1. Vuam tam sim no
Nrog rau qhov nce ntawm vuam tam sim no, kuj nce qhov tob ntawm fusion thiab weld residual qhov siab, weld dav tsis hloov ntau, vim hais tias thaum vuam tam sim no nce, kuj nce lub tshav kub hloov mus rau weldment, lub arc quab yuam ntawm lub pas dej ua ke kuj nce. , yog li qhov tob ntawm fusion nce, nrog rau qhov nce ntawm vuam tam sim no, tus nqi ntawm melting ntawm cov hlau nce, kom qhov seem seem ntawm qhov vuam nce, thiab rov qab, qhov tob ntawm fusion thiab qhov seem seem yog txo.
Thaum lub vuam tam sim no loj dhau lawm, qhov tob ntawm fusion yog tob dua, qhov dav ntawm vuam seam tsis hloov pauv, qhov kub ntawm qhov cuam tshuam loj heev, uas yuav ua rau kub hnyiab los ntawm kev sib tsoo thiab weld aneurysm thiab lwm yam tsis xws luag, uas yuav ua rau nws nyuaj rau. lub pas dej molten ntawm cov pa roj thiab suav nrog rau ntab thiab khiav tawm, thiab nws yooj yim rau qhov tsis xws luag xws li cov pa roj, slag thiab cov kab nrib pleb kom tshwm sim hauv cov vuam, thiab tam sim no me me dhau, qhov tob ntawm fusion tsis txaus, thiab nws yog yooj yim los tsim qhov tsis xws luag xws li tsis zoo fusion, tsis-welded-los ntawm thiab slag, yog li thaum lub vuam tam sim no nce, nws yog ib qho tsim nyog yuav tsum tau ua kom lub arc voltage, xyuas kom meej qhov sib txuas weld dav thiab txhim kho vuam zoo.
2.Arc voltage
Nyob rau hauv cov ntaub ntawv ntawm lwm yam tsis hloov, raws li lub arc voltage nce, lub weld dav kuj nce, qhov seem qhov siab thiab qhov tob ntawm fusion txo, lub arc voltage thiab arc ntev yog proportional rau lub arc voltage nce, kuj nce lub arc ntev, lub arc heats li thaj tsam ntawm weldment kuj nce, nce qhov dav ntawm weld seam, nyob rau tib lub sij hawm, nrog rau qhov nce nyob rau hauv lub arc ntev, lub tshav kub yuav siv los yaj lub flux, tab sis tus nqi ntawm welding hlau melting. tsis nce tus nqi ntawm cov hlau melted yog faib rau hauv cheeb tsam loj, yog li qhov seem ntawm qhov siab ntawm weld seam yuav txo. Qhov seem ntawm qhov siab ntawm qhov vuam yuav raug txo, ntxiv rau, vim qhov nce ntawm qhov ntev ntawm qhov arc, nws yuav ua rau arc oscillation, lub zog ntawm lub pas dej melting tsis muaj zog, kom qhov tob ntawm fusion ua me. Nyob rau hauv submerged arc vuam, lub arc voltage yog hloov raws li lub vuam tam sim no los xyuas kom meej qhov ruaj khov combustion ntawm arc, yog li qhov ntau ntawm kev hloov pauv ntawm arc voltage yog txwv.
Txawm li cas los xij, thaum lub arc voltage siab dhau lawm, nws yuav tsis tsuas yog txo qhov tob ntawm fusion, ua rau tsis tiav vuam, tab sis kuj ua rau tsis zoo weld shaping, slag tshem tawm nyuaj, thiab txawm tias tsis xws li tom ntug, yog li cov vuam tam sim no yuav tsum. yuav tsum tau nce kom tsim nyog nyob rau tib lub sij hawm raws li qhov arc voltage yog nce.
3.Vuam ceev
Lwm yam vuam tsis hloov tsis hloov, qhov vuam ceev nce, vuam cov tswv yim kub yog txo, txo qhov vuam qhov tob, tus nqi ntawm cov hlau melting yog txo, weld dav thiab seem qhov siab yog txo, vuam ceev yog siab dhau, tus nqi. ntawm melted hlau yog tsis txaus, yuav muaj ib tug tsis muaj weld-los ntawm, tom thiab lwm yam tsis xws luag, nyob rau hauv thiaj li yuav xyuas kom meej qhov zoo ntawm weld, yuav tsum tau rau ib tug tej yam nqi ntawm weld tshav kub input, piv txwv li, nce lub vuam ceev nyob rau hauv kev txiav txim. txhawm rau ua kom cov khoom tsim tau thiab qhov sib txuam nce hauv vuam tam sim no thiab arc voltage. Txhawm rau kom ntseeg tau qhov vuam zoo, nws yog qhov yuav tsum muaj qee qhov vuam cua sov tawm tswv yim, piv txwv li, ua kom cov vuam ceev kom txhim kho cov khoom tsim tau, thiab ua kom cov vuam tam sim no thiab arc voltage raws li.
4.Txoj kab uas hla thiab qhov ntev ntawm vuam hlau
Thaum lub vuam tam sim no, vuam ceev thiab arc voltage tsis hloov, txoj kab uas hla ntawm cov hlau yog txawv, cov duab ntawm vuam hloov, nyob rau hauv lwm yam kev mob tseem tsis hloov, txoj kab uas hla ntawm cov hlau thiab qhov tob ntawm fusion yog inversely proportional rau qhov nce. nyob rau hauv tam sim no ceev thiab txo, vim hais tias qhov nce nyob rau hauv tam sim no ceev, tab sis kuj nce tus nqi ntawm molten hlau, nrog rau cov molten hlau nce, weld rau hauv cov duab tsis zoo, submerged arc vuam, kom cov arc voltage thiab vuam tam sim no rau xyuas kom cov seam zoo li tus.
Lwm qhov kev sib txuas tsis hloov pauv, thaum lub xaim ntev nce, qhov kev tiv thaiv kuj nce ntxiv, txhim kho cov nyhuv preheating ntawm qhov txuas ntxiv ntawm cov hlau, ua kom cov hlau yaj nrawm nrawm, ua rau qhov tob ntawm fusion, qhov seem seem nce, yog cov hlau txuas ntev dhau lawm, nws yuav ua rau cov kab hluav taws xob tsis zoo hauv qab cov hlau liab, yog li ntawd, qhov ntev ntawm cov hlau yuav tsum tau tswj, yuav tsum tsis txhob ntev dhau.
