MIG Vuam Hlau Rau Stainless Hlau ER347 Cryogenic cia nkoj vuam cov ntaub ntawv
WELDING TECHNOLOGY
Tsis txhob cia cov lus nug
Txuas ntxiv mus haunt koj
Arc instability
Unsightly molding
Tshaj tawm ntau dhau
Feem ntau siv rau hauv cov khoom noj khoom haus, cov cuab yeej kho mob, cov hlab ntsha siab, petrochemical thiab lwm lub sijhawm xws li 1Cr19Ni11Nb (SUS347).
Vim qhov sib ntxiv ntawm Nb, cov hlau molten muaj qhov zoo
intergranular corrosion kuj thiab ruaj khov mechanical zog
Ripple zoo
Smooth hlau pub, ruaj khov arc, zoo nkauj sib sau
Zoo ntws ntawm molten hlau, tsawg txaws, thiab zoo heev vuam txheej txheem kev ua tau zoo.
