A power electronic arrangement has a power converter module including a switching device with a substrate with a first and a second DC voltage conductor track and a first and a second DC voltage terminal element connected in an electrically conducting manner with the correct polarity, and has a first and a second DC voltage connection element. The first DC voltage terminal element is connected to the first DC voltage connection element in an electrically conducting manner with the correct polarity by means of a first materially-bonded connection. The second DC voltage terminal element is connected to the second DC voltage connection element in an electrically conducting manner with the correct polarity by means of a second materially-bonded connection. The second DC voltage terminal element or the second DC voltage connection element has a continuous welding cavity in the region of the first connection.
