Solid-state welding is a group of welding processes that produce sound joints at temperatures essentially below the melting point of the parent materials or without bulk melting of the parent materials. The joints produced by solid-state processes are usually free of various solidification defects such as gas porosity, hot cracking, and non-metallic inclusions, which may otherwise be present during fusion welding processes. No filler metals, flux, or shielding gas is required during solid-state welding process. The metal being joined can have mechanical properties similar to or even better than that of their parent metals due to the absence of defects and heat-affected zone in most of these processes. Unlike various fusion welding processes which are well known, solid-state welding is usually not well acquainted by industrial engineers. The purpose of this research is to determine the effect of various weld and machine parameters on ultrasonic weld strength. In this we are going to use thermosetting material named epoxy which is one of the low density polymers. By considering three main parameters that is amplitude, pressure and weld time we are going to conduct the experiment.
