1. Welding Quality Issues
1.1. Weld Joint Cracking:
Ua rau: Kev ntxhov siab ntawm qhov sib koom ua ke los yog cov vuam tsis zoo, xws li kev tswj tsis raug vuam thiab kev sib tsoo vuam ceev.
Kev daws: Ua kom zoo tshaj qhov sib koom ua ke tsim, ntxiv dag zog vuam txheej txheem tswj, tswj vuam cua sov, thiab preheat qhov sib koom ua ke.
1.2. Weld suav nrog:
Ua rau: Hlau oxides lossis lwm yam impurities tsis raug tshem tawm tag nrho thaum vuam thiab raug kaw hauv qhov vuam.
Kev daws: Kho qhov vuam tsis zoo kom ntseeg tau tias tshem tawm cov hlau molten thiab oxides zoo; tsis tu ncua tshuaj xyuas thiab tswj cov cuab yeej los xyuas kom meej qhov chaw vuam huv.
1.3. Fusion tsis txaus:
Ua rau: vuam tsis txaus los yog vuam ceev heev, ua rau tsis tiav fusion ntawm vuam.
Kev daws: Ua kom vuam cua sov, txo vuam ceev, thiab ua kom tiav fusion ntawm vuam.
1.4. Gas Porosity:
Ua rau: Gas tsis raug tshem tawm tag nrho thaum lub sij hawm vuam thiab tseem nyob rau hauv lub vuam, tsim porosity.
Kev daws: Txhim kho qhov vuam ib puag ncig kom ntseeg tau tias cov pa roj du; kho qhov vuam tsis siv neeg kom txo tau lub sijhawm rau kev tsim roj.
1.5. Overlap Vuam:
Ua rau: Kev sib koom ua ke tsis zoo tshwm sim thaum ob lub npoo ntawm lub raj xa hluav taws xob sib tshooj, uas tshwm sim los ntawm axial txav ntawm cov menyuam extrusion, bearing puas, dabtsi yog khoov ntawm extrusion roller ncej, los yog ntau extrusion siab.
Kev daws: Txheeb xyuas thiab kho qhov chaw thiab qhov xwm txheej ntawm cov menyuam extrusion, hloov cov kabmob puas, xaiv qhov tsim nyog lub qhov thiab cov menyuam sib txawv, thiab kho tus nqi extrusion.
2. Cov khoom siv tsis ua haujlwm
2.1. Lub cev muaj zog tsis ua haujlwm:
Ua rau: Lub cev muaj zog tshaj, overheating, lossis kev laus.
Kev daws: Tsis tu ncua tshuaj xyuas lub cev muaj zog thiab tam sim hloov cov khoom siv lub cev muaj zog; xyuas kom meej tias lub cev muaj zog load nyob rau hauv ib tug tsim nyog ntau yam.
2.2. Mechanical Component Hnav:
Ua rau: Lub sijhawm ua haujlwm ntev ntawm cov cuab yeej ua rau cov khoom siv kho tshuab hnav.
Kev daws: tsis tu ncua hloov cov khoom hnav, ntxiv dag zog rau cov khoom siv tu; tsim nyog npaj cov kev npaj ntau lawm kom tsis txhob overloading cov cuab yeej.
2.3. Roj Pump Failure:
Ua rau: Roj twj tso kua mis clogging, roj to, los yog twj tso kua mis lub cev puas.
Kev daws: Tsis tu ncua tshuaj xyuas cov roj twj tso kua mis raws li txoj cai thiab sai sai ntxuav cov blockages; hloov cov twj tso kua mis puas lub cev lossis cov ntsaws ruaj ruaj.
3. Txheej txheem tswj cov teeb meem
3.1. Qhov tsis zoo Vuam Parameter Chaw:
Ua rau: Tsis tsim nyog teeb tsa rau vuam tam sim no, voltage, ceev, thiab lwm yam tsis.
Kev daws: Tsim nyog tsim cov kev ntsuas vuam raws li cov khoom siv vuam thiab cov lus qhia tshwj xeeb; tsis tu ncua calibrate thiab tshuaj xyuas cov khoom siv vuam kom paub meej qhov tseeb.
3.2. Induction Coil thiab impedance tsis zoo:
Yog vim li cas: Lub induction kauj thiab impedance tsis nyob rau ntawm qhov chaw zoo, cuam tshuam rau vuam zoo.
Kev daws: Kho qhov chaw ntawm induction coil thiab impedance rau lawv cov kev ua haujlwm zoo; tsis tu ncua tshuaj xyuas thiab tswj cov cuab yeej los xyuas kom meej qhov chaw ruaj khov.
3.3. Raw Material Issues:
Ua rau: Cov khoom tsis ruaj tsis khov ntawm cov hlau strips, deg defects, los yog loj geometric dimensional deviations.
Kev daws: Xaiv cov khoom siv raw khoom tsim nyog, ntxiv dag zog rau cov khoom siv tshuaj xyuas thiab kev lees paub; rov qab thiab hloov cov khoom tsis tsim nyog.
