Peer-Reviewed Section


Realization and safe operation of modern welded structures are progressively requiring for base and filler materials to cope with continually increasing loads, Analyses with a view to crack prevention therefore need to accommodate particularly the structural design (restraint intensity) and the thermomechanical effects in terms of stresses introduced during welding, Against this background, multi-run welding experiments were carried out in an IRC - (Instrumented Restraint Cracking) Test under defined restraint intensity in order to examine the influence of heat control (preheating and interpass temperatures) on the weldinq-specific forces and stresses, The experiments revealed significant rises in the reaction force and stress after welding with increasing preheating and interpass temperature, Furthermore, various concepts for calculating the preheating temperature are discussed, It is demonstrated that the hitherto existing concepts for high-strength finegrained structural steels can lead to divergent results.
