Kab lus no hais txog qhov muaj peev xwm welding anomalies uas yuav tshwm sim hauv lub taub qab vuam tshuab thiab qhia txog qhov tsim nyog yuav tsum tau ua los kho cov teeb meem no. Kev nkag siab yuav ua li cas los daws qhov tsis sib xws ntawm vuam yog qhov tseem ceeb rau kev ua kom zoo thiab kev ntseeg siab ntawm cov pob qij txha welded.
Taw qhia: Lub taub qab vuam tshuab yog tsim los xa cov txiaj ntsig zoo thiab siv tau zoo. Txawm li cas los xij, zoo li txhua txoj kev tsim khoom, vuam yuav ntsib qhov tsis zoo uas tuaj yeem cuam tshuam rau qhov zoo ntawm vuam. Kev txheeb xyuas thiab daws cov teeb meem tam sim no yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm cov pob qij txha welded.
- Tshawb xyuas Welding Parameters:
- Thaum ntsib kev tsis sib haum xeeb ntawm vuam, thawj kauj ruam yog los tshuaj xyuas qhov vuam tsis zoo, xws li vuam tam sim no, qhov hluav taws xob, thiab kev mus ncig ceev.
- Xyuas kom meej tias cov kev xaiv tsis haum rau cov khoom siv welded thiab ua raws li cov lus pom zoo los ntawm lub tshuab cov chaw tsim khoom.
- Txheeb xyuas Electrode Condition:
- Qhov xwm txheej ntawm vuam electrode plays lub luag haujlwm tseem ceeb hauv cov txheej txheem vuam. Tshawb xyuas cov electrode rau kev hnav, kev puas tsuaj, lossis kev sib kis.
- Hloov lossis rov kho cov electrode yog tias tsim nyog kom ua tiav qhov zoo tshaj plaws weld.
- Ntxuav qhov Vuam Nto:
- Cov impurities ntawm qhov chaw vuam tuaj yeem ua rau tsis zoo fusion thiab tsis muaj zog welds. Ua tib zoo ntxuav qhov chaw ua ntej welding.
- Siv cov kev tu kom tsim nyog, xws li degreasing lossis abrasive tu, kom tshem tawm cov kab mob.
- Txheeb xyuas qhov sib koom ua ke:
- Kev sib koom ua ke tsis raug tuaj yeem ua rau muaj kev sib raug zoo thiab ua rau muaj qhov tsis xws luag. Xyuas kom meej tias cov khoom uas raug welded yog raug raws thiab positioned.
- Ua ib qho kev hloov kho tsim nyog kom ua tiav kev sib koom ua ke kom haum.
- Saib xyuas Shielding Gas Flow:
- Rau cov txheej txheem vuam uas siv cov khoom siv tiv thaiv, xyuas kom cov roj ntws zoo ib yam thiab tsim nyog rau kev ua haujlwm vuam.
- Cov pa roj tsis txaus tuaj yeem ua rau muaj kev tiv thaiv tsis txaus, ua rau muaj qhov tsis xws li porosity lossis tsis tiav fusion.
- Tshawb xyuas Weld Quality:
- Tsis tu ncua tshuaj xyuas qhov zoo ntawm vuam thaum lub sij hawm vuam txheej txheem thiab tom qab nws tiav. Siv cov kev sim uas tsis yog kev puas tsuaj, xws li kev tshuaj xyuas qhov muag lossis kev kuaj ultrasonic, txhawm rau txheeb xyuas qhov tsis xws luag.
- Yog tias kuaj pom muaj qhov tsis xws luag, siv cov kev ntsuas tsim nyog los kho lawv, xws li rov vuam los yog kev kho dua tshiab.
Kev ntsib kev tsis sib haum xeeb hauv cov tshuab vuam pob tw tsis yog qhov tsis tshua muaj, tab sis hais kom lawv sai thiab tsim nyog yog qhov tseem ceeb rau kev ua tiav cov vuam zoo. Los ntawm kev tshuaj xyuas qhov ntsuas vuam, qhov ntsuas hluav taws xob, kev sib koom ua ke, thiab kev sib txuas zoo, cov neeg ua haujlwm tuaj yeem daws teeb meem zoo thiab daws cov teeb meem vuam. Kev saib xyuas tsis tu ncua, ua raws li cov qauv vuam, thiab kev cob qhia kom raug ntawm cov neeg ua haujlwm yog qhov tseem ceeb rau kev txo qis qhov tsis zoo ntawm vuam thiab ua kom muaj kev ua haujlwm zoo thiab kev nyab xeeb ntawm pob tw vuam.
