LASER WELDING SYSTEM CAPABLE OF PREVENTING FAULTS DUE TO WELDING FLAME BY PREVENTING THE GENERATION OF A LASER BEAM OVERLAPPED PART AND WELDING FAULT PART

摘要

PURPOSE: A laser welding system capable of prevention of fault due to welding flame is provided to prevent the generation of a welding fault part and laser beam overlapped part by simultaneously welding entire circumference of the welding part of a welding target.;CONSTITUTION: A laser welding system comprises a laser emitting part(110) and a lens part(120). The laser emitting part emits a laser beam for welding to a welding object(100). The lens part reflects a laser beam to the entire circumference of the welding part of the welding object. The lens part comprises a first lens part(130) and a second lens part(140). The first lens part reflects laser beam, from the laser emitting part, in a radial direction. The second lens part guides the laser beam, radiated from the first lens part, to the welding part of the welding object.;COPYRIGHT KIPO 2011
