Kev siv cov hlau tsis muaj hlau tau dhau los ua ntau dua, tsis muaj teeb meem hauv lub neej lossis kev tsim khoom, yog li peb yuav tsum muaj kev nkag siab tob txog nws. Kab lus no tham txog cov kev sib txuas ntawm cov hlau tsis muaj steel.
Ua ntej, tes soldering. Kev tuav vuam yog ib qho tshwj xeeb thiab feem ntau siv vuam txoj kev uas yooj yim rau kev khiav lag luam thiab yooj yim siv. Qhov ntev ntawm lub arc tuaj yeem hloov kho qhov tsim nyog los ntawm tus neeg teb xov tooj, thiab kev hloov kho yog ua raws li qhov sib txawv ntawm cov electrode thiab cov khoom ua haujlwm yuav tsum tau welded, thiab qhov ntev ntawm lub arc yog kho raws li qhov loj ntawm qhov sib txawv. Lub vuam pas nrig tsis yog tsuas yog siv los ua ib qho cuab yeej rau vuam stainless hlau, tab sis kuj tseem tuaj yeem siv los ua cov khoom ntim zoo rau cov vuam hauv qee qhov xwm txheej. Thiab cov khoom siv no tuaj yeem koom nrog stainless hlau workpieces kom ua tiav kev sib raug zoo dua.
Thib ob, hlau electrode gas-shielded vuam. Hlau gas-shielded vuam yog tsis siv neeg roj-shielded arc vuam. Nyob rau hauv tus txheej txheem ntawm kev siv txoj kev no, lub arc yog ignited thiab welded ntawm lub vuam hlau thiab stainless hlau workpiece nyob rau hauv lub confinement ntawm shielding roj. Lub vuam hlau pub los ntawm cov khoom siv vuam tshuab yog vuam pas nrig, uas yog yaj rau hauv cov kua stainless hlau hauv qab arc. Nyob rau hauv kev saib ntawm ntau yam thiab tshwj xeeb ntawm MAG vuam txoj kev, nws yog cov feem ntau siv vuam txoj kev nyob rau hauv lub stainless hlau vuam kev lag luam niaj hnub no. Thiab, vim nws ntau qhov zoo, nws yuav tsum yog txoj kev siv vuam ntau tshaj plaws rau lub sijhawm ntev.
Ntxiv dua thiab, tungsten inert gas shielded vuam. Nyob rau hauv no txoj kev ntawm kev siv, lub arc yog generated ntawm ib tug ruaj khov tungsten hluav taws xob vuam hlau thiab ib tug stainless hlau workpiece. Lub shielding roj siv nyob rau hauv no shielded vuam yog argon, thiab vuam hlau nws tus kheej pub los ntawm cov khoom siv vuam tsis siv neeg tsis raug them. Lub vuam hlau kuj tseem tuaj yeem xa tuaj, tab sis muaj qee qhov kev pheej hmoo. Raws li qee qhov tshwj xeeb, nws tsis tas yuav tsum pub cov khoom siv vuam vuam, thiab cov khoom siv hlau tsis muaj hlau yuav txiav txim siab seb puas yuav siv tam sim no. Yog tias siv tam sim no ncaj qha, tungsten vuam hlau yuav tsum tau teeb tsa raws li tus ncej tsis zoo, vim tias nws tus kheej muaj peev xwm nkag mus tau zoo heev, thiab nws muaj kev sib txuas zoo ntawm ntau hom stainless hlau.
