Influence of nonmetallic inclusions on the resistance of metal weld to brittle fractures [PDF]
According to statistics, up to 80% of all fixed metal structure accidents are associated with welded joints. However, most of the emergency destructions, usually caused by non-metallic inclusions in the weld metal, are fragile. The probability of brittle

Reactions at the molten flux-weld pool interface in submerged arc welding
In submerged arc welding (SAW) of chromium (Cr) containing steels, Cr is usually added to the weld metal from the weld wire, and not from the welding flux.

New technology for production of granular adding material with nanomodifying additives for steel arc welding [PDF]
The chemical analysis of metal seam showed that introduction of titanium dioxide with MCA intensifies transition of Al2O3 from slag into metal pool and provides double concentration of titanium in the seam compared to the one which appears in the ...
