Abstract

Sposób spawania stali ulepszanych cieplnie charakteryzuje się tym, że podczas spawania prowadzi się bezpośredni, szybki i precyzyjny proces obróbki cieplnej spawanego złącza prowadzący do hartowania i wywołania procesów samoodpuszczania wskutek działania ciepła skumulowanego w materiale i chłodzenia mikrostrumieniami, przy czym w trakcie procesu na bieżąco prowadzi się numeryczną analizę rozkładu temperatury, monitorowanie i regulację intensywności chłodzenia w strefach wpływu ciepła.The method of welding toughened steels is characterized by the fact that during welding, a direct, quick and precise process of heat treatment of the welded joint is carried out, leading to hardening and self-tempering processes due to the action of heat accumulated in the material and cooling with micro-jets, while the process is carried out on an ongoing basis numerical analysis of temperature distribution, monitoring and control of cooling intensity in heat affected zones.
