Abstract: 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.

Abstract: A fixture member in contact with a work piece to detect a load caused by the work piece is disclosed. The fixture member includes a first layer and a second layer defining a first thickness and a second thickness, respectively. The second layer is disposed on the first layer. The second layer is further in contact with the work piece. The fixture member also includes a sensing device disposed between the first layer and the second layer. The sensing device is configured to generate a signal indicative of the load caused by the work piece.
