Nyob rau hauv nruab nrab zaus inverter qhov chaw vuam, ua tiav cov khoom sib xws thiab zoo ib yam yog qhov tseem ceeb rau kev ua kom muaj kev ncaj ncees thiab kev ua haujlwm. Txawm li cas los xij, welds qee zaum tuaj yeem pom qhov tsis sib xws, qhov chaw ntawm qhov vuam zoo li tsis xwm yeem lossis pob. Kab lus no tshawb txog cov laj thawj feem ntau tom qab qhov tshwm sim ntawm qhov tsis sib xws hauv qhov nruab nrab zaus inverter qhov chaw vuam.
- Inconsistent Pressure: Tsis sib xws welds tuaj yeem tshwm sim los ntawm kev hloov pauv hauv qhov kev thov siab thaum lub sijhawm vuam txheej txheem. Tsis txaus los yog tsis sib npaug siab faib thoob plaws cov electrodes tuaj yeem ua rau cov cua sov hauv zos thiab tsis txaus fusion ntawm cov khoom ua haujlwm. Nws yog ib qho tseem ceeb uas yuav tsum tswj kom muaj lub siab sib xws thaum lub sijhawm ua haujlwm vuam los txhawb kev sib faib cov cua sov thiab tsim cov vuam kom zoo.
- Electrode Misalignment: Misalignment ntawm cov electrodes tuaj yeem ua rau tsis sib xws. Yog hais tias cov electrodes tsis raug raws li cov workpieces, tej zaum yuav muaj variations nyob rau hauv qhov chaw tiv tauj thiab tshav kub hloov lwm lub tsev, uas ua rau ib tug unevenly faib ntawm weld zog. Kev sib raug zoo ntawm cov electrodes yog qhov tseem ceeb los xyuas kom meej qhov sib txawv weld nkag mus thiab ib theem nto.
- Tsis txaus cua txias: Tsis txaus cua txias ntawm workpieces thiab electrodes tuaj yeem ua rau cov welds tsis sib xws. Thaum tshav kub kub ntau dhau thaum lub sij hawm vuam txheej txheem tuaj yeem ua rau lub hauv paus melting thiab irregular solidification, ua rau ib qho tsis sib xws. Cov txheej txheem ua kom txias kom zoo, xws li dej txias lossis cov tshuab ua kom txias, yuav tsum tau ua haujlwm los tswj qhov kub thiab txhawb kev tsim cov vuam zoo ib yam.
- Kev siv vuam tsis raug: Siv cov vuam tsis raug, xws li cov khoom siv vuam tam sim no ntau dhau lossis lub sijhawm vuam tsis txaus, tuaj yeem ua rau cov vuam tsis sib xws. Kev teeb tsa tsis raug tuaj yeem ua rau cua sov tsis sib xws thiab tsis txaus fusion, ua rau muaj qhov tsis sib xws ntawm cov hlaws weld. Nws yog ib qho tseem ceeb kom ua kom zoo dua cov vuam tsis raws li cov khoom siv, tuab, thiab kev sib koom ua ke kom ua tiav cov khoom sib xws.
- Workpiece Contamination: Kev sib kis ntawm qhov chaw ua haujlwm, xws li av, roj, lossis oxides, tuaj yeem cuam tshuam qhov zoo ntawm qhov vuam. Cov kab mob no tuaj yeem cuam tshuam cov txheej txheem vuam thiab tsim kev tsis sib xws hauv qhov chaw vuam. Kev npaj kom zoo, suav nrog kev tu thiab degreasing, yog qhov tseem ceeb los xyuas kom meej qhov chaw huv thiab tsis muaj kab mob sib kis.
Kev ua kom zoo ib yam thiab txawm tias welds hauv nruab nrab zaus inverter qhov chaw vuam yuav tsum tau saib xyuas ntau yam. Ua kom muaj kev sib haum xeeb, ua kom muaj kev sib haum xeeb ntawm electrode, ua raws li kev ntsuas cua txias kom zoo, ua kom cov vuam tsis zoo, thiab ua kom cov chaw ua haujlwm huv si yog qhov tseem ceeb rau kev txo qis qhov tsis sib xws. Los ntawm kev hais txog cov laj thawj no, cov neeg ua haujlwm tuaj yeem txhim kho tag nrho cov khoom zoo thiab cov tsos ntawm welds, ua rau muaj zog thiab txhim khu kev qha welded pob qij txha.
