A method of explosive welding of alumnium alloy to steel

摘要

The invention relates to a method for explosive welding of Aluminium alloy to steel, comprising of placing a flyer plate having a reverse side and an obverse side, made of Aluminium alloy at a pre-determined standoff distance from the surface of a base plate made of steel with obverse side of the flyer plate facing the base plate, the flyer plate having a proximal and a distal end; placing explosive composition comprising trimonite and common salt on at least a portion of a surface of the reverse side of flyer plate; and initiating detonation of the explosive composition on the proximal end, thereby causing a detonation to travel towards the distal end, thereby generating a jet to clean the obverse side surface of the flyer plate and the surface of the base plate and generating adequate kinetic energy for flyer plate to weld with the base plate.
