METHOD FOR PRODUCING A WELDED JOINT AND CREATING AN IMAGE OF THE WELDED JOINT BY MEANS OF COOLED X RAY TUBES

摘要

The invention relates to a method for producing a welded joint (8) having the steps of: providing an x ray tube (3) arranged within an x ray housing (5) for generating x- ray radiation and a detector (4) arranged within a detector housing (6) for receiving the x ray radiation; flowing a cooling medium through the housing (5, 6); heating components (1 , 2) to be welded to the pre heating temperature required for producing the welded joint (8); welding the welded joint (8); creating an exposure of the welded joint (8) by means of the x ray tubes (3) and the detector (4) at a temperature of the components (1 , 2) which is essentially the pre -heating temperature or higher wherein the cooling medium flows through the housing (5, 6) such that the x ray tubes (3) and the detector (4) operate at the respective operating temperatures thereof.
