According to estimations of specialists, a great number of structures, constructions and
machine in operation in Ukraine have exhausted their designed service life. In this
connection, of special current importance are the issues related to control of operating
reliability and durability of critical facilities by determining their technical state,
residual life and scientifically grounded safe operation life.
Below we give a selection of articles based on the results of studies completed in
2007—2009 under targeted integrated program RESOURCE of the National Academy
of Sciences of Ukraine by involving scientists and specialists from 26 institutions of
8 departments of the Academy.

SUBSTANTIATION OF THE SYSTEM
OF DEOXIDATION AND MICROALLOYING
OF DEPOSITED METAL WITH ELECTRODES
FOR WELDING AND REPAIR OF BRIDGE
AND TRANSPORT STRUCTURES

The paper provides substantiation of the system of deoxidation and microalloying of weld metal produced with electrodes
that are designed for welding and repair of bridge and transport structures. The main characteristics of the electrodes
developed by using this system are described.
Keywords: arc welding, structural low-alloy steels, covered
electrodes, welding and repair of structures, microalloying
system
The Second Pan-European Transport Conference held
in 1994 passed the program of development of the
continental transport network, according to which
nine main transcontinental cargo transportation directions,
called «Crete Corridors», were to be built.
Four of them are to pass through the territory of
Ukraine. Taking a central place in Europe in this way,
i.e. having the highest transit traffic factor among the
neighbouring European countries, Ukraine should become
a peculiar bridge between Europe and Asia to
substantially reduce traffic expenses and delivery time
in the system of international goods exchange. The
program was approved for building and functioning
of the national network of international transport corridors
in Ukraine [1].
To implement this program, it will be necessary to
upgrade railways, so that they meet modern requirements
for speed, length and weight of the passed-through
trains, build new highways of the international level,
construct many bridges, tunnels and crossroads, as well
as 26 unique transport-storehouse terminals.
Transport problems have to be solved also because
of the European Football Championship to be held in
2
Ukraine in 2012. City and belt highways are reconstructed
in Kiev and other cities of Ukraine. Bridges
across the Dnieper River, over- and underpasses, as
well as junctions at most intensive traffic crossroads
are built. This will require involvement of metalwork
and transport engineering factories, as well as building
and assembly organisations that intensively employ
welding technologies. For factory conditions, these
are mostly mechanised welding processes. However,
part of the operations, which are associated, as a rule,
with welding of the most critical structures and repair
of defects are traditionally performed under factory
conditions by using covered electrodes. In field, the
major part of spatial welds, which for technical reasons
cannot be made by the mechanised welding methods,
are usually produced by manual covered-electrode
arc welding.
Operation of bridge and transport structures,
which were built earlier, is accompanied by current
repairs and overhauls to maintain them in an appropriate
condition. After liquidation of the united national
economy system of the USSR, condition of basic
assets of the key industries and inter-industry manufacturing
infrastructure in Ukraine and other CIS
countries is constantly deteriorating.
