Tsis tiav fusion yog ib qho kev puas tsuaj uas tshwm sim thaum lub vuam hlau tsis ua tiav nrog lub hauv paus hlau, ua rau cov pob qij txha tsis muaj zog lossis tsis txaus.Nyob rau hauv lub zog cia qhov chaw vuam tshuab, ua tiav tag nrho fusion yog qhov tseem ceeb rau kev ua kom muaj kev ncaj ncees thiab kev ntseeg siab ntawm cov khoom siv welded.Kab lus no tsom mus rau cov tswv yim thiab cov tswv yim los daws thiab kho qhov tsis tiav fusion hauv lub zog cia chaw vuam tshuab.
- Kho qhov vuam tsis zoo: Kev kho qhov vuam tsis zoo yog qhov tseem ceeb rau kev txhawb nqa kom zoo fusion.Tsis muaj xws li vuam tam sim no, voltage, thiab ntev yuav tsum tau ua tib zoo kho raws li cov khoom thickness thiab cov khoom.Ua kom cov vuam tam sim no tuaj yeem muab cov cua sov ntau ntxiv thiab txhim kho fusion, thaum kho cov electrode siab tuaj yeem pab xyuas kom muaj kev sib cuag thiab nkag mus.Nrhiav qhov zoo tshaj qhov sib npaug ntawm qhov tsis sib xws yog qhov tseem ceeb rau kev ua tiav fusion tiav.
- Txhim kho Kev Npaj Khoom Siv: Kev npaj cov khoom siv tau zoo ua lub luag haujlwm tseem ceeb hauv kev ua kom tiav fusion kom raug.Ua ntej vuam, nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav thiab npaj cov chaw ua haujlwm kom tshem tawm cov kab mob, oxides, lossis cov txheej txheem uas tuaj yeem cuam tshuam fusion.Tsis tas li ntawd, kev sib xyaw kom haum thiab kev sib haum xeeb ntawm cov khoom ua haujlwm yuav tsum tau ua kom txo qis qhov sib txawv thiab xyuas kom muaj cua sov kom zoo thaum vuam.
- Txhim khu kev sib koom ua ke: Kev tsim qauv sib koom ua ke ua lub luag haujlwm tseem ceeb hauv kev ua kom tiav fusion.Kev txiav txim siab yuav tsum tau muab rau kev sib koom geometry, nrog rau kev xaiv ntawm qhov tsim nyog zawj cov ces kaum, cov hauv paus khoob, thiab kev npaj ntug.Ib qho kev sib koom ua ke zoo nrog kev nkag mus rau qhov chaw ntawm electrode tuaj yeem pab txhawb kev xa tawm kom sov thiab nkag mus, txhim kho fusion zoo.
- Kev Ua Haujlwm Preheating Techniques: Nyob rau hauv rooj plaub uas tsis tiav fusion txuas ntxiv, kev siv cov txheej txheem preheating tuaj yeem muaj txiaj ntsig.Preheating lub workpieces ua ntej vuam yuav pab ua kom lub hauv paus hlau kub, txhawb kev weldability zoo dua thiab fusion.Cov txheej txheem no yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov ntaub ntawv uas muaj cov thermal conductivity siab lossis tsis tshua muaj cua sov input rhiab heev.
- Siv Kev Kho Mob Tom Qab Kub Kub: Yog tias tsis tiav fusion raug kuaj pom tom qab vuam, kev kho cua sov tom qab vuam tuaj yeem ua haujlwm los kho qhov teeb meem.Cov txheej txheem kev kho cua sov xws li annealing lossis kev ntxhov siab tuaj yeem siv rau cov khoom siv welded los txhawb kev sib txuas ntawm metallurgical thiab txhim kho fusion ntawm lub interface.Cov txheej txheem no yuav pab txo qis kev ntxhov siab thiab txhim kho cov cuab yeej cuab tam ntawm vuam.
Kev hais txog qhov tsis tiav fusion hauv lub zog cia qhov chaw vuam tshuab yuav tsum muaj txoj hauv kev zoo uas suav nrog kev txhim kho vuam tsis zoo, txhim kho cov khoom siv, txhim kho kev sib koom ua ke, siv cov txheej txheem preheating, thiab siv cov txheej txheem tom qab vuam thaum tsim nyog.Los ntawm kev siv cov tswv yim no, cov neeg ua haujlwm tuaj yeem txo qhov tshwm sim ntawm qhov tsis tiav fusion, kom ntseeg tau tias muaj zog thiab txhim khu kev qha vuam pob qij txha hauv lub zog cia qhov chaw vuam daim ntawv thov.
