Feem ntau, steel hlau hlua tsis tuaj yeem welded. Nov yog cov laj thawj tshwj xeeb:
Cov Khoom Siv Teeb Meem: Cov hlua hlau hlau feem ntau yog ua los ntawm siab - carbon steel hlau, uas tsis zoo weldability. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov hlua hlau uas muaj ntau cov hlua ntawm cov hlau nyias nyias, qhov twg cov hlau nyias nyias ua rau qhov nyuaj ntawm vuam.
Cov khoom siv tseem ceeb: Cov hlua hlau hlau feem ntau muaj cov tub ntxhais ua los ntawm cov ntaub ntawv xws li nylon lossis hlua yas. Thaum lub sij hawm vuam, cov cua sov tuaj yeem ua rau cov ntaub ntawv tseem ceeb no kub hnyiab, cuam tshuam rau tag nrho kev ua haujlwm ntawm cov hlua hlau hlau.
Txoj kev sib txuas: Hauv kev siv cov tswv yim, steel hlau hlua feem ntau txuas nrog siv snap- haum txoj kev sib txuas, tsis yog vuam. Txoj kev no yog ob qho tib si yooj yim thiab txhim khu kev qha, ua tau raws li qhov xav tau ntawm feem ntau daim ntawv thov scenarios.
