Nyob rau hauv lub realm ntawm txiv ntseej qhov chaw welding tshuab, tsim ntawm weld me ntsis yog ib tug tseem ceeb txheej txheem uas txiav txim siab lub zog thiab kev cia siab ntawm kev sib koom tes. To taub qhov intricacies ntawm cov txheej txheem tsim no yog qhov tseem ceeb rau kev ua tiav cov welds zoo hauv ntau daim ntawv thov. Qhov tsab xov xwm no delves rau hauv cov txheej txheem step-by-step ntawm yuav ua li cas weld me ntsis yog tsim nyob rau hauv cov txiv ntoo qhov chaw vuam tshuab.
- Kev Npaj Nto: Ua ntej pib txheej txheem vuam, qhov chaw ntawm cov khoom ua haujlwm thiab cov txiv ntoo yuav tsum tau muab ntxuav kom huv si kom tshem tawm cov kab mob lossis cov oxide txheej. Qhov no ua kom pom kev sib cuag ntawm cov hlau-rau-hlau, uas yog qhov tseem ceeb rau kev ua tiav qhov sib koom ua ke muaj zog thiab ruaj khov.
- Electrode Sib cuag: Raws li cov txiv ntoo qhov chaw vuam tshuab ua haujlwm, cov electrodes ua rau kev sib cuag nrog lub workpiece thiab txiv ntoo. Kev siv lub siab ua kom muaj kev sib txuas ntawm hluav taws xob thiab pib qhov ntws ntawm vuam tam sim no.
- Joule Cua sov: Qhov ntws ntawm vuam tam sim no los ntawm electrode thiab workpiece generates Joule cua sov ntawm qhov chaw ntawm kev sib cuag. Qhov no ua rau lub zos melting ntawm cov hlau ntawm lub interface, tsim ib tug molten weld pas dej ua ke.
- Thaum tshav kub kub Distribution: Thaum lub sij hawm welding txheej txheem, tshav kub faib ua lub luag haujlwm tseem ceeb hauv kev tswj qhov loj thiab qhov tob ntawm qhov chaw vuam. Kev faib hluav taws xob kom raug ua kom ntseeg tau tias cov hlau molten nkag mus rau hauv cov khoom ua haujlwm thiab cov txiv ntoo zoo, ua kom muaj kev sib raug zoo ntawm cov hlau.
- Solidification: Raws li qhov vuam tam sim no tsis tu ncua, cov hlau molten sai txias thiab solidifies, fusing lub workpiece thiab txiv ntseej ua ke. Cov txheej txheem solidification cuam tshuam cov cuab yeej cuab tam ntawm qhov chaw vuam, nrog rau nws lub zog thiab hardness.
- Cov nyhuv Annealing: Qee zaum, qhov chaw vuam yuav raug cuam tshuam los ntawm kev sib tsoo, qhov chaw uas muaj kev cuam tshuam los ntawm tshav kub muaj kev tswj kom txias kom txo tau qhov kev ntxhov siab thiab txhim kho kev sib koom ua ke.
- Kev soj ntsuam zoo: Tom qab cov txheej txheem vuam, cov chaw vuam yuav raug kuaj xyuas kom zoo kom ua raws li cov kev xav tau thiab cov qauv. Ntau yam kev sim uas tsis muaj kev puas tsuaj tuaj yeem ua haujlwm los ntsuas qhov kev ncaj ncees ntawm cov vuam.
Kev tsim cov txheej txheem ntawm cov pob zeb hauv cov txiv ntoo qhov chaw vuam tshuab yog qhov sib cuam tshuam ntawm hluav taws xob tam sim no, tsim hluav taws xob, thiab metallurgical fusion. Los ntawm kev npaj ua kom zoo zoo, kev siv cov vuam tam sim no, thiab cov khoom siv hluav taws xob kom zoo, cov khoom siv vuam zoo tau ua tiav, pab txhawb rau tag nrho lub zog thiab kev ua haujlwm ntawm cov pob qij txha welded. Kev nkag siab thiab ua kom zoo dua cov txheej txheem tsim no yog qhov tseem ceeb rau kev ua kom muaj kev ntseeg siab thiab ntev ntawm cov khoom siv welded hauv ntau daim ntawv thov kev lag luam.
