N1 - Funding information: The authors sincerely thank the German Ministry for the Environment, Nature Conservation and Reactor Safety for their financial support for executing the project „OPTIWELD - Oekologische und oekonomische Hochleistungsfuegetechniken für Stahlrohrtuerme von Windenergieanlagen“ and the Institute of Materials’ Science Leibniz Universitaet Hannover, SIAG Tube & Tower GmbH and Kjellberg Finsterwalde Schweißtechnik Verschleißschutzsystem GmbH for their excellent cooperation.. New high-performance welding techniques are needed to weld thick plates faster and within fewer passes. Thus, the development of alternative welding technologies for fast and cost-effective welding of thick plates is of growing interest. The mechanical properties of welded components like hardness, ductility, ultimate and fatigue resistance are strongly influenced by welding. This is especially true for dynamically loaded structures where welds are the failure critical details of the total structure. Beam and hybrid welding reduce the local heat input which results in low cooling down rates. This is on the one hand positive for the development of welding distortion but negative for the residual stress state and metallurgical processes. Thus, welded components can be regarded from two perspectives: one perspective is the welding practice for producing repeatable and economical welds, and the other is design requirements concerning the mechanical properties of welds. Recently completed research work within the project OPTIWELD funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety deals with the question, how alternative welding techniques can be applied for welding thick plates and how the mechanical properties are influenced, both positively and negatively.
