In welding, the components are joined together by heat and/or force with or without filler metal. The creation of the joint can be made possible or even simplified by welding consumables, e.g. shielding gases, welding fluxes or pastes.
Taking into account the special physical and mechanical properties, many copper materials can be welded well. Depending on the material used, the appropriate manufacturing parameters such as welding processes, filler metals and pre- and post-treatments must be selected. Copper can form alloys with many different metals, so that a variety of alloy systems are available in which certain properties such as hardness, tensile strength, yield strength, chemical resistance, wear resistance and others can be specifically influenced. The welding processes used are just as varied as the copper materials. It is therefore not possible to simply conclude from the weldability of pure copper grades to the weldability of alloys such as brass or bronze. Even within the pure copper grades, different degrees of purity lead to different process adjustments during welding.
