luag.
4. Optimal Welding Parameters:
- Qhov tseem ceeb:Qhov tsis raug welding tsis tuaj yeem ua rau cov khoom siv vuam tsis zoo thiab tsis zoo.
- Kev Tiv Thaiv Kev Tiv Thaiv:Teem lub vuam tsis, xws li tam sim no, voltage, thiab siab, nyob rau hauv qhov pom zoo ntau yam rau txhuas pas nrig vuam. Ua raws li lub tshuab tsim tawm cov lus qhia rau kev pom zoo.
5. Electrode Maintenance:
- Qhov tseem ceeb:Electrodes ua lub luag haujlwm tseem ceeb hauv cov txheej txheem vuam.
- Kev Tiv Thaiv Kev Tiv Thaiv:Tsis tu ncua tshuaj xyuas thiab tswj cov vuam electrodes. Xyuas kom lawv huv si, tsis muaj kev puas tsuaj, thiab ua kom zoo. Cov electrodes tsis huv los yog puas tuaj yeem ua rau vuam tsis xws luag.
6. Pre-Weld Testing:
- Qhov tseem ceeb:Kev kuaj welds pab txheeb xyuas cov teeb meem ua ntej vuam ntau lawm.
- Kev Tiv Thaiv Kev Tiv Thaiv:Ua cov kev ntsuam xyuas ua ntej-weld ntawm cov qauv rods los ntsuam xyuas qhov zoo ntawm vuam thiab kho qhov ntsuas yog tias tsim nyog. Qhov no tso cai rau cov neeg ua haujlwm kho kom zoo thiab tiv thaiv qhov tsis xws luag hauv cov khoom siv welds.
7. Kev soj ntsuam tom qab Weld:
- Qhov tseem ceeb:Kev kuaj pom pom yog qhov tseem ceeb rau kev txheeb xyuas qhov tsis xws ntawm vuam.
- Kev Tiv Thaiv Kev Tiv Thaiv:Tshawb xyuas thaj chaw welded visually rau tej yam tshwm sim ntawm qhov tsis xws luag, xws li tawg, voids, los yog tsis tiav fusion. Siv cov kev sim uas tsis yog kev puas tsuaj (NDT) xws li dye penetrant testing lossis ultrasonic test rau kev ntsuam xyuas ntau dua.
8. Ua kom txias txias:
- Qhov tseem ceeb:Kev txias nrawm tuaj yeem ua rau tawg thiab lwm yam tsis xws luag hauv txhuas.
- Kev Tiv Thaiv Kev Tiv Thaiv:Ua raws li cov txheej txheem tswj kev ua kom txias, xws li siv cov dej txias electrodes lossis tswj cov chav txias txias, kom ntseeg tau tias qhov txias txias txias tom qab vuam.
9. Kev cob qhia neeg ua haujlwm:
- Qhov tseem ceeb:Cov neeg ua haujlwm tau txais kev cob qhia zoo yog qhov tseem ceeb rau kev ua tiav aluminium rod welding.
- Kev Tiv Thaiv Kev Tiv Thaiv:Muab kev cob qhia zoo rau cov neeg ua haujlwm ntawm cov kev cov nyom tshwj xeeb thiab cov kev coj ua zoo tshaj plaws rau cov pas nrig aluminium vuam. Xyuas kom lawv paub meej txog cov khoom siv thiab cov khoom siv.
Vuam aluminium rods siv lub taub qab vuam tshuab yuav tsum tau saib xyuas kom meej thiab ua raws li cov kev coj ua tshwj xeeb kom tsis txhob muaj qhov tsis xws luag. Ua kom huv huv, tswj cov vuam cua, xyuas kom haum thiab ua kom zoo, siv qhov zoo ntawm vuam tsis zoo, tswj cov electrodes, ua ntej-weld xeem, ua tom qab vuam kev soj ntsuam, tswj cov cua txias, thiab muab kev cob qhia neeg ua hauj lwm yog qhov tseem ceeb tiv thaiv kev ntsuas. Los ntawm kev ua raws li cov kev coj ua no, cov neeg ua haujlwm tuaj yeem tsim cov welds tsis muaj qhov tsis xws luag thiab ua tiav cov txiaj ntsig zoo hauv cov ntawv thov aluminium rod taub qab vuam.
