  • Method for producing a node by welding with the same width for two welds
    Patent number: 9505083
    Abstract: The invention relates to a method for producing a node by welding at least one first stranded wire comprising individual wires to at least one second stranded wire comprising individual wires, the stranded wires being of different materials, in a compression chamber with adjustable height and width of an ultrasonic welding device, the width being adjusted by means of at least one lateral slide and the height by changing the distance between a sonotrode and a counter electrode of the ultrasonic welding device, the at least one first stranded wire being welded with a higher specific energy, under a higher pressure or with a greater ultrasonic vibration amplitude than the at least one second stranded.
