1. Tsis zoo vuam zoo
Performance: Nquag txias dua vuam vuam, spattering thiab hlawv-dhau.
Ua rau:
Irrational parameter teeb.
Electrode hnav lossis paug.
Kev tiv thaiv kev ntsuas:
Tsim lintaws tau teeb tsa vuam tsis thiab kho tam sim no, voltage thiab vuam ceev raws li welding cov ntaub ntawv thiab workpiece thickness.
Txheeb xyuas thiab hloov cov hluav taws xob lossis cov hluav taws xob tsis tu ncua.
2. Vuam tsis xws luag
Kev Ua Tau Zoo: Cov Khaub Thuam, Weld choj, tsa cov ntaub qhwv.
Ua rau:
Impropter vuam parameter teeb, xws li vuam tam sim no, voltage, vuam ceev, thiab lwm yam.
Kev tsis raug vuam cov ntaub ntawv, xws li vuam hlau, vuam pas nrig lossis vuam roj.
Kev tiv thaiv kev ntsuas:
Tsim lintaws tau teeb tsa vuam qhov tsis yog raws li cov ntaub ntawv vuam thiab cov ua haujlwm tuab.
Siv cov ntaub ntawv vuam ntawm cov khoom zoo ib yam kom ntseeg tau tias muaj cov roj av vuam ruaj khov.
3. Vuam cracks
Kev Ua Tau Zoo: Ntev tawg tawg, transverse cracks, arc kev tawg pleb, thiab lwm yam tshwm sim hauv cov pob qij txha vuam.
Ua rau:
Vuam kev ntxhov siab thiab lwm yam xwm txheej sawv ua ke.
Lub vuam tam sim no loj dhau los yog dhau me me, thiab cov xaim pub mis ceev ceev nrawm nrawm lossis qeeb qeeb.
Kev tiv thaiv kev ntsuas:
Xaiv cov txheej txheem vuam tsim nyog los tswj lub vuam tam sim no thiab nrawm.
Siv preheating thiab tom qab kev kho mob sov kom txo qis kev siv hlau ntxhov siab.
IV. Swb slag inclusus
Kev Ua Tau Zoo: Tsis yog xim hlau suav nrog hauv lub weld tom qab vuam.
Ua rau:
Txuas ntxiv vuam tsis muaj kev txhuam cov nplais thaum lub sijhawm vuam.
Lub vuam tam sim no yog qhov me me heev, thiab cov hlau molten thiab swb muaj fluidity tsis zoo.
Kev tiv thaiv kev ntsuas:
Ua tib zoo tshem tawm lub ntsej muag ntawm ntug ntawm Weld thiab Weld txheej.
Xaiv cov vuam tsim nyog tam sim no kom ntseeg tau tias lub slag tuaj yeem ntab.
V. Tsis Txaus Nkag Nkag
Kev Ua Tau Zoo: Lub hauv paus ntawm kev sib koom ua ke yog tsis tag nkag mus rau hauv vuam.
Ua rau:
Lub zeem muag lub ces yog me me, lub rooj sib txoos sib dhos yog me me lossis sab tsis yog lawm.
Lub vuam tam sim no yog me me thiab lub vuam ceev nrawm heev.
Kev tiv thaiv kev ntsuas:
Xaiv cov groove kaum sab xis thiab sib dhos sib txawv.
Kho lub vuam tam sim no thiab ceev kom ntseeg tau tias tus weld yog tag nrho nkag mus.
6. Arc khawb
Kev Ua Tau Zoo: Hauv zos puas tsuaj los ntawm kev ua arcing lossis arcing rau ntawm cov khoom siv hauv paus sab nraum qhov zawj.
Cause: Kev ua haujlwm wlocropper.
Kev tiv thaiv kev ntsuas:
Xyuas kom meej tias kev txiav vuam ob tog yog lawm.
Tus tswv cuab yuav tsum muaj kev ua haujlwm txawj ntse thiab raug.
7. Qhib txias shrinkage
Kev Ua Tau Zoo: Qhov tsim tawm los ntawm Molten hlau thaum Solmification.
Cause: Ceev Arc Extinguishing thaum lub sij hawm vuam thiab tsis sib xws ceev ceev ntawm lub pas dej molten.
Kev tiv thaiv kev ntsuas:
Tsis txhob tso tseg tam sim ntawd thaum tua hluav taws ARC, thiab sau cov pas dej hauv pas dej Molten kom haum.
Siv ob-ntu kev nkag mus rau txoj kev vuam.
8. Hlawv-dhau los
Performance: perforations tsim nyob rau ntawm ib lossis ntau qhov chaw hauv weld thaum vuam.
Cause: Lub vuam tam sim no loj heev thiab lub sijhawm vuam ntev heev.
Kev tiv thaiv kev ntsuas:
Kho lub vuam tam sim no thiab lub sijhawm kom tsis txhob muaj ntev ntev thiab ntev dhau vuam.
9. Hluav taws xob tsis ua tiav ntawm vuam cov khoom siv
Kev ua tau zoo: Lub tshuab vuam tsis tuaj yeem pib, lub zog hluav taws xob tsis ruaj khov, thiab cov vuam tam sim no yog txawv txav.
Cause: Fais Fab Kab tsis ua haujlwm, Vuam Lub Zog Ua tsis tiav.
Kev tiv thaiv kev ntsuas:
Xyuas cov kab hluav taws xob muaj zog tsis tu ncua kom ntseeg tau tias lub zog hluav taws xob ruaj khov.
Ua lub ntsej muag vuam siv hluav taws xob tsis tu ncua thiab hloov chaw laus hauv lub sijhawm.
