Introduction  \nWelded joints on copper and copper alloys are characterized by their excellent reliability and reproducibility in terms of process technology, and by low transition resistance in terms of materialsproperties. Welding is therefore one of the most frequently used joining technologies for copper and copper alloys, along with mechanical jointing and soldering.  \nIn the electrical engineering/electronics sector, components made of strip materials are mostly jointed by welding joined using the two well established processes, resistance welding or laser beam welding. Besides that, ultrasonic welding is becoming increasingly important. Electron beam welding and gas-shielded welding are also used for copper and copper alloys, although less frequently.  \nIn principle, all pure copper grades and all copper alloys can be welded by any process . The decisive factor is the selection and setting of the parameters on the welding machines. The frequently heard statement that copper is poorly weldable or not suitable for welding is based on the different nature of copper materials compared to what welding personnel and engineers are used to from ferrous materials. As an example, copper dissipates welding heat much faster than steel does. Copper also has a much higher reflectivity to IR radiation, which makes it more difficult to couple laser radiation. It is therefore the task of copper processors to take these special properties into account when setting the welding parameters.  \nIn recent decades, research and development in institutes and in the copper-processing industry have worked intensively on the task of generating welding knowledge about copper and making the various welding processes available for copper materials to users as an easy-to-handle industrial process.  \nThis brochure provides information and a guideline how to weld Wieland strip made of copper and copper alloys, referring to the most common welding processes. It is intended as a supplement to the relevant technical literature.  \n2. Weldability – a complex subject  \nWelding represents a group of joining techniques, producing inseparable metallurgical bond connections of components by applying heat and/or pressure, with or without filler metals.  \nThe weldability of a component is largely dependent on the three influencing factors which are material, design and manufacturing process. These parameters interact in complex ways. Thus, the material alone should not bethe only factor to be evaluated when assessing welding issues. Instead, a holistic view of the complete welded construction isnecessary, including its periphery, such as clamping devices and neighboring assemblies, as well as the component design.  \nAccording to Fig. 1, the term suitability for welding describes a pure material property.  \nIt ","cbCaiszwji1Ri39t","https://ap.wps.com/l/cbCaiszwji1Ri39t","pdf",861547,32,"English","# 1.
