Influence of welding parameters on mechanical properties of welded joint at capacity discharge welding process
Capacity discharge percussion welding is nonconventional welding process where heat source is an electric arc obtained by discharging of capacitor bank. The arching time is very short, around 10 ms, and depends on a few parameters such as: capacity of capacitor bank, voltage, movement speed of welded pieces during welding. During arching a certain amount of material is melted and after that squeezed out by applied force used in welding process. Quantity of squeezed material depends upon heat input, intensity of the force pressing the wires during welding and many other parameters. Mechanical properties of welded joints depend on welding parameters. In this paper is described the influence of capacity discharge percussion welding parameters on mechanical properties of welded joints.
