Abstract

The aim of this work is to develop a model to simulate the high frequency (HF) welding process for cladded pipes and to find process parameters to solve the inconvenient power proportion between the cladding layers. A 2D model of HF pipe or profile welding was created. This model considers the most important parameters of the longitudinal HF-welding process of thin walled cladded pipes. Effects of welding speed, current frequency and material properties have been examined. The material combination of the metal sheets contains S235 as the carrier material and the corrosion resistant alloy 625 for the inner tube cladding. The results have been compared to an available experiment and to gain the basic validation of the model. An approach is proposed to facilitate high frequency welding of cladded pipes under consideration of industrial requirements for a chosen material combination.
