    Abstract: A method for making a joint between copper or copper alloys and austenitic steel alloys, in which method in between the junction surfaces of the objects to be joined together, there is arranged at least one intermediate layer, so that the junction surfaces in cluding their intermediate layers are pressed together, and at least the junction area is heated in order to create a diffusion joint. In the method, there is brought a first intermediate layer (3) on the junction surface of the steel object (2) or against said surface, mainly in order to prevent the nickel loss from the steel object (2), and at least a second intermediate layer (4) on the junction surface of the copper object (1) or against said surface in order to activate the creation of a diffusion joint.

    Abstract: A system and method of welding stainless steel to copper is provided. The method includes providing a first workpiece (WP1) composed of stainless steel and provid- ing a second workpiece (WP2) composed of copper. The method also includes heating by using a laser (110; 110') a root area of a joint created by the workpieces. The heating by the laser creates a keyhole in at least one of the first workpiece and the second workpiece. The method also includes providing a consumable electrode (140; 140') that is composed of nickel to the joint and creating an arc (112) between the consumable electrode and the joint using a welding current. The preheating of the arc using the keyhole eliminates the need to preheat the second workpiece.

    Abstract: A method for joining a highly electroconductive core part (2) to a jacket part of refined steel (1). In the method a highly electroconductive core part (2), such as a copper bar, and connection component (3) are placed inside a jacket (1) having poorer electroconductivity, and are heat treated at least where the join of the pieces to be connected is located, in such a way that a metallurgical bond is formed between the electroconductive core part (2) and the refined steel jacket.

    Abstract: A method for brazing an electrically conducting connecting piece, for example a cable shoe, of an electrically conducting material to a workpiece of electrically conducting material, by means of a temperature controlled brazing process in which the heat necessary for brazing is generated by striking an electric arc between a carbon electrode, and the electrically 5 conducting connecting piece, where the voltage and current is electronically controlled by control electronics to achieve a temperature development to result in a martensite free brazing, and wherein the DC voltage applied is using the carbon electrode as the negative pole, and using the electrically conducting connecting piece as the positive pole, and 0 wherein the carbon electrode is having a tapering, bevelled, or pointy end at the end facing the electric arc.
