Abstract

The main focus of research presented here is the influence of cooling time t8/5 on impact toughness of A516 Gr. 60 steel specimens. Experiments include simulation of heating and cooling during welding (thermal simulation) in order to achieve desired microstructures that would correspond to those obtained in actual welding. Specimens simulated in this manner are then subjected to impact testing, and obtained results are analysed in terms of total impact energy and its components in order to provide detailed insight into the behaviour of these specimens. By obtaining diagrams that show mutual dependence of force, time, energy and displacement (deflection), it is possible to determine how impact toughness is affected by cooling times. Hence, the research provides valuable input for the selection of welding parameters.
