Vuam tsis xws luag tuaj yeem tshwm sim thaum lub sijhawm vuam, cuam tshuam qhov zoo thiab kev ncaj ncees ntawm vuam. Paub txog kev kho kom zoo los daws cov teeb meem no yog qhov tseem ceeb rau cov vuam thiab cov kws tshaj lij uas siv lub tshuab vuam taub qab. Kab lus no tshawb txog cov tswv yim los kho qhov tsis xws ntawm vuam, qhia txog lawv qhov tseem ceeb hauv kev ua tiav cov welds txhim khu kev qha thiab zoo.
Kev Kho Kom Zoo rau Vuam Defects hauv Butt Vuam Tshuab:
- Porosity: Txhawm rau kho qhov porosity, uas zoo li qhov me me hauv qhov vuam, cov vuam yuav tsum xyuas kom zoo tu thiab degreasing ntawm qhov chaw ua haujlwm ua ntej vuam. Tswj cov roj ntws thiab siv cov vuam tsis raug, xws li tam sim no thiab voltage, kuj tuaj yeem pab tiv thaiv porosity.
- Tsis muaj Fusion: Nyob rau hauv cov ntaub ntawv ntawm tsis txaus fusion ntawm cov khoom siv vuam thiab cov hauv paus, cov vuam yuav tsum ua kom cov vuam tam sim no los yog txo cov vuam ceev los txhim kho kev nkag mus. Kev npaj kom zoo, haum, thiab kev sib koom ua ke yog qhov tseem ceeb los xyuas kom muaj kev sib haum xeeb txaus.
- Undercut: Txhawm rau hais txog qhov tsis zoo, qhov zawj lossis kev nyuaj siab ntawm cov npoo npoo, cov vuam tuaj yeem txo qhov vuam tam sim no lossis nrawm los tswj cov cua sov. Kev tswj kom zoo ntawm cov vuam electrode thiab tsis txhob siv ntau dhau los kuj tseem tuaj yeem pab tiv thaiv kev txiav.
- Tshaj Weld Spatter: Txo cov vuam tam sim no thiab kho cov xaim pub ceev tuaj yeem txo qis qhov sib tsoo ntau dhau, uas yog hais txog cov tee hlau raug tshem tawm thaum vuam. Kev ntxuav cov chaw ua haujlwm thiab siv cov roj thaiv kev tsim nyog tuaj yeem pab tiv thaiv kev tawg.
- Cracking: Txhawm rau kho qhov tawg, cov welders tuaj yeem siv cov txheej txheem preheating, kev kho cua sov los yog kev ntxhov siab. Tsim kom zoo sib koom ua ke, xaiv cov khoom siv, thiab zam kev txias txias tuaj yeem tiv thaiv kev tawg.
- Incomplete Penetration: Ua kom vuam tam sim no, kho lub kaum sab xis electrode, los yog siv cov electrode loj tuaj yeem txhim kho kev nkag mus thiab kho qhov nkag tsis tiav. Kev npaj ua ke kom raug thiab tsis txhob sib koom ua ke ntau dhau kuj tseem ceeb heev.
- Misalignment: Misalignment ntawm workpieces yuav kho tau los ntawm realigning thiab repositioning lawv kom raug. Kev tsim nyog clamping thiab kev siv cov khoom siv thaum lub sij hawm vuam tuaj yeem pab tiv thaiv qhov tsis zoo.
Hauv kev xaus, kev nkag siab txog kev kho cov kev ntsuas rau vuam qhov tsis xws luag hauv lub taub qab vuam tshuab yog qhov tseem ceeb rau kev ua tiav cov welds txhim khu kev qha thiab zoo. Hais txog porosity, tsis muaj fusion, undercut, ntau weld spatter, cracking, incomplete penetration, thiab misalignment muaj ntau yam txuj ci thiab kev kho nyob rau hauv vuam tsis. Los ntawm kev siv cov tswv yim no, welders thiab cov kws tshaj lij tuaj yeem txhim kho cov txheej txheem vuam, tiv thaiv qhov tsis xws luag, thiab ua tau raws li cov qauv kev lag luam. Kev hais txog qhov tseem ceeb ntawm kev ntsuas kev kho mob txhawb nqa kev nce qib hauv vuam thev naus laus zis, txhawb kev ua tau zoo hauv cov hlau koom nrog ntau yam kev siv hauv kev lag luam.
