Txiv ntseej projection welding yog ib txoj kev siv dav rau kev ruaj ntseg txuas ceev rau cov khoom hlau.Txawm li cas los xij, qee zaus ntawm xoob welds tuaj yeem tshwm sim, cuam tshuam lub zog thiab kev ncaj ncees ntawm kev sib koom ua ke.Tsab ntawv xov xwm no muab kev nkag siab txog cov laj thawj ua rau xoob welds hauv cov txiv ntoo projection welding thiab muab cov tswv yim daws teeb meem los daws qhov teeb meem no, ua kom muaj zog thiab txhim khu kev qha welds.
- Tsis txaus Vuam tam sim no: Ib qho ua tau ntawm cov welds xoob yog qhov vuam tsis txaus.Tsis txaus tam sim no yuav ua rau muaj cua sov tsis txaus, ua rau tsis muaj zog weld tsim.Txhawm rau hais txog qhov no, xyuas kom meej tias lub tshuab vuam tau raug kho kom raug thiab xa cov tam sim no tsim nyog rau cov txiv ntoo tshwj xeeb thiab cov khoom ua haujlwm ua ke.Kho qhov vuam tsis ua kom qhov tam sim no tuaj yeem pab ua kom muaj zog thiab txhim khu kev qha welds.
- Kev tsis zoo electrode Alignment: Kev sib dhos tsis raug ntawm cov electrodes kuj tuaj yeem ua rau xoob welds.Yog hais tias cov electrodes yog misaligned, lub siab siv thaum lub sij hawm vuam tej zaum yuav tsis muab sib npaug zos faib, uas ua rau ib tug tsis txaus daim ntawv cog lus ntawm cov txiv ntseej thiab lub workpiece.Xyuas kom tseeb tias cov electrodes raug ua kom raug thiab muab tso rau kom ntseeg tau tias kev sib cuag zoo thiab kev faib tawm siab.Tsis tu ncua tshuaj xyuas thiab kho cov electrode alignment raws li qhov tsim nyog.
- Lub sij hawm vuam tsis txaus: Lub sij hawm vuam tsis txaus tuaj yeem ua rau tsis tiav fusion thiab tsis muaj zog welds.Lub sijhawm ntawm cov txheej txheem vuam yuav tsum txaus los xyuas kom meej cov cua sov hloov thiab ua tiav ntawm cov txiv ntoo thiab cov khoom siv ua haujlwm.Tshawb xyuas cov kev qhia tshwj xeeb ntawm vuam thiab xyuas kom lub sijhawm vuam tsim nyog.Ua kom lub sijhawm vuam yog tias tsim nyog kom ua tiav cov vuam zoo dua thiab txhim khu kev qha.
- Kev sib kis los yog Oxidation: Kev sib kis los yog oxidation ntawm qhov chaw raug welded tuaj yeem cuam tshuam kev fusion thiab ua rau tsis muaj zog welds.Ua ntej vuam, xyuas kom meej tias cov txiv ntoo thiab cov khoom ua haujlwm huv si thiab tsis muaj cov kab mob, xws li roj, av, lossis xeb.Kev npaj kom zoo, suav nrog kev tu thiab degreasing, yog qhov tseem ceeb rau kev txhawb nqa kev tsim muaj zog.
- Material Compatibility: Cov ntaub ntawv tsis sib haum lossis tsis sib xws tuaj yeem ua rau cov welds tsis muaj zog.Xyuas kom meej tias cov txiv ntseej thiab cov khoom siv ua haujlwm tau sib xws thiab tsim nyog rau kev ua haujlwm vuam.Xav txog yam xws li cov khoom muaj pes tsawg leeg, hardness, thiab thermal zog los xyuas kom meej fusion thiab muaj zog weld tsim.
Hais txog xoob welds nyob rau hauv cov txiv ntoo projection welding yuav tsum tau ib tug systematic mus kom ze los txheeb xyuas thiab kho cov hauv paus ntsiab lus.Los ntawm kev hais txog cov teeb meem muaj feem cuam tshuam nrog vuam tam sim no, kev sib dhos electrode, vuam lub sijhawm, kev sib kis ntawm qhov chaw, thiab cov khoom siv sib raug zoo, cov tuam ntxhab tuaj yeem txhim kho qhov zoo thiab lub zog ntawm welds hauv cov txiv ntoo projection vuam daim ntawv thov.Kev saib xyuas tsis tu ncua, kev ntsuas kom raug, thiab ua raws li cov kev coj ua zoo tshaj plaws tuaj yeem pab ua kom cov welds muaj zog thiab txhim khu kev qha, ntxiv dag zog rau tag nrho cov kev sib koom ua ke.
