Cov kua dej-cored vuam hlau, raws li lub npe qhia, tau ntim nrog cov flux tshwj xeeb. Qhov no flux melts thaum vuam, tsim cov roj tiv thaiv uas thaiv qhov chaw vuam thiab tiv thaiv cov cua sab nraud los ntawm kev cuam tshuam nrog cov vuam zoo.
Hlau Pub Ceev: Kev tswj xyuas qhov ruaj khov ntawm cov xaim pub ceev yog qhov tseem ceeb rau kev ua kom cov vuam zoo. Kev pub mis sai dhau tuaj yeem ua rau muaj qhov tsis xws luag xws li porosity, thaum pub mis qeeb dhau tuaj yeem cuam tshuam rau vuam efficiency. Yog li ntawd, hauv kev ua haujlwm tiag tiag, cov xaim pub ceev yuav tsum tau kho kom haum raws li cov khoom siv vuam, thickness, thiab vuam ceev.
Arc Length: Tswj qhov ntev arc yog qhov tseem ceeb sib npaug. Feem ntau, arc ntev ntawm 8-12mm yog qhov zoo tagnrho. Ib qho arc ntev ntev yuav ua rau tsis ruaj khov thiab tawg; thaum lub arc luv luv yuav ua rau overheating ntawm qhov chaw vuam, cuam tshuam qhov zoo ntawm vuam.
Vuam lub kaum sab xis: Qhov kev xaiv ntawm vuam lub kaum sab xis kuj ncaj qha cuam tshuam rau vuam zoo. Nws raug nquahu kom tig lub xaim rov qab 10-15 degrees thaum lub sijhawm vuam, uas ua rau lub vuam zoo nkauj dua thiab txo qhov tsis xws ntawm vuam.
Cov cua muaj zog ib puag ncig: Thaum vuam nyob rau hauv ib puag ncig cua muaj zog, nws yog ib qho tsim nyog yuav tsum tau ua kom tsim nyog ua kom muaj kev tiv thaiv roj ntws los txhim kho kev tiv thaiv. Yog tias cov roj shielding ntawm flux-cored hlau tsis txaus los tiv thaiv cov cua muaj zog, nws raug nquahu kom xav txog kev siv rub vuam ua haujlwm lossis nce cov khoom siv hluav taws xob sab nraud.
