• wherein
• aluminium having a purity of at least 99 weight percent is used for the connection,
• the connection is heated beyond its melting point and melted onto the first body part,
• the connection being purified from oxide components before melting it onto the first body part, and
• the opening of the first body part being closed by the connection.
