Ultrasonic welding is a mechanical system whereby high-recurrence ultrasonic acoustic vibrations are privately connected to workpieces being held together compelled to make a strong state weld. It is usually utilized for plastics, and particularly for joining disparate materials. The point of the undertaking is to examine the quality of weld when unique materials are welded together. The sort of weld will rely upon an on-hold time, weld time, weight, and recurrence. Materials utilized will be HDPE (High Density Polyethylene) and a blend of HDPE-LDPE which is termed as MDPE (Medium density polyethylene). Diverse materials have distinctive properties and thus making a joint with wanted properties will give a better outcome. If one material has properties like better elasticity, pressure quality and other material have properties like pliability and flexibility and so forth then the blend of these materials will have properties of both the materials and when these kinds of materials are welded ultrasonically, they give a better outcome. Subsequently we will get a material which will give better quality with ease. Likewise, the material will be increasingly adaptable.
