An electro-welding sleeve (A) with a heating component (3) is equipped with an input-output medium (4) for identifying pertinent production and welding data. This input-output medium works bidirectionally, and so the data generated when sleeve (A) is positioned, such as actual welding parameters, working site and ambient temperature, can be stored in the input-output medium (4) of the welding sleeve after the welding process. The sleeve can thus be unmistakably identified at any time. |
