    The analysis of experience of lead through of local conflicts and special operations revealed, that considerable censures are in relation to reliability of the armored structures in part of firmness to the defeat of the weld-fabricated connections, and the searches of decisions require active in relation to the improvement of technological efficiency of processes of making of the armored constructions a welding method, and especially choice of rational method, taking into account the technical and economic features of concrete enterprise, and his introductions. Thus, the purpose of the paper is the exposition of the scientifically of the methodical vehicle from the ground of choice of the rational technological process of welding the armored structures, which is determined, in particular, by the choice of method that provides the most firmness to the action of striking factors and their longevity at the least charges on their making. As a result of analysis of existent scientifically-methodical vehicle from the ground of choice of method of the mechanized welding of the armored constructions and their rational mode perspective direction of management is certain by the transfer of electrode metal in the process of the mechanized welding by the modulated current, namely welding by powder-like wire with his irregular serve, that gives an opportunity of receipt of quality layer of metal, and also reduction of temperature influence on a parent metal. On the basis of the stated, the sequence of calculation determination of the rational mode of the mechanized welding offers the modulated current, coming from the necessary indexes of welding connection, set as the defined values or having a special purpose orientation with the use of mathematical models, that represent dependences of indexes on the parameters of the mode. The technical recommendations, that is directed on an increase efficiency of rational choice method of welding of the armored constructions worked out organizationally, taking into account technological and economic features, give an opportunity to improve technological efficiency of processes making the armored constructions with a method welding, that will allow to get for subdivisions MIA of Ukraine transport vehicles, able to provide more reliable protection of life of the personnel, to perform tasks in the East of our state, in future.
