Cov ntaub ntawv tsim nyog ntawm cov roj thaiv hluav taws xob vuam yog cov txheej txheem kev nkag siab ntau heev uas yuav tsum tau nkag siab tob ntawm Vuam cov txheej txheem thiab kev ceev faj kom daws cov tsis xws luag. Ntawm no yog nthuav dav, cov ntsiab lus tshaj lij ntawm cov txheej txheem:
1. Cov kev paub yooj yim ntawm cov roj thaiv cov pa hluav taws xob vuam
Cov kev thaiv cov vuam vuam, uas suav nrog TIG (GTAW), MIG (GMAW), yog ib lub taub ntim thaiv kom tiv thaiv cov pa weld los ntawm cov pa weld los ntawm cov pa weld los ntawm cov pa weld Kev xaiv ntawm cov pa roj hmab yog qhov tseem ceeb, raws li nws tuaj yeem cuam tshuam qhov zoo ntawm Weld thiab cov khoom ntawm welded cov khoom siv.
2. Kev cim thiab ua rau vuam tsis xws luag
Vuam tsis xws luag xws li porosity, tsis tiav nkag mus, thiab kev tawg tuaj yeem tshwm sim vim muaj ntau yam. Porosity tuaj yeem tshwm sim los ntawm kev ya raws lossis roj nkag hauv lub pas dej weld, thaum ua tsis tiav kev nkag mus thiab tawg tau los ntawm kev xaiv tsis thwj.
3. Kev daws teeb meem
Txhawm rau hais cov kev tsis xws luag no, cov kev daws teeb meem yuav tsum ua kom haum rau qhov tshwj xeeb:
- Porosity: Xyuas kom meej tias qhov chaw vuam yog huv thiab tsis muaj cov ntaub ntawv paug los tiv thaiv cov porosity.
- Tsis ua tiav nkag mus: Kho cov vuam kho kom haum thiab txheej txheem los tswj cov tswv yim tshav sov, kom dhau los ua rau nkag mus tsis muaj kev nkag siab ntawm cov khoom siv.
- Nrib pleb: Siv cov khoom siv tub lim thiab ua cov txheej txheem vuam, thiab preheat cov hlau los txo qhov cua txias kom sov, uas tuaj yeem pab tiv thaiv kom txhob muaj kev tawg.
4. Vuam Kev Tswj Xyuas Zoo
Kev tswj kom zoo hauv vuam yog qhov tseem ceeb rau kev ua kom muaj kev ncaj ncees thiab kev ntseeg tau ntawm welded pob qij txha. Qhov no cuam tshuam nrog kev soj ntsuam nyuaj, kev ua kom muaj kev soj ntsuam cov txheej txheem tshwj xeeb (WPS), thiab kev siv cov kev sim tsis yog - ndt) los kuaj pom sab hauv.
5. Cov txheej txheem kev ua haujlwm ruaj khov
Cov Txheej Txheem Ua Haujlwm Nyab Xeeb (sops) yog qhov tseem ceeb rau kev tswj kev phom sij kev nyab xeeb thiab kev ua raws li kev ua raws li kev lag luam kev lag luam. Cov txheej txheem no qhia txog cov lus qhia ib qib zuj zus rau kev ua cov haujlwm vuam kom nyab xeeb thiab muaj txiaj ntsig.
Lub ntsiab
Daim ntawv thov kev vam meej ntawm cov roj kev thaiv kev siv tshuab kev sib tw ntawm cov qauv vuam, los ntawm cov ntsiab cai ua kom muaj kev txheeb xyuas thiab cov kev daws teeb meem. Los ntawm kev siv nruj zoo tswj kev ntsuas, ua raws li cov qauv kev nyab xeeb, txo cov kev tsis sib xws, thiab paub meej txog kev nyab xeeb thiab kev nyab xeeb ntawm welded qauv.
