Welded Cheebtsam yog ib qho tseem ceeb uas tsim los ntawm vuam ob lossis ntau dua cov ntaub ntawv hlau. Cov txheej txheem sib dhos suav nrog tag nrho cov txheej txheem los ntawm kev ua cov khoom siv raw mus rau kev tsim thiab machining, ncaj qha txiav txim siab qhov tseeb ntawm cov khoom, cov khoom siv kho tshuab, thiab kev pabcuam kev ntseeg siab. Ib txoj kev sib sau ua ke yuav tsum ua raws li cov khoom siv thiab cov txheej txheem txheej txheem thaum tseem xav txog kev tsim khoom thiab kev tswj tus nqi; nws yog lub hauv paus tseem ceeb hauv kev ua tiav siab - kev sib txuas zoo hauv kev tsim khoom.
Thawj kauj ruam nyob rau hauv assembling welded Cheebtsam yog cov khoom pretreatment thiab sib dhos. Kev sib piv cov ntaub ntawv thiab cov khoom siv vuam yuav tsum raug xaiv raws li cov qauv tsim, thiab cov ntaub ntawv pov thawj thiab cov lus qhia tshwj xeeb yuav tsum tau txheeb xyuas qhov sib xws. Qhov chaw yuav tsum tau welded yuav tsum tau degreased, derusted, thiab descaled kom huv si interface rau fusion. Thaum sib sau ua ke, qhov khoob, misalignment, thiab bevel hom yuav tsum tau tswj. V-grooves, U-grooves, lossis ob npaug V-grooves feem ntau yog siv los ua kom haum cov thicknesses sib txawv thiab hom sib koom. Rau cov phaj tuab lossis cov qauv tseem ceeb, kev siv vuam ib ntus feem ntau siv los tiv thaiv kev hloov pauv thaum vuam.
Kev xaiv thiab kev siv cov txheej txheem vuam yog qhov tseem ceeb ntawm txoj kev sib dhos. Nyob ntawm cov khoom siv, cov txheej txheem nyuaj, thiab kev ua tau zoo, fusion vuam, siab vuam, lossis brazing tuaj yeem xaiv. Ntawm cov fusion vuam txoj kev, hluav taws xob arc vuam yog dav siv vim nws adaptability. Nws siv cov cua sov ntawm hluav taws xob arc los yaj cov khoom siv hauv paus thiab cov hlau muab tub lim los ua lub pas dej molten, uas tom qab ntawd crystallizes rau hauv ib qho txuas txuas ntxiv tom qab txias. Rau tuab- cov thawv ntim cov phab ntsa los yog kaw, submerged arc vuam tuaj yeem txhim kho kev ua haujlwm tau zoo thiab ua kom zoo sib xws. Rau siab -kev sib koom ua ke ntawm nyias daim hlau, roj shielded vuam feem ntau yog siv los txo deformation. Siab vuam, xws li qhov chaw vuam thiab kev sib txhuam vuam, tso siab rau kev siv tshuab siab thiab cua sov kom ua tiav cov khoom siv- lub xeev kev sib raug zoo thiab tsim nyog rau huab hwm coj- tsim cov khoom sib sib zog nqus. Brazing siv qhov qis- melting{12}} taw tes cov hlau ua kom ntub cov khoom siv hauv paus thiab sau qhov khoob, ua kom muaj kev sib koom ua ke ntawm cov hlau tsis sib xws lossis qhov tseeb.
Kev tswj cov txheej txheem thaum lub sij hawm tsim cov txheej txheem yog qhov tseem ceeb tshwj xeeb. Multi-txheej, ntau- hla vuam yuav tsum muaj qhov tsim nyog ntawm qhov sib txuas ntawm vuam thiab sib cuam tshuam qhov kub thiab txias kom sib npaug ntawm cov khoom siv hluav taws xob thiab txo qhov seem seem thiab deformation. Rau cov txheej txheem thav duab nrog tsis zoo rigidity, txoj kev xws li segmented rov qab - vuam thiab symmetrical vuam siv tau los tiv thaiv warping. Tom qab vuam, qhov tsim nyog tshaj tawm- ua tiav yog ua raws li kev tsim qauv, suav nrog kev tshem tawm slag thiab spatter, kho qhov loj me los ntawm kev siv tshuab, thiab tom qab-weld kho cua sov kom txo tau kev ntxhov siab thiab txhim kho microstructure.
Kev tshuaj xyuas zoo yog kev koom ua ke thoob plaws hauv tag nrho cov txheej txheem sib dhos. Ua ntej-weld verification, nyob rau hauv-weld xyuas, thiab post-weld non-kev soj ntsuam kev puas tsuaj rau ib tug kaw- voj tswj system los xyuas kom meej tias qhov teeb meem raug kuaj pom thiab hais tam sim ntawd. Hauv kev xaus, txoj kev sib dhos ntawm cov khoom siv welded yog kev sib koom ua ke ntawm cov ntaub ntawv, txheej txheem, thiab kev tswj hwm. Tsuas yog los ntawm kev sib koom ua kom zoo ntawm txhua qhov txuas tuaj yeem ua tau siab -tus qauv, siab- cov khoom zoo yuav raug tsim, muab lub hauv paus ruaj khov thiab txhim khu kev qha rau ntau hom khoom siv.
