Advanced Laser Spot and Plug Welding Utilizing Pattern Recognition and 6D Seam Detection
Remote laser welding has been applied in many industries for welding a broad range of materials. The ability to handle part-to-part variations can be challenging in light of the need for tight component tolerances. In this case, the focus of this paper will be around advancements in laser pattern welding utilizing integrated shape recognition and beam positioning to create spot and plug welds 3x faster than traditional resistance welding. This system utilizes a number of technologies for managing the adaptive process inclusive of integrated high-resolution camera coaxial to the beam that identifies shape and automatically positions beam with 20µm accuracy, a dark field illumination algorithm that eliminates extrapolation errors from offline programming, and up to 1000 Hz scan frequencies providing extremely fast system response. This adaptive technology has various points of application in industry where high levels of accuracy and faster speeds are required.

Ensuring Laser Micro Welding Success in Manufacturing
Laser micro-welding is a manufacturing process that joins parts on a millimeter scale. The miniature size of the parts brings challenges to achieving consistency in welding quality and production success. This presentation will cover several key factors to consider in the process development, along with measurements of the laser micro-welding process before, during and after the weld.

Advantages of Remote Laser Welding Utilizing Seam Tracking and Gap Bridging
Remote laser beam welding is attracting increasing attention due to the high productivity and the high saving potential realized by decreased production times. Now this already attractive technology has grown to the next level by incorporating accurate beam positioning utilizing 6D seam tracking. This combination allows adaptive welding with ability to overcome gaps in the process without the use of an external wire filler. In addition, by adding oscillation to the laser beam, the process is now capable of overcoming hot cracks in thin aluminum sheets.
