The specialized book "Hot Cracking Phenomena in Welds II" offers a comprehensive analysis of the challenges and solutions related to the phenomenon of hot cracking in welds. It addresses the causes and mechanisms that can lead to crack formation during the welding process and highlights the importance of modern weldability studies. These studies take into account the interactions between base and filler materials, structural design, and the welding process itself. The book is based on the findings of an international workshop organized by leading institutions in Germany and provides a platform for the exchange of knowledge and experiences in this important field. The collected contributions come from experts from various countries and cover topics such as metallurgy, modeling, simulations, as well as testing and standardization procedures. This work is aimed not only at professionals in welding technology but also at anyone concerned with the safety and reliability of welded components.
