Hauv cov txheej txheem hlau sib txuas, arc vuam yog ib txoj kev siv vuam ntau tshaj plaws, feem ntau siv rau hauv cov khoom siv tsim khoom, cov khoom siv hluav taws xob sib txuas, thiab kev sib dhos precision. Txawm li cas los xij, vim yog kev coj tus cwj pwm ntawm lub cev thiab metallurgical koom nrog hauv kev sib txuas, xws li cov khoom siv hluav taws xob, cov pas dej molten, cov khoom siv hlau, thiab kev ntxhov siab, ntau yam vuam tsis xws luag tau yooj yim tsim, xws li undercut, weld hlaws, slag inclusions, thiab tawg. Cov kev tsis zoo no tsis yog tsuas yog cuam tshuam rau qhov zoo li vuam, tab sis kuj tuaj yeem txo cov txheej txheem lub zog thiab hluav taws xob conductivity. Vuam zoo yog qhov tseem ceeb tshwj xeeb tshaj yog thaum cuam tshuam nrog cov khoom tseem ceeb xws li brazed hluav taws xob tiv tauj lossis hluav taws xob sib txuas; Yog li ntawd, kev nkag siab zoo txog qhov ua rau muaj qhov tsis xws luag thiab kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb hauv engineering.
Ua ntej, hais txog qhov tsis xws luag, qhov tshwm sim tseem ceeb yog qhov ntau dhau ntawm cov hlau hauv lub hauv paus ntawm weld ntug, ua ib qho zawj -zoo li kev nyuaj siab. Hom kev tsis haum no feem ntau yog tshwm sim los ntawm kev siv vuam tam sim no ntau dhau, qhov ntev ntev arc, lossis kev siv hluav taws xob tsis raug. Thaum cov tam sim no siab dhau lawm, lub arc tshav kub input yog concentrated, ua rau hnyav melting ntawm lub hauv paus hlau ntug, thaum lub pas dej ua ke molten tsis sau nyob rau hauv lub sij hawm, yog li tsim undercut. Tsis tas li ntawd, kev txav ntawm electrode ceev heev lossis kev tswj lub kaum sab xis tuaj yeem ua rau lub pas dej tsis sib xws. Txhawm rau daws qhov teeb meem no, cov kev sib txuas vuam yuav tsum tau ua kom zoo los tswj cov khoom siv hluav taws xob, qhov tsim nyog tam sim no yuav tsum raug xaiv, thiab lub sijhawm nyob ntawm ntug bevel yuav tsum raug ncua kom tsim nyog los xyuas kom meej txaus molten pas dej ua ke. Nyob rau tib lub sijhawm, qhov ntev arc yuav tsum tau tswj kom tsis txhob muaj cua sov dispersion thiab tsis ruaj khov combustion vim yog qhov ntev ntev arc. Tswj undercut yog tshwj xeeb tshaj yog tseem ceeb nyob rau hauv kev sib cuag welding los yog precision conductive kev twb kev txuas txheej txheem kom tsis txhob muaj kev nyuaj siab nyob rau hauv lub cheeb tsam.
Qhov thib ob, weld hlaws yog lwm qhov tsis xws luag, feem ntau tshwm sim raws li cov hlau sib txuas hauv zos lossis sagging ntawm qhov chaw vuam. Qhov tshwm sim no feem ntau tshwm sim los ntawm kev siv vuam tam sim no ntau dhau, kev sib tsoo qeeb qeeb, lossis kev sib dhos ntau dhau. Tshwj xeeb tshaj yog nyob rau hauv ntsug los yog overhead vuam txoj hauj lwm, lub molten pas dej ua ke yog ntau yooj yim rau uncontrolled ntws vim lub ntiajteb txawj nqus. Cov tswv yim tswj sib txawv yuav tsum tau txais kev pom zoo rau txoj haujlwm vuam sib txawv. Piv txwv li, nyob rau hauv cov nyiaj siv ua haujlwm vuam, qhov tam sim no tuaj yeem raug txo kom tsim nyog los ntawm 15% mus rau 20%, thiab lub pas dej molten tuaj yeem tswj tau los ntawm "ceev ceev hauv nruab nrab, qeeb qeeb ntawm sab" vuam txheej txheem. Thaum lub sijhawm vuam ntsug, qhov kub ntawm lub pas dej molten yuav tsum tau tswj nruj me ntsis, thiab qhov txias yuav tsum tau ua tiav los ntawm kev cuam tshuam lossis nqa lub arc thaum tsim nyog. Tsis tas li ntawd, kev tswj xyuas qhov sib txawv ntawm bevel yog ib qho tseem ceeb ntawm kev tiv thaiv cov hlaws dai. Hauv cov txheej txheem cuam tshuam nrog Brazing Silver Contacts rau tooj liab tuav lossis nyiaj rau tooj liab Brazing, kev ruaj ntseg ntawm lub pas dej molten ncaj qha cuam tshuam rau kev sib koom ua ke ntawm kev sib koom tes.
