The primary objective of this program was to demonstrate that the Oregon Graduate Institute-developed electroslag welding
technology can be successfully implemented in commercial fabrication shops.
At the same time, this was not detected in electroslag welding.
4 m/h) was used in electroslag welding of large blanks with the area of the welded section of several square metres [11, 13].
The main difference between the structure of the metal in the weld zone in ECMO of 40Kh steel in comparison with that in electroslag welding of the alloyed medium carbon steels is the considerably larger grain size in the metal of the high-temperature section of the heat affected zone.
In case of continuous supply of the molten metal into the cladding area and uniform movement of the heat release source relative the surface being clad penetration of the base metal is mainly of rectilinear character detected, for example, in welds, produced by the electroslag welding, using a consumable electrode under stationary conditions of melting.
So, in contrast to the classical process of electroslag welding, distribution of current in the slag pool of the current-conducting mould enables formation on the slag--metal boundary of the concentrated source of heating, whereby a certain role in formation of the fusion line play size and frequency of the molten additive metal feeding.
