electroslag welding

[i′lekṁtrō‚slag ′weldṁiŋ]
(metallurgy)
A welding process in which consumable electrodes are fed into a joint containing flux; the current melts the flux, and the flux in turn melts the faces of the joint and the electrodes, allowing the weld metal to form a continuously cast ingot between the joint faces.

electroslag welding

A welding process in which the two surfaces to be welded are fused together by use of an electrically liquefied molten slag which melts both the filler metal and the two surfaces.

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].
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.
