Observation on Molton Slag of Welding
It is a very valuable subject to study how at ease we can weld or operate with a specific welding electrode, and there may be many different opinions as to the factors of "USABILITY" of welding electrode, if we so call it.We have tried to clarify such factors of "usability" of welding electrode, though with difficulties, and according to our ...

The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...

Electro-slag-Welding of Cr-Mo Steels
Seeing the macro-structure of electro-slag welded Cr-Mo steels, its grain size is finer as compared with ASTM A 302 B. This is because the plate thickness of Cr-Mo steel is thinner and its cooling velocity is faster than ASTM A 302 B. grain growth of deposit-metal which is shortcoming of electro-slag welding becomes more remarkably in proportion to ...
