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, khoom siv kho mob, cov hlab ntsha siab
Petrochemical thiab lwm lub sijhawm xws li 1Cr19Ni11Nb (SUS347).
Ripple zoo
Vim qhov sib ntxiv ntawm Nb, cov hlau tso tawm tau zoo
intergranular corrosion kuj thiab ruaj khov mechanical zog
ruaj khov arc, zoo nkauj sib sau, zoo ntws ntawm molten hlau, nrog zoo heev vuam txheej txheem kev ua tau zoo
Yooj yim slagging
