Mechanical Properties and Other Characteristics of Ultrasonic Welded Joints in Absorbers of Solar Panels in Respect of Performance Requirements

Krzysztof Kudła, Kwiryn Wojsyk, Marek Gucwa

The study presents the geometry as well as results of the peeling, shearing and metallographic tests of copper and aluminium welded joints used in the absorber panels of flat solar collectors. The article discusses desired characteristics and mechanical properties of ultrasonic welded joints and compares the latter with laser welded joints. In addition, the study indicates prospective implementation areas of ultrasonic welding technologies.
