| titleOfInvention | FORGING PIPES |
| abstract | The method of forge welding of pipe ends, in which the ends of pipes are heated to a predetermined temperature above 1200 ° C and surrounded with non-oxidizing and / or reducing protective gas, while the ends of the pipes are pressed to each other, and the method provides for the cooling of the pipe ends welded by forging welding from the specified temperatures above 1200 to 600 ° C or lower for 3 minutes after the operation of forge welding. Separate inner rod 30, equipped with EMAT weld control sensors, heat treatment coil 23 and cooling medium nozzles 18, can be used to rapidly cool forged pipe ends 19 welded by forging, possibly together with outer ring 7A, 7B, which can also be equipped with pipe gripping, heating, cooling and / or EMAT weld monitoring tools. The international application was published with an international search report. |
