Yog vim li cas rau Welding Joints nyob rau hauv nruab nrab zaus Spot Vuam tshuab?

Nruab nrab zaus qhov chaw vuam yog cov txheej txheem siv dav hauv ntau qhov kev lag luam rau kev koom nrog cov khoom siv hlau.Txawm li cas los xij, muaj qee zaus qhov kev sib txuas ua ke uas tsim los ntawm cov tshuab no yuav tsis tuav ruaj khov raws li qhov xav tau.Kab lus no delves rau hauv cov laj thawj muaj peev xwm tom qab tsis muaj zog vuam pob qij txha hauv nruab nrab zaus qhov chaw vuam tshuab.

1. Tsis txaus siab:Ib qho ntawm cov laj thawj tseem ceeb rau cov pob qij txha tsis muaj zog yog qhov tsis txaus siab thaum lub sijhawm vuam txheej txheem.Kev siab zoo yog qhov tseem ceeb los xyuas kom muaj kev ruaj ntseg ntawm cov khoom siv hlau.Yog tias lub siab tsis txaus, qhov sib txuas vuam yuav tsis tsim kom raug, ua rau muaj qhov tsis muaj zog.
2. Lub sijhawm tsis raug:Nruab nrab zaus qhov chaw vuam yuav tsum tau lub sij hawm meej kom ua tiav cov txiaj ntsig zoo.Yog tias lub sijhawm vuam lub sijhawm luv luv lossis ntev dhau, nws tuaj yeem cuam tshuam qhov zoo ntawm cov vuam sib txuas.Lub sij hawm tsis zoo tuaj yeem ua rau tsis tiav ntawm cov hlau nto, ua rau muaj kev sib koom ua ke tsis muaj zog.
3. Electrode Contamination:Kev sib kis ntawm cov vuam electrodes tuaj yeem cuam tshuam qhov vuam zoo.Cov electrodes qias neeg lossis corroded yuav tsis ua hluav taws xob zoo, ua rau cov cua sov tsis sib xws thiab cov pob qij txha tsis muaj zog thaum kawg.Kev saib xyuas electrode tsis tu ncua yog qhov tseem ceeb los xyuas kom muaj kev ua haujlwm zoo.
4. Kev teeb tsa fais fab tsis txaus:Nruab nrab zaus qhov chaw vuam tshuab muaj ntau lub zog teeb tsa kom haum rau cov khoom sib txawv thiab cov kev xav tau sib koom ua ke.Yog tias qhov chaw fais fab tsis zoo sib xws rau cov khoom siv tshwj xeeb raug welded, nws tuaj yeem ua rau cov cua sov tsis txaus, ua rau cov pob qij txha tsis muaj zog.
5. Material Incompatibility:Cov hlau sib txawv muaj qhov sib txawv conductivity thiab cov ntsiab lus melting.Thaum cov hlau sib txawv tau raug welded ua ke, ua tiav kev sib koom ua ke muaj zog tuaj yeem nyuaj.Qhov sib txawv ntawm cov khoom siv tuaj yeem ua rau cov cua sov tsis sib xws thiab tsis muaj zog ntawm kev sib koom ua ke.
6. Cov txheej txheem vuam tsis zoo:Kev ua haujlwm zoo ntawm lub tshuab vuam yog qhov tseem ceeb rau kev tsim cov pob qij txha muaj zog.Kev cob qhia tsis txaus lossis cov txheej txheem tsis raug los ntawm tus neeg teb xov tooj tuaj yeem ua rau cov welds tsis sib xws, ua rau muaj kev sib koom ua ke tsis muaj zog.
7. Tsis Muaj Kev Npaj Pre-Weld:Kev npaj saum npoo yog qhov tseem ceeb rau kev ua tiav cov pob qij txha muaj zog.Yog hais tias cov hlau tsis zoo huv si thiab npaj ua ntej welding, lub xub ntiag ntawm cov kab mob los yog oxides tuaj yeem cuam tshuam kev sib xyaw kom zoo, ua rau cov pob qij txha tsis muaj zog.
8. Txias tus nqi:Kev ua kom txias sai ntawm cov welded sib koom ua ke tuaj yeem ua rau nws nkig thiab tsis muaj zog.Kev ua kom zoo tom qab vuam txias yog tsim nyog los tso cai rau kev sib koom ua ke kom khov thiab ntxiv dag zog maj mam.

Hauv kev xaus, kev ua tiav cov kev sib koom ua ke muaj zog thiab txhim khu kev qha hauv nruab nrab zaus qhov chaw vuam tshuab yuav tsum tau saib xyuas ntau yam.Lub siab txaus, lub sijhawm raug, huv si electrodes, kev teeb tsa hluav taws xob zoo, cov khoom siv sib raug zoo, kev ua haujlwm txawj, kev npaj ua ntej vuam, thiab kev tswj kom txias yog txhua yam tseem ceeb hauv kev tsim cov welds.Los ntawm kev hais txog cov xwm txheej no, cov tuam ntxhab thiab cov neeg ua haujlwm tuaj yeem ua kom ntseeg tau tias cov khoom siv vuam tau ua tau raws li cov qauv kev xav tau thiab nthuav tawm lub zog tsim nyog rau lawv cov kev xav tau.
