Beschreibung
Zusammenfassung:	The invention relates to a gastight connection between tubes of small diameter of metals or metal alloys having different melting points, more particularly copper and aluminium, wherein the end zone of the first tube (1) is opened out and the second tube (2) of a lower-melting material is inserted and soldered into the opened-out portion (3), the internal generated surface or the opened-out portion (3) merging via an internal cone (4) and an extension (38) into that zone of the first tube (1) which is not opened out, a sleeve (34) of special steel possibly being inserted in the end zone or the second tube (2). (The is based on Fig. 4.)
