Abstract: A system for impact welding using an electrical coil producing a magnetic field of sufficiently high-intensity to impel a ballistic workpiece into a separate stationary workpiece for producing a weld therein. The pressure on the ballistic workpiece resulting from the magnetic repulsion between the ballistic workpiece and the coil results in the ballistic workpiece being propelled towards the stationary workpiece at sufficient velocity to form a weld. Parameters are provided for varying the voltage and inductance of the capacitor bank for particular driving coil and ballistic workpiece dimensions to obtain matching of the impedances of the capacitor and coil arrangement to the particular ballistic workpiece. The impedance matching maximizes the conversion of electrical energy in the bank to kinetic energy of the workpiece.

Abstract: A system and method using magnetic pressure to propel a ballistic workpiece onto a stationary workpiece at sufficient velocity to produce a weld. Electrical power capacitors are connected to an electromagnetic coil which is positioned adjacent a ballistic workpiece which is propelled by pressures of magnetic force between the ballistic workpiece and the coil onto the adjacent stationary workpiece at sufficient velocity to form a weld.
