Welding defects have to be suppressed to maintain the mechanical strength of a product under load. For suitable choice of the process parameters operating windows can be entered where a certain welding defect can be suppressed. However, the identification of such operating windows is empirical and moreover difficult to transfer, as the process depends on 20-30 parameters and each industrial application used to be a different, thus new situation.
