One of the biggest hurdles in any automated joining system is the ability to find and track the joint in a consistent nature. Joint quality can be poor due to a number of variables including the standard variance in upstream parts supply or simply poor joint design from either a process or product perspective. Firstly, there is the variation that is inherent in single parts and the overall stack up.
As material selections in automotive manufacturing move further into the high-strength realm, along with the more prevalent usage of difficult-to-weld materials such as aluminum, developing robust processes for joining these materials becomes ever more critical. Adaptation of technologies such as real-time seam tracking, gap bridging, beam oscillation, and integrated clamping to laser-related processes allows for them to be used in a more mainstream approach.
