Abstract
The present work discusses about the introduction of silver interlayers in dissimilar friction welding process. The characteristics of silver interlayer influenced friction weld are compared with the silver free dissimilar friction welding process. Particle fracture occurs commonly in welding process. It leads to poor quality of welds and decreases the strength of the weld which creates brittleness. Friction welding process itself reduces the particle fracture but for more precise and reliable welds, silver interlayer can be used. The introduction of silver interlayer not only reduces the particle fracture but also reduces average particle radius and leaves the particle volume fraction unchanged. So the friction welding process with silver interlayer produces more efficient welds. From all the considerations it is concluded that stable strong and friction welds with less particle fracture can be produced by the influence of silver interlayer in dissimilar friction welding.
