Taw qhia rau Spot Welding Galvanized Sheets nrog Nruab Nrab Zaus Inverter Spot Vuam Tshuab

Spot welding yog ib txoj kev siv dav rau kev koom nrog cov nplooj ntawv galvanized hauv ntau qhov kev lag luam. Galvanized nplooj ntawv, tseem hu ua galvanized steel lossis zinc-coated steel, muaj kev tiv thaiv corrosion zoo heev thiab kav ntev. Hauv tsab xov xwm no, peb yuav tshawb txog cov txheej txheem ntawm qhov chaw vuam galvanized nplooj ntawv siv nruab nrab zaus inverter chaw vuam tshuab, qhia txog cov kev xav tseem ceeb thiab cov tswv yim koom nrog.

1. Nkag siab Galvanized Sheets: Galvanized cov ntawv yog cov ntawv hlau uas tau coated nrog ib txheej ntawm zinc los tiv thaiv lawv ntawm corrosion. Lub zinc txheej muab ib txheej kev txi uas tiv thaiv cov hlau hauv qab los ntawm kev sib cuag ncaj qha nrog ib puag ncig ib puag ncig, yog li txo qhov kev pheej hmoo ntawm xeb tsim. Txawm li cas los xij, lub xub ntiag ntawm zinc txheej ua rau muaj kev nyuaj siab thaum lub sij hawm vuam qhov chaw, uas yuav tsum tau hais kom ua tiav cov welds txhim khu kev qha thiab zoo.
2. Kev xaiv electrode: Thaum qhov chaw vuam galvanized los xij, kev xaiv electrode yog qhov tseem ceeb. Kev txiav txim siab tshwj xeeb yuav tsum tau muab rau cov khoom siv electrode thiab txheej kom ntseeg tau tias muaj kev sib haum xeeb nrog cov galvanized nto. Nws raug nquahu kom siv cov khoom siv hluav taws xob ua los ntawm cov khoom siv xws li tooj liab alloys lossis cov khoom siv nrog cov khoom tiv thaiv kom txo tau qhov kev pheej hmoo ntawm zinc adhesion rau electrode nto.
3. Kev Tu thiab Kev Npaj Nto: Kev tu kom zoo thiab kev npaj saum npoo yog qhov tseem ceeb ua ntej qhov chaw vuam galvanized nplooj ntawv. Cov zinc txheej ntawm cov ntawv yuav muaj cov impurities, xws li roj, av, lossis oxides, uas tuaj yeem cuam tshuam cov txheej txheem vuam thiab cuam tshuam qhov vuam zoo. Kev tu kom huv si siv cov kuab tshuaj tsim nyog lossis cov tshuaj degreasers yog tsim nyog los tshem tawm cov kab mob thiab xyuas kom meej qhov chaw vuam huv.
4. Vuam Parameters: Spot vuam tsis ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov welds txhim khu kev qha ntawm cov ntawv galvanized. Lub vuam tam sim no, vuam lub sij hawm, thiab lub zog electrode yuav tsum tau ua tib zoo kho kom zoo rau qhov muaj cov zinc txheej. Cov vuam tam sim no siab dua thiab lub sijhawm vuam ntev dua feem ntau yuav tsum tau ua kom muaj kev sib xyaw ua ke ntawm cov ntawv galvanized. Lub electrode quab yuam kuj yuav tsum tau teem kom tsim nyog los tsim kom muaj kev sib cuag txaus thiab txhawb kom txaus hloov cua sov thaum lub sij hawm vuam txheej txheem.
5. Kev kho tom qab Weld: Tom qab qhov chaw vuam galvanized los xij, nws yog qhov tseem ceeb los daws cov teeb meem cuam tshuam nrog cov txheej txheem vuam. Ib qho kev txhawj xeeb yog qhov tsim ntawm zinc spatter, uas yuav tshwm sim vim vaporization ntawm zinc txheej thaum vuam. Txhawm rau txo qhov no, kev kho tom qab vuam xws li zinc spatter tshem tawm lossis ntxuav saum npoo yuav tsim nyog kom ua tiav qhov huv thiab zoo nkauj zoo nkauj.

Spot welding galvanized sheets siv nruab nrab zaus inverter chaw vuam tshuab muaj txoj hauv kev txhim khu kev qha thiab siv tau zoo rau kev koom nrog cov ntaub ntawv no. Los ntawm kev xav txog yam xws li kev xaiv electrode, kev tu kom zoo thiab kev npaj saum npoo, kev ua kom zoo dua vuam tsis zoo, thiab kev kho tom qab vuam, cov tuam ntxhab tuaj yeem ua tiav cov vuam zoo ntawm cov ntawv galvanized. Qhov no ua rau kev tsim cov khoom siv ruaj khov thiab tiv taus corrosion, ua rau nruab nrab zaus inverter qhov chaw vuam tshuab yog ib qho cuab yeej tseem ceeb hauv kev lag luam uas ua haujlwm nrog cov hlau galvanized.
