Abstract
The
essence, peculiarities and application fields of a new technology of explosion
treatment of welded joints used to improve reliability and extend life of
metal structures are outlined. Physical mechanism of the process and methods
used for calculation of parameters of explosion loading of different-geometry
weldments are described. Explosion treatment is shown to have a favourable
effect on performance of welded structures and characterized by high productivity
and cost effectiveness.
Keywords: welded joint, explosion treatment, explosive, reliability, corrosion resistance, fatigue, embrittlement, ecology of explosion
