Welding simulations of the nickel-based superalloy Alloy 718 have been performed, combined with two fundamentally different hot crack indicators. The purpose of the indicators was to evaluate the risk of hot crack development in the weld. The result of the simulations has been compared with experiments. Advantages and limitations of the two hot crack indicators are discussed. Regions with a high value of the indicators in the simulations agree well with regions with hot cracks in the experiments.
