Explosive welding (cladding):

  • Explosive welding (cladding):

  • steel (base) plates are placed

  • on the worktable.

  • Plates are made from low

  • carbon steel sheet by cutting,

  • milling and grinding.



Explosive welding (cladding):

  • Explosive welding (cladding):

  • - antifriction alloy plates (flyer

  • plates) are placed over steel

  • plates with a certain air-gap;

  • - explosive charge is placed

  • onto flyer plates.



Explosive welding (cladding):

  • Explosive welding (cladding):

  • bimetal plates after explosion.





Half-finished item has a

  • Half-finished item has a

  • semi-ring shape.

  • Commercially produced

  • products have steel layer

  • thickness in the range

  • from 3 to 20 mm, and

  • antifriction layer thickness

  • 2.0 – 2.2 mm. Semi-ring

  • diameter varies from 90 to

  • 260 mm.



















Use of Emulsion Explosive, containing hollow microballoons, makes it possible to decrease substantially the explosive charge and flyer plate mass;

  • Use of Emulsion Explosive, containing hollow microballoons, makes it possible to decrease substantially the explosive charge and flyer plate mass;

  • Use of reduced explosive charge permits to diminish residual deformations in manufactured workpiece. Residual stresses were not measured, but they evidently are diminished as well;

  • Development of new technology based on use of Emulsion Explosive will result in cutting of production costs.
