Txoj kev txiav (automotive blanking)?
Laser / plasma / nplaim taws txiav yog txhua yam siv tau; laser rau nyias daim hlau (siab precision), nplaim taws/plasma rau tuab daim hlau.
17. Txias dabtsi yog khoov/stamping ceev faj?
S355MC: Khoov vojvoog Ntau dua lossis sib npaug rau 1.5t, kev ua haujlwm zoo sib sib zog nqus.
S355JR: Khoov vojvoog Ntau dua lossis sib npaug li 2t, tsis txhob muaj qhov nkhaus nkhaus.
18. Pom zoo txheej txheem vuam (automotive)?
CO₂ gas shielded vuam (mainstream).
Vuam hlau: ER50-6.
Tam sim no: 180-240A, dhau qhov ntsuas kub tsawg dua lossis sib npaug li 250 degree.
19. Tshaj tawm -weld cua sov yuav tsum tau kho?
Feem ntau tsis yog; rau cov phaj tuab / siab- qhov kev ntxhov siab, kev ntxhov siab- pom zoo kom tshem tawm qhov annealing ntawm 550-600 degree.
20. Kev kho deg (automotive corrosion tiv thaiv)?
Pickling → Phosphating → Electrophoresis / Txau; Pickled daim hlau qhia 30% + nce hauv txheej adhesion.
