Abstract

The subproject B5 examines the welding technological processing of locally hardened materials to produce structures and knots by means of high-freqency welding (HFW). The aim of B5 is a defined intervention in process and plant technology to control current voltage, temperature and compressive stress distribution of the entire weld seam. Particularly the effects on locally hardened areas have to be measured and optimized. Also the process specific advantages of HFW (e.g. plastic deformations and the application of an in situ heat treatment) have to be examined and optimized to improve structural strength.
