Explosive Mixture for Explosive Welding of Thin Foils
Propellants, Explosives, Pyrotechnics, 2010AbstractAn explosive mixture of PETN and baking soda has been investigated. It was found that the size of the PETN particles had crucial influence on the detonation properties of these explosives. The suggested mix of explosives can be recommended for use in explosive welding.

Welding is a process for joining metals by local coalescence or union across an interface. The essential conditions for any form of welding are that the two surfaces prior to welding should be absolutely clean and uncontaminated, and that these surfaces should be brought into contact.

Fundamentals, of explosive welding
Contemporary Physics, 1968Summary An account is given of the basic mechanism of adhesion in all welding processes, and a brief review of fusion and pressure welding techniques is given. A completely new method of welding which employs high explosives is briefly described and explained in terms of the principle used in the hollow charge, which wm developed during days of war to ...

Number of researches in the field of creating new technologies with impulse tension, have shown that explosion energy can be used in the following processes: processing by deformation (tin-sheet shaping) making holes, volume shaping, clinching, calibrating, surface hardening, sintering, under pressure casting, cleaning the castings, mounting, etc.

The methods of manufacture of welded composites fall into two main categories, depending on whether the geometry of the system is planar or tubular. A further sub-division occurs with the tubular components which can be produced either in axi- or asymmetric systems.

Design for quality explosive welding
Journal of Materials Processing Technology, 1992Abstract Mechanism and requirements of explosive welding, types of weld interfaces, influence of the interface type on the weld strength, causes of weld defects and the influence of various weld parameters on the quality are discussed. A need based design approach is suggested for achieving quality explosive welding. Through a number of illustrations,

Explosive Welding and Cladding
AIP Conference Proceedings, 2004Explosive welding or cladding is usually performed on relative thick plates by means of a large scale parallel plate set‐up. At TNO‐PML several of the explosive welding configurations that were developed mainly in the nineteen sixties and seventies are being investigated for their potential use in modern industrial applications.

In this study physical mechanism of explosive welding joint was analysed. The mechanism refers to wavy joint with interpass and without one. Plastic strain, viscosity and acoustic waves were applied to explain the problem. The own model of the mechanism of oxide removal for the direct joint and test results confirming the bonding mechanism were showed.

Wave Forming Mechanisms in Explosive Welding
Materials Science Forum, 2004Experimental results of wavy metal interfaces obtained by explosive welding are presented and used to determine which wave forming mechanism occurred. It was found that for small collision angles (smaller than about 20°) the Von Karman or jet indentation mechanism occurs, while for large collision angles a straight metal interface is obtained. However,
