摘要： The invention relates to a method for laser welding a workpiece (1) along a welding line (20). A laser beam (13) is guided along the welding line (20) by moving an optical deflector unit (17). High movement speeds can be obtained using only a limited amount of machinery. The invention is particularly suitable for welding closure pins and casting induced openings (7) of gas turbine blades (1).
