Ua ntej qhov ncaj seam steel yeeb nkab tsis raug kuaj, qhov kev tshuaj ntsuam xyuas ntawm qhov vuam yuav tsum ua tau raws li qhov yuav tsum tau ua. Lub vuam sib txuas rau cov hlua txuas feem ntau xav tau cov tsos thiab qhov zoo ntawm qhov ncaj vuam seams raws li hauv qab no:
Lub vuam zoo yuav tsum zoo, thiab qhov dav yuav tsum tau them los ntawm 2 hli ntawm ob sab ntawm lub ramp. Qhov siab ntawm qhov sib koom ua ke ntawm kaum vuam yuav tsum ua tau raws li cov kev cai tsim, thiab cov duab yuav tsum tau hloov mus kom du.
Vuam sib koom nto
(1) Tsis pub muaj kab nrib pleb, tsis muaj melting, residue, thiab txaws.
(2) Cov kav hlau hlau uas muaj qhov tsim kub qis dua -29 degrees, thiab qhov chaw vuam ntawm cov kav hlau tsis muaj steel hlau uas muaj qhov loj ntawm cov tawv tawv yuav tsis tom sab. Lub vuam tom ntawm lwm yam ntaub ntawv yuav tsum siab tshaj 0.5 hli. Qhov ntev ntawm qhov txuas ntxiv yuav tsum tsis txhob siv ntau tshaj 100 mm. Tag nrho qhov ntev ntawm qhov tom ntawm ob sab ntawm lub vuam yuav tsum tsis pub tshaj 10% ntawm tag nrho qhov ntev ntawm qhov vuam.
(3) Qhov saum npoo ntawm qhov vuam yuav tsum tsis txhob qis dua qhov chaw ntawm cov kav dej. High welding residual nyiaj tsis ntau tshaj 3 hli.
(4) Qhov tsis ncaj ncees lawm npoo ntawm cov vuam txuas yuav tsum tsis pub tshaj 10% ntawm phab ntsa tuab, thiab yuav tsum tsis pub tshaj 2 hli.
