Ua npuas ncauj ntawm Weld Points hauv Nruab Nrab Zaus Spot Vuam Tshuab?

Nruab nrab zaus qhov chaw vuam tshuab feem ntau yog siv los koom nrog cov khoom siv hlau hauv ntau qhov kev lag luam. Txawm li cas los xij, ib qho ntawm cov teeb meem uas cov neeg ua haujlwm yuav ntsib yog qhov tsim ntawm npuas lossis voids ntawm cov ntsiab lus weld. Kab lus no delves rau hauv cov laj thawj tom qab qhov tshwm sim ntawm npuas hauv nruab nrab zaus qhov chaw vuam thiab sib tham txog cov kev daws teeb meem los daws qhov teeb meem no.

Ua rau npuas ntawm Weld Points:

1. Contaminants ntawm qhov chaw:Ib qho ntawm thawj qhov ua rau npuas ntawm cov ntsiab lus weld yog qhov muaj cov kab mob, xws li roj, roj, xeb, lossis av, nyob rau saum npoo ntawm cov hlau raug welded. Cov kab mob no tuaj yeem vaporize thaum lub sij hawm vuam, ua rau cov npuas.
2. Oxidation:Yog tias cov hlau tsis huv lossis tiv thaiv zoo, oxidation tuaj yeem tshwm sim. Oxidized nto muaj peev xwm txo tau fuse thaum lub sij hawm vuam, ua rau muaj qhov khoob los yog voids.
3. Tsis txaus siab:Tsis sib haum lossis tsis txaus electrode siab tuaj yeem tiv thaiv cov hlau fusion zoo. Qhov no tuaj yeem ua rau muaj qhov sib txawv ntawm qhov chaw hlau, ua rau npuas tsim.
4. Inadequate Welding Tam sim no:Vuam nrog qhov tsis txaus tam sim no tuaj yeem ua rau tsis tiav fusion ntawm cov hlau. Yog li ntawd, qhov khoob yuav tsim, thiab npuas tuaj yeem tshwm sim vim cov khoom vaporized.
5. Electrode Contamination:Cov electrodes siv nyob rau hauv qhov chaw vuam tuaj yeem ua paug nrog cov khib nyiab dhau sijhawm, cuam tshuam rau qhov zoo ntawm qhov vuam. Cov electrodes tsis huv tuaj yeem ua rau tsis zoo fusion thiab muaj cov npuas.
6. Tsis yog Welding Parameters:Kev teeb tsa vuam tsis raug, xws li vuam tam sim no, lub sijhawm, lossis lub zog electrode, tuaj yeem ua rau tsis txaus fusion thiab tsim cov npuas.

Cov kev daws teeb meem rau Chaw nyob npuas ntawm Weld Points:

1. Kev npaj nto:Ua tib zoo ntxuav thiab degrease cov npoo hlau ua ntej vuam kom tshem tawm cov kab mob uas tuaj yeem ua rau muaj npuas.
2. Kev tiv thaiv nto:Siv cov tshuaj tiv thaiv oxidation uas tsim nyog los yog kev kho mob los tiv thaiv oxidation ntawm cov hlau nto.
3. Optimize Siab:Xyuas kom meej tias lub electrode siab zoo ib yam thiab tsim nyog rau cov ntaub ntawv welded. Lub siab txaus pab ua kom zoo fusion thiab tiv thaiv qhov khoob.
4. Corect welding tam sim no:Teem lub vuam tam sim no raws li qhov tshwj xeeb ntawm cov ntaub ntawv thiab cov txheej txheem vuam. Kev tsim nyog tam sim no yog qhov tseem ceeb rau kev ua tiav qhov muaj zog thiab tsis muaj npuas.
5. Regular Electrode Maintenance:Khaws cov electrodes kom huv si thiab tsis muaj cov khib nyiab kom ntseeg tau tias kev ua tau zoo thiab tiv thaiv cov teeb meem cuam tshuam.
6. Kev Kho Parameter:Muab ob npaug rau-xyuas thiab kho cov vuam tsis raws li qhov xav tau los xyuas kom meej fusion thiab txo qhov kev pheej hmoo ntawm kev tsim npuas.

Lub xub ntiag ntawm npuas ntawm cov ntsiab lus weld hauv nruab nrab zaus qhov chaw vuam tshuab tuaj yeem cuam tshuam qhov zoo thiab kev ncaj ncees ntawm cov welds. Kev nkag siab txog cov laj thawj ntawm qhov teeb meem no yog qhov tseem ceeb rau cov tswv lag luam kom ua raws li qhov tsim nyog ceev faj thiab siv cov kev daws teeb meem los tiv thaiv kev tsim npuas. Los ntawm kev npaj saum npoo kom zoo, tswj kom zoo ib yam, siv cov vuam tsis zoo, thiab ua kom cov electrode huv si, cov neeg ua haujlwm tuaj yeem txhim kho lawv cov txheej txheem vuam thiab tsim cov khoom zoo, tsis muaj npuas welds rau ntau yam kev siv.
