Arc welding / hard soldering process, for connecting of copper with a low heat input

摘要

An arc welding - / hard soldering process is disclosed, which is useful to provide a first piece of copper being and a second piece of copper being connected to one another, without a more heat-sensitive materials, which can be arranged in the vicinity of damaging. The arc welding - / hard soldering process comprises the use of a consumable electrode wire, the electrically with a weld controller in a negative polarity oriented communicates via a through an arc between a guide pointed end of the electrode wire and the first piece of copper being a gap formed. The current which flows through the arc, when the sheet is formed, the first piece of copper being heated, so that the first piece of copper being is connected with the second piece of copper being. The connection between the first piece of copper being and the second piece of copper being an autogenous welding connection or can be a hard-soldered joint.
