Nruab nrab zaus qhov chaw vuam yog cov txheej txheem siv dav hauv kev tsim khoom lag luam rau kev koom nrog cov hlau ua ke.Ib theem tseem ceeb hauv kev ua haujlwm ntawm qhov nruab nrab zaus qhov chaw welder yog lub hwj chim-on cua sov theem.Nyob rau theem no, cov cuab yeej siv vuam xa cov hluav taws xob tswj hluav taws xob rau cov khoom ua haujlwm, tsim kom muaj thaj chaw hauv cheeb tsam ntawm kev kub siab ntawm cov ntsiab lus sib cuag.
Thaum lub sij hawm lub hwj chim-on cua sov theem, qhov nruab nrab zaus qhov chaw welder siv ib tug alternating tam sim no (AC) nrog ib tug zaus ntawm 1000 mus 10000 Hz.Qhov nruab nrab zaus AC no raug xaiv vim tias nws cuam tshuam qhov sib npaug ntawm cov kev hloov pauv siab thiab qis zaus.Nws tso cai rau kev hloov hluav taws xob zoo thiab kev tswj xyuas meej ntawm cov txheej txheem cua sov.
Lub zog-on cua sov theem ua haujlwm rau ntau lub hom phiaj tseem ceeb hauv qhov chaw vuam txheej txheem.Ua ntej, nws preheats cov hlau qhov chaw, txo cov thermal poob siab thaum siv qhov tseeb vuam tam sim no.Qhov cua sov no maj mam txo qis cov khoom sib txawv thiab pab tswj cov txheej txheem kev ncaj ncees ntawm cov welded sib koom.
Qhov thib ob, cov cua sov hauv zos softens cov hlau qhov chaw, txhawb kev zoo hluav taws xob conductivity ntawm workpieces.Qhov no yog qhov tseem ceeb heev rau kev ua tiav qhov sib xws thiab txhim khu kev qha.Cov hlau softened kuj tseem pab tshem tawm cov kab mob hauv qhov chaw xws li oxides, ua kom muaj kev sib txuas huv huv.
Tsis tas li ntawd, lub hwj chim-on cua sov theem plays lub luag hauj lwm nyob rau hauv ua kom tiav metallurgical transformation.Raws li cov hlau heats li, nws cov microstructure hloov, ua rau txhim kho weld zog thiab durability.Qhov kev tswj xyuas theem no ua kom ntseeg tau tias cov khoom siv tau zoo dua qub, tsis yog kev cuam tshuam.
Lub sij hawm ntawm lub hwj chim-on cua sov theem nws txawv raws li tej yam xws li hom hlau welded, nws thickness, thiab qhov xav tau welding tsis.Niaj hnub nimno nruab nrab zaus qhov chaw vuam tshuab yog nruab nrog sophisticated tswj systems uas kho lub sij hawm cua sov thiab lub zog tawm tswv yim raws li qhov tshwj xeeb yuav tsum tau ntawm txhua vuam ua hauj lwm.
Nyob rau hauv xaus, lub hwj chim-on cua sov theem nyob rau hauv ib tug nruab nrab zaus qhov chaw welder yog ib tug tseem ceeb kauj ruam nyob rau hauv lub vuam txheej txheem.Nws preheats lub workpieces, txhim kho hluav taws xob conductivity, ntxuav lub qhov chaw, thiab pab rau metallurgical kev txhim kho.Cov theem no qhia txog qhov tseeb thiab kev hloov pauv ntawm cov txheej txheem tsim khoom niaj hnub, ua kom muaj zog thiab txhim khu kev qha welds rau ntau yam kev siv.
