DT3-SS2005: Welding of metals Prof. Dr.-Ing. P. J. Mauk Universität Duisburg-Essen Institut für Angewandte Materialtechnik Umformtechnik Welding of Metals Welding is the most important manufacturing process for joining machine elements. Joining methods in mechanical engineering: - Fasteners: screws and nuts not applicable in any cases very costly limits for big parts and very small parts - Riveting nowadays obsolete, very labour intensive costly application is limited difficult for automation - Welding: arc welding or resistance welding wide range for application useful for high strength application extremely flexible for different designs reliable, cost effective suitable even for extremely big parts state of the art joining process in technology Different types of welding: acc. to DIN1910 ( for details see copies of lecture books) - Fusion welding (Schmelzschweißen) electric arc welding (by electric current) gas (flame) welding ( C H Acetylen welding) 2 2 high energy beam welding (laser) - resistance welding ( Widerstandsschweißen) / - pressure welding (Press-Schweißen) - friction welding (Reibschweißen) Welding_of_Metals_beuke.doc ; Erstelldatum 28.04.2005 9:04 Seite 1 von 26 DT3-SS2005: Welding of metals Prof
