Puas yog cov kav hlau tsis kam ncaj ncaj ncaj ncaj ncaj heev yog tias nws tawg?

Cov xaim tawm yog siv los tsim cua sov thiab yuav tsum tau ua haujlwm kub heev, koj yuav tsum tau txuas rau ob qho kev tawm tsam yog tawg, uas yog hais, cov cua sov tsim, cov cua sov tsim ntawm lub Kev ua kom loj heev yog loj, thiab qhov kub yog qhov siab siab. Nws yog ib qho yooj yim rau rov qab ree-liarcuit rau tawg {}}

Thaum ntsib cov teeb meem xws li, nws yog qhov tsim nyog kom nkag siab cov khoom ntawm cov hlau uas tsis kam, cov neeg hlau tsis kam siv, thiab lwm yam .

Piv txwv li, kev tiv thaiv cov xov hlau nrog qhov kub siab dua 500 degrees tsis yog welded ua ke nrog ib puag ncig kev siv .

Yuav ua li cas cov hlau tsis kam siv welded:

Ntswj ntawm ob lub taub hau ntawm ob cov xov hlau ruaj khov nrog txhua lwm, thiab tom qab ntawd siv cov nplaim taws rau ob lub taub hau me me .

Yog li ntawd, qhov teeb meem vuam ntawm cov hlau uas muaj zog tau txiav txim siab raws li qhov chaw ib puag ncig .
