Integrated computational materials engineering (ICME) is an emerging discipline that can accelerate product development and unify design and manufacturing. This paper summarizes the ICME applications for optimizing welding and thermal-forming processes. In the first application, numerical analyses were conducted to control weld distortion by using intermittent welding to replace full-length double-sided fillet welds and adapting new low heat-input processes such as the hybrid laser-arc welding process. In the second application, an existing software tool was validated and applied to automate thermal plate forming, a process which has been extensively used in the shipbuilding industry to form curved plates for several decades.
