TY - GEN A1 - Kannengießer, Thomas T1 - Key aspects of component welding applying higher-strength fine-grained structural steels N2 - The increased application of higher-strength steels and filler materials necessitates a more profound understanding of the interactions between the welding process, the heat input, the cooling conditions and the resulting metallurgical processes in the weid and its surroundings. Strategies, which help to improve the strength properties and life-time of welded stmctures to such an extent that the utilisation of higher-strength materials can be justified and their lightweight construction potential can thus be exploited to the füll, can only be derived from the interaction between all the influencing factors. Examples of a few investigations on welded joints between higher-strength fine-grained structural steels with regard to the interactions between the main variables influencing the cold cracking are presented in this article.
