Core Technologies

The company has a large area multi-point synchronous initiation, detonation velocity control, edge discrete constraint and other explosive composite welding technology, breaking through the key technologies such as time-space distribution model of detonation velocity, unequal thickness distribution of explosives, linear wave initiation, multi-layer residual stress control, and so on. Compared with the existing domestic technology, the maximum blasting area of a single block increased by more than 120%. The defect area at the edge of the plate is greatly reduced to 5~10mm, which improves the yield of metal explosive composite manufacturing. With multi-layer single explosion welding technology, explosive welding energy balance technology and other independent research and development technology, 35 patents were applied, including 11 patents authorized.
 

Technical Team

  

The company has built Jiangsu Province Explosive Welding Engineering Technology Research Center and Jiangsu Academician Workstation, Jiangsu Province Research Workstation three major scientific and technological platforms, is a member of China Engineering Blasting Association.
 

Team members: a total of 16, including 1 academicians, 4 PhD students, 2 postgraduates and 8 undergraduates.
 

Innovative achievements: 57 patents were applied for, 11 of which were authorized to invent; participated in the compilation of National Standard of Explosive Welding Clad  Plate for Pressure Vessels (Standard No. NB/T47002.1-NB/T47002.4-2009); participated in the compilation of the authoritative reference book of the industry Blasting Manual; published 13 papers.
 

It has 3 high-tech products, 2 state-level Torch projects, 3 provincial and above science and technology awards, 1 Municipal Science and technology awards, and the "non-ferrous metal explosive welding composite material" has been awarded Nanjing famous brand products.