Slag inclusions feem ntau tshwm sim raws li unmelted slag los yog oxides embedded nyob rau hauv lub weld, uas muaj peev xwm cuam tshuam rau lub weld qhov ceev thiab txhua yam khoom. Feem ntau ua rau muaj xws li vuam tam sim no tsis txaus, vuam ceev heev, thiab tsis ua kom sai tshem tawm slag thaum lub sij hawm ntau- txheej vuam. Tsis txaus tam sim no ua rau tsis txaus molten pas dej ua ke, tiv thaiv slag los ntawm tag nrho ntab mus rau saum npoo; conversely, ntau welding ceev ua rau slag mus rau hauv lub weld ua ntej nws yuav raug tshem tawm. Txhawm rau hais txog qhov no, cov kev sib txuas vuam yuav tsum tau hloov kho kom tsim nyog los xyuas kom muaj cov cua sov txaus, thiab cov txheej txheem ntxuav interpass yuav tsum tau ua raws li nruj me ntsis thaum lub sij hawm ntau- hla vuam. Tsis tas li ntawd, tsim nyog nce lub bevel lub kaum sab xis pab txhim kho molten pas dej ua ke ntws thiab txhawb nqa slag flotation. Hauv kev tsim cov txheej txheem ntawm Brazed Contacts lossis Brazed Hluav Taws Xob Cov Hluav Taws Xob, cov khoom siv sab hauv kom txo tau cov conductivity thiab yog li yuav tsum tau tswj kom zoo.
Cov kab nrib pleb yog ib qho kev puas tsuaj loj tshaj plaws, feem ntau cuam tshuam nrog kev ntxhov siab ntawm vuam, cov khoom muaj pes tsawg leeg, thiab qhov cua txias. Cov laj thawj feem ntau suav nrog kev txiav tawm arc sai heev, thermal stress concentration vim siab - vuam tam sim no, thiab qib siab ntawm cov khoom tsis zoo hauv cov khoom. Thaum lub sij hawm vuam, lub pas dej molten hlau solidifies thiab shrinks; yog tias kev ntxhov siab tsis tuaj yeem tso tawm, cov kab nrib pleb yuav tsim. Txhawm rau tiv thaiv cov kab nrib pleb zoo, ob qho tib si txheej txheem thiab cov khoom siv yuav tsum tau hais txog. Ntawm qhov tod tes, preheating lub workpiece txo cov cua txias thiab kub gradient, yog li txo cov thermal stress. Ntawm qhov tod tes, siv alkaline vuam electrodes pab txo qhov cuam tshuam ntawm cov khoom tsis zoo xws li sulfur thiab phosphorus ntawm kev ua haujlwm vuam. Tsis tas li ntawd, lub weld zoo yuav tsum tau optimized kom tsis txhob sib sib zog nqus, nqaim weld qauv, yog li txo cov kev ntxhov siab concentration. Nyob rau hauv siab - kev ntseeg siab koom nrog cov ntawv thov, xws li tooj liab Bars Nyiaj Sib cuag los yog koom nrog cov nyiaj sib cuag nrog tooj liab tuav los ntawm Brazing, kev tswj kev tawg yog ib qho tseem ceeb ntawm kev tswj kom zoo.
Ntxiv nrog rau qhov tsis xws luag uas tau hais los saum toj no, kev ua kom zoo tshaj plaws yog xav tau hauv kev tsim khoom tiag tiag, suav nrog cov txheej txheem tshwj xeeb. Piv txwv li, nyob rau hauv cov txheej txheem welding tsis kam xws li Resistance Spot Welding Silver Contact lossis Projection Welding Silver Contact, lub hom phiaj yuav tsum yog tswj xyuas qhov ceev tam sim no thiab siab kom ntseeg tau tias cov pob qij txha zoo sib xws; thaum nyob rau hauv Flash Welding Silver Contact lossis Resistance Seam Vuam Nyiaj Sib cuag, qhov cuam tshuam ntawm cov khoom siv hluav taws xob tas li ntawm cov khoom siv microstructure yuav tsum xav txog. Txawm hais tias cov txheej txheem vuam sib txawv muaj cov hauv paus ntsiab lus sib txawv, lawv cov ntsiab lus nyob hauv kev tswj cov cua sov thiab kev tswj xyuas kev ruaj ntseg ntawm lub pas dej.
Zuag qhia tag nrho, tiam ntawm arc vuam tsis xws luag muaj ntau yam -factor coupling yam ntxwv, nrog rau cov txheej txheem tsis, txoj kev khiav hauj lwm, thiab cov khoom siv. Tsuas yog los ntawm kev txheeb xyuas qhov systematic thiab kev tswj cov txheej txheem tuaj yeem vuam qhov zoo tuaj yeem txhim kho tau zoo. Hauv cov chaw tsim khoom niaj hnub no, nrog kev txhim kho ntawm automation thiab cov thev naus laus zis ntse, kev ruaj ntseg thiab kev tswj hwm ntawm cov txheej txheem vuam yog txhim kho tas li, tab sis kev nkag siab cov txheej txheem tseem ceeb tseem yog qhov yuav tsum tau ua ua ntej kom ntseeg tau qhov zoo.
