A method for determining a welding sequence including a plurality of welding operations is disclosed. The method includes steps of determining a population of welding sequences based on a set of user-generated constraints, and simulating welding for at least one welding sequence in the population of welding sequences to obtain a multi-objective dependent distortion model of the at least one welding sequence. The method further includes steps of comparing a merit value of the multi-objective dependent distortion model for the at least one welding sequence with one or more predetermined criteria, and outputting a set of welding sequences as potential welding sequences based on the comparison between the merit value and the multi-objective dependent distortion model.

Method and system for determing welding process parameters

A system for determining a welding sequence is disclosed. The system may have a welding sequence generator configured to create an initial population of welding sequences based on a user-generated constraint. The system may also have a welding simulator configured to simulate welding for at least one welding sequence in the initial population of welding sequences to model distortion for the at least one welding sequence. The welding sequence generator may be further configured to receive the distortion for the at least one welding sequence in the initial population from the welding simulator, determine whether a merit value derived from at least the distortion for the at least one welding sequence satisfies one or more predetermined criteria, output the at least one welding sequence as a potential welding sequence if the merit value satisfies the predetermined criteria.
