Yuav ua li cas kho welding?
Cov lus nug no tsis tuaj yeem hais dav dav thiab yuav tsum tau txheeb xyuas raws li koj qhov xwm txheej tshwj xeeb.
Qhov zoo ntawm kev kho welding yog:
(1) Nws tuaj yeem kho qhov chaw puas los ntawm ntau yam laj thawj, xws li hnav, tawg, tawg, tawg, qhov, thiab lwm yam.;
(2) Feem ntau ntawm cov khoom siv hlau feem ntau tuaj yeem kho tau los ntawm vuam;
(3) Kev kho kom zoo yog qhov siab, thiab qee qhov muaj zog dua tom qab kho;
(4) Cov khoom tsim tau siab thiab tus nqi qis;
(5) Cov khoom siv vuam dav dav yog yooj yim, yooj yim rau kev khiav lag luam, thiab yooj yim rau kev kho thaj chaw.
Qhov tsis zoo ntawm kev kho vuam yog:
(1) Weld deformation thiab kev ntxhov siab. Cov cua sov hauv zos thiab tsis sib xws ntawm lub workpiece thaum kho vuam yog qhov ua rau vuam deformation thiab kev ntxhov siab. Thaum lub deformation ntau tshaj qhov tso cai, nws yuav tsum tau kho, uas tsis yog tsuas yog siv sij hawm, tab sis qee zaum txawm muab pov tseg vim qhov kev kho tsis zoo. Txhawm rau tiv thaiv thiab txo qhov deformation, qee qhov kev ntsuas tshwj xeeb feem ntau xav tau, xws li siv txoj kev rov qab deformation (uas yog, ua ntej vuam, qhov vuam yog deformed nyob rau hauv qhov kev taw qhia tsis sib haum los cuam tshuam qhov deformation los ntawm vuam) los tswj kev deformation, thiab siv lub rooj sib dhos thiab vuam ua ntu zus los tswj kev deformation.
(2) Vuam tawg. Kev tawg yog ib qho ntawm cov kev puas tsuaj ntau dua welding. Cov hlau cam khwb cia hlau thiab cov hlau tawv tawv yog qhov ua rau tawg thaum kho vuam, uas yog ib qho ntawm cov teeb meem tseem ceeb uas yuav tsum tau them sai sai rau thaum lub sij hawm vuam ua haujlwm.
(3) Porosity. Porosity yog ib qhov nyob rau hauv lub weld tshwm sim los ntawm cov roj nyob rau hauv lub vuam molten pas dej ua ke tsis muaj sij hawm los khiav thiab seem nyob rau hauv lub weld, uas muaj feem xyuam rau lub zog thiab sealing ntawm lub weld. Cov duab, qhov loj me, thiab tus naj npawb ntawm qhov pores muaj feem xyuam rau cov hlau hom ntawm cov khoom siv niam txiv, cov khoom ntawm lub vuam pas nrig, thiab kev kho vuam siv tshuab. Cov khoom xa tuaj kho muaj roj, xeb thiab lwm yam av. Yog tias lawv tsis raug tshem tawm tag nrho ua ntej welding, nws yog ib qho yooj yim ua rau pores.
(4) Lub zog ntawm kev kho qhov sib koom ua ke. Rau cov khoom hlau dav dav, qhov teeb meem no tsis loj. Txawm li cas los xij, rau cov ntaub ntawv uas tau raug tshav kub-kho thiab ntxiv dag zog, cov ntaub ntawv niam txiv ntawm ob sab ntawm lub vuam yuav raug hloov pauv hauv cov qauv thiab cov khoom sib xws tom qab raug cuam tshuam los ntawm tshav kub thaum kho vuam, thiab cov kev xav tau ntawm kev sib koom ua ke thiab cov khoom siv niam txiv. tsis yooj yim ntsib. Rau qhov me me, kev kho cua sov tag nrho tom qab kho vuam siv tau los daws qhov teeb meem. Nws yog tsis yooj yim sua kom ua tag nrho cov kev kho cua sov ntawm cov khoom loj. Lub sijhawm no, kev ntsuas yuav tsum tau ua raws li txoj kev vuam, cov khoom siv vuam thiab cov txheej txheem.
