| description | This paper presents the first extensive research on secondary hazards and welding quality of a nover explosive welding technique, where colloidal water is used to cover the upper surfaces of the explosives. The use of the colloid water is proposed for improvement of energy efficiency and reduction of pollution of noise and dust. Welding tests were carried out to consider the effects of covering thickness on impact velocity of flyer plate, microstructure of bonding interface, explosion noise and dust. The results show that the colloid water significantly improves the ability of the explosive to drive the flyer plate, and reduce environmental pollution caused by explosion. The noise and dust decrease exponentially with increasing covering thickness, due to part of the shock energy and dust being absorbed by the colloidal water. Microstructure studies show that all the welds display wavy interfaces, and the wavelength and amplitude first increase and then decrease with increasing covering thickness. Vortices characterized by localized melting zone surrounded by strongly deformed bulk materials are formed for the welds performed with covering, and the EDS results indicate that the distribution of elements in the vortex region is gradually varied.
