Abstract
Przedmiotem wynalazku jest metoda orbitalnego spawania z kontrolą jakości za pomocą kamery termowizyjnej w szczególności stosowana przy spawaniu orbitalnym rur oraz urządzenie do orbitalnego spawania zintegrowane z kamerą termowizyjną do spawania rur. Sposób orbitalnego spawania charakteryzuje się tym, że obszar spawania obserwowany jest za pomocą kamery termowizyjnej (1) skierowanej na rejon znajdujący się za jeziorkiem spawalniczym i obejmujący obszar zakrzepniętej spoiny i w przypadku zmiany temperatury stygnięcia spoiny, jeżeli spadek temperatury będzie większy co najmniej o 5% korygowane są parametry spawania w ten sposób, że poziom energii liniowej spawania ściegu drugiego i ściegów wypełniających zawiera się w granicach 0,8 - 1,8 kJ/mm, a trzech ściegów lica spoiny zawiera się na poziomie 0,75 - 1,7 kJ/mm, przy czym istotne są różnice poziomu temperatury w tej samej odległości od jeziorka spawalniczego i w trakcie stygnięcia spoiny.The subject of the invention is the orbital welding method with quality control by means of a thermal imaging camera, in particular used in orbital welding of pipes and an orbital welding device integrated with a thermal imaging camera for welding pipes. The orbital welding method is characterized by the fact that the welding area is observed by means of a thermal imaging camera (1) directed to the area behind the weld pool and covering the area of solidified weld and in the event of a change in the weld's cooling temperature, if the temperature drop is corrected by at least 5% there are welding parameters in such a way that the level of linear energy for welding the second stitch and filling stitches is within the range of 0.8 - 1.8 kJ / mm, and the three stitches of the weld face are between 0.75 - 1.7 kJ / mm, but the differences in temperature level are the same distance from the weld pool and when the weld cools down.
