MUP2 - Resistance projection welding of complex welding of complex metal combinations and geometries

The aim of the present framework programme is through some basic, systematic process analyses to improve the basis for industrial optimization and development of the resistance projection welding for assembly of complex metal combinations and geometries. Objectives are:
* to establish of a profound basis of experience, making possible an evaluation and prediction of the weldability and weld quality when resistance projection welding complex metal combinations and geometries
* to analyze the importance of statistical variations in composition of alloy and in surface contamination when projection welding stainless steel
* to establish rules for selection of electrode material and to find substitute material for beryllium alloyed copper and to establish guidelines for electrode design and electrode cooling
* to develop procedures for characterization of the electrical and mechanical properties of resistance projection welding machines as regards selection of machine and welding parameters for a specific welding job and to facilitate maintenance of the machines
* to develop a numerical model for the analysis of resistance projection welding
