Hlau vuamyog cov txheej txheem kev lag luam hloov tau yooj yim uas tuaj yeem sib txuas ntau hom hlau. Txoj kev sculptural no tau hloov kev tsim khoom los ntawm kev ua kom muaj peev xwm tsim cov khoom siv hlau nyuaj thiab muaj zog. Hlau vuam, uas muaj ntau tshaj 40 hom kev sib txawv, tau dhau los ua ib feem tseem ceeb ntawm ntau qhov kev lag luam, suav nrog cov tsheb, tsev, thiab aerospace sectors.
Fusion welding yog ib qho ntawm cov subcategories tseem ceeb ntawm cov hlau vuam. Txhawm rau txuas cov khoom siv hlau ncaj qha, cov txheej txheem cuam tshuam ob qho tib si lub workpiece thiab solder. Muaj ntau txoj hauv kev los muab cov cua sov uas xav tau rau kev sib txuas vuam, nrog rau cov nplaim taws, hluav taws xob arcs, thiab lasers. Raws li lawv txias thiab solidify tom qab melted ua ke, lub workpiece thiab solder tuaj ua ke los tsim ib tug ruaj khov daim ntawv cog lus.
Lwm hom hlau welding yog siab vuam. Cov txheej txheem no siv lub siab los txuas cov hlau, raws li lub npe xav tau. Lub siab vuam tsis cuam tshuam cov hlau melting, sib piv rau fusion vuam. Hloov chaw, lub zog siv deforms thiab compresses cov khoom, ua ib qho khoom sib txuas uas tsis tuaj yeem sib cais. Thaum yuav tsum muaj kev sib txuas ntawm lub zog siab lossis thaum sib txuas cov hlau nrog qhov sib txawv ntawm qhov sib txawv, qhov no yuav pab tau zoo heev.
Ib hom thib peb ntawm cov hlau vuam yog brazing. Nws entails siv brazing alloys raws li cov ntaub ntawv muab tub lim los txuas cov khoom hlau. Thaum brazing, as opposed to fusion welding, muab cov ntaub ntawv nrog cov ntsiab lus melting qis dua cov niam txiv hlau tuaj yeem siv tau.Lub brazing alloy yog rhuab mus rau nws melting point (feem ntau qis dua lub workpiece) thiab ces ntws los ntawm capillary txiav txim ntawm cov hlau qhov chaw. tsim kom muaj zog, txhim khu kev qha sib koom ua ke.
Kev cai hlau vuamyog qhov tseem ceeb rau ntau lub lag luam vim nws ua kom yooj yim los tsim ntau yam khoom. Vuam yog siv nyob rau hauv kev lag luam automotive los sib sau ua ke lub thav duab, tso qhov system, thiab cav qhov chaw. Nws ua kom lub tsheb muaj kev ruaj ntseg thiab kev nyab xeeb. Hlau vuam yog siv nyob rau hauv kev tsim kho los koom nrog steel beams, rebar, thiab pipelines, kom ruaj khov thiab tensile lub zog ntawm cov qauv thiab infrastructure. Txhawm rau kom ntseeg tau qhov kev ntseeg siab thiab kev ncaj ncees ntawm cov dav hlau, vuam kuj tseem ua haujlwm nyob rau hauv aerospace sector los tsim cov roj tso tsheb hlau luam, cov khoom siv cav, thiab cov qauv dav hlau.
Kev sib txawv automated thiab robot-assisted vuam tshuab tau tsim los ntawm kev txhim kho hauv kev siv tshuab hlau vuam. Cov kev txhim kho no tsis yog tsuas yog txhawb nqa cov khoom tsim tawm thiab raug, tab sis kuj tseem ua rau cov neeg ua haujlwm muaj kev nyab xeeb los ntawm kev txo lawv qhov cuam tshuam rau cov xwm txheej txaus ntshai. Tsis tas li ntawd, lub koos pij tawj tswj kev vuam tshuab tso cai rau kev rov ua dua thiab raug, ua rau muaj kev sib raug zoo, zoo welds.
Txawm hais tias hlau vuam muaj ntau yam txiaj ntsig, nws kuj muaj qee yam kev nyuaj. Cov txheej txheem yuav tsum muaj cov kws tshaj lij thiab cov kws paub zoo uas muaj kev paub txog qhov sib txawv ntawm cov txheej txheem vuam thiab cov khoom hlau. Tsis tas li ntawd, cov teeb meem xws li distortion, porosity, thiab residual stresses yuav tshwm sim thaum lub sij hawm vuam, cuam tshuam rau cov qauv kev ncaj ncees ntawm cov khoom kawg. Yog li ntawd, ua tib zoo npaj, ua tib zoo ua kom zoo thiab kev tswj xyuas nruj yog qhov tseem ceeb los xyuas kom meej qhov kev ntseeg tau thiab kev ua tau zoo ntawm cov khoom siv hlau welded.
Nyob rau hauv xaus, hlau vuam yog ib tug ntau yam thiab indispensable hlau koom txheej txheem. Nrog nws cov welding ntau, gluing thiab brazing txoj kev, nws muaj qhov kawg possibilities rau fabricating thiab engraving hlau cov khoom. Los ntawm lub tsheb mus rau kev tsim kho thiab kev lag luam aerospace, hlau vuam ua lub luag haujlwm tseem ceeb hauv kev ua kom lub zog, ua haujlwm ntev thiab kev nyab xeeb ntawm ntau yam khoom. Nrog rau kev nce qib ntawm kev siv thev naus laus zis, hlau vuam thev naus laus zis yuav undoubtedly txuas ntxiv txhim kho, ntxiv txhim kho kev ua tau zoo, precision thiab zoo ntawmwelded qhov chaw.
