Kev daws qhov tsis zoo Weld zoo nyob rau hauv nruab nrab-Frequency Inverter Spot Welding Machine?

Kev ua tiav cov welds zoo yog qhov tseem ceeb hauv kev tsim khoom, tshwj xeeb tshaj yog thaum siv cov khoom siv nruab nrab zaus inverter chaw vuam tshuab. Tsis zoo weld zoo tuaj yeem ua rau cov qauv tsis muaj zog, txo cov khoom lag luam, thiab nce nqi ntau lawm. Kab lus no muab kev nkag siab txog cov teeb meem uas ua rau cov vuam tsis zoo nyob rau hauv nruab nrab zaus inverter qhov chaw vuam tshuab thiab qhia cov kev daws teeb meem los daws cov teeb meem no zoo.

1. Insufficient Weld Penetration: Insufficient weld penetration tshwm sim thaum lub vuam tsis nkag mus rau hauv lub workpiece, ua rau cov pob qij txha tsis muaj zog. Yuav kom daws tau qhov teeb meem no, muaj ntau yam ua tau:

• Kho Vuam Parameters: Ua kom lub vuam tam sim no, vuam lub sij hawm, los yog electrode quab yuam los txhim kho cov cua sov tsim thiab xyuas kom zoo fusion ntawm workpieces.
• Txhim kho Electrode Tsim: Ua kom zoo dua cov duab electrode thiab loj los txhim kho cov cua sov hloov thiab txhim kho kev nkag mus. Xav txog kev siv taw tes lossis tapered electrodes kom mloog zoo rau cov cua sov ntawm qhov chaw weld.
• Clean Workpiece Surfaces: Xyuas kom meej tias cov chaw ua haujlwm yog huv si thiab tsis muaj kab mob, xws li roj, xeb, lossis xim. Kev npaj saum npoo kom zoo txhawb kev sib txuas zoo dua.

2. Inadequate Nugget Formation: Inadequate nugget formation yog hais txog qhov tsim tsis tsim nyog ntawm molten hlau nugget thaum lub sij hawm vuam txheej txheem. Qhov no tuaj yeem ua rau cov welds tsis muaj zog lossis tsis tiav. Cov kauj ruam hauv qab no tuaj yeem pab daws qhov teeb meem no:

• Optimize Welding Parameters: Kho qhov vuam tam sim no, vuam lub sij hawm, los yog electrode quab yuam kom ua tiav cov cua kub zoo uas yuav tsum tau ua kom tsim nyog.
• Xyuas kom zoo Electrode Alignment: Xyuas kom tseeb tias cov electrodes tau ua raws kom raug los xyuas kom meej qhov sib txawv ntawm qhov siab thiab qhov chaw sib cuag txaus.
• Siv cov khoom siv hluav taws xob tsim nyog: Xaiv cov khoom siv hluav taws xob nrog cov khoom siv hluav taws xob tsim nyog thiab cov khoom siv hluav taws xob los pab txhawb kev tsim cov txiaj ntsig zoo.

3. Electrode Contamination: Kev sib kis ntawm cov electrode nto, xws li oxides los yog txawv teb chaws, tuaj yeem cuam tshuam qhov zoo ntawm vuam. Txhawm rau txo qhov teeb meem no:

• Ntxuav thiab hnav khaub ncaws Electrodes: Tsis tu ncua ntxuav thiab hnav cov lus qhia electrode kom tshem tawm cov kab mob hauv lub cev. Kev saib xyuas electrode kom zoo pab tswj xyuas qhov zoo sib xws.
• Siv Cov Txheej Txheem Tiv Thaiv: Siv cov tshuaj tiv thaiv kab mob lossis cov yeeb yaj kiab tiv thaiv ntawm electrode nto kom txo tau cov kab mob sib kis thiab txo kev sib tsoo.

4. Inconsistent Electrode Force: Inconsistent electrode quab yuam tuaj yeem ua rau muaj kev hloov pauv hauv qhov zoo ntawm vuam. Yuav daws qhov teeb meem no:

• Siv Lub Zog Saib Xyuas Kev Ruaj Ntseg: Siv lub zog saib xyuas lossis cov sensors kom ntseeg tau tias muaj zog electrode zoo ib yam thoob plaws hauv cov txheej txheem vuam. Cov tshuab no tuaj yeem muab cov lus tawm tswv yim tiag tiag thiab hloov kho lub zog yog tias muaj kev sib txawv.
• Tsis tu ncua Calibrate Electrode Force: Periodically calibrate lub electrode quab yuam kom paub tseeb thiab sib xws. Kho lub zog raws li qhov xav tau los tswj qhov zoo ntawm qhov vuam zoo.

Kev daws qhov tsis zoo weld zoo nyob rau hauv nruab nrab zaus inverter qhov chaw vuam tshuab yuav tsum tau ua kom zoo. Los ntawm kev hais txog cov teeb meem xws li tsis txaus weld nkag mus, tsim tsis txaus nugget, electrode contamination, thiab inconsistent electrode quab yuam, manufacturers tuaj yeem txhim kho weld zoo thiab xyuas kom ntseeg tau thiab ruaj khov pob qij txha. Ua raws li cov txheej txheem vuam kom zoo, txhim kho kev tsim hluav taws xob zoo, tswj cov electrodes huv si, thiab xyuas cov electrode quab yuam ua rau muaj kev sib raug zoo thiab zoo welds. Kev cob qhia tsis tu ncua thiab saib xyuas cov neeg ua haujlwm weld kuj tseem ceeb los txheeb xyuas thiab kho txhua yam teeb meem tam sim ntawd. Nrog rau cov kev ntsuas no nyob rau hauv qhov chaw, manufacturers tuaj yeem txhim kho weld zoo, txo qis rework, thiab txhim kho tag nrho cov khoom tsim tau thiab cov neeg siv khoom txaus siab.
