5. Conclusion
The overall weldability of steels is not simply a choice of process: it is the result of an integrated approach, combining meticulous preparation, control of thermal parameters and knowledge of metallurgical behavior. By identifying and anticipating the risks of cracking, fatigue or deformation, professionals can considerably improve the quality of welded assemblies. Particular attention to joint design, chemical composition and post-weld treatments helps optimize the long-term performance of steel structures.
