Technological bases of industrial
technology
• Choice of the scheme of welding taking into account properties of welded
materials, features of deformation of narrow sides and scraps of an
overhang of a plating sheet;
• Rational technology of preparation of surfaces of initial materials and
assembly of packages;
• Use as explosive substances (ES) of mix of microporous ammonium nitrate
with diesel fuel;
• Minimizing of influence of external factors due to performance of all
operations on preparation for welding by explosion in shop and only an
apportion of a charge of ES and its blasting on an explosive platform
• Quality control at all stages of production of bimetal;
Influence of a tamping and way of preparation of the low-speed
