METHOD OF PLATING Russian patent published in 2009 - IPC B23K20/08 

FIELD: metallurgy.

SUBSTANCE: invention can be used at manufacturing of metallic structures in metal working industry and chemical engineering and also at emergency repair of bottoms of large-size technology, restoration of disturbed leaktightness of large-size structures and other. Massive plate ingot is located by its flat surface over sheet of plating parallel to welding clearance. Coating sheet is located on high explosive. Itself explosive substance is located in cavity of rigid basis in the form of charges with different speed of detonation corresponding to constancy of deforming impulse n a zone of collision along the total connectable surface during the process of explosion welding. Then the high explosive charge is initiated. Specified correlation of values of deforming pulses is selected from condition of receiving of required rate of activation of contact surfaces for forming of reliable connection.

EFFECT: invention provides facilitates stabilisation of parametres of wave profile of welding seam along detonation front on total surface of connected zone and reduction of residual deflection of two-layer composite.
