Radiographic Geometry
Beam geometry describes the position and direction of the laser relative to the workpiece. Optimal geometry increases weld quality and productivity.
Physical-Chemical Mechanism
Beam geometry refers to the position and orientation of the laser relative to the workpiece. Correct geometry ensures that the laser energy uniformly covers the material surface, leading to optimal weld pool formation.
Metallurgical Relevance & Welding Risks
Suboptimal beam geometry can cause uneven weld pools and irregular weld profiles. This increases the risk of cracks, distortion, and reduces weld strength.
Workshop Practice & Operating Instructions
To ensure optimal beam geometry, position the laser so it strikes the material surface perpendicularly. The distance between the laser and workpiece and the laser's pivot range must be precisely set. Recommended values vary by material and welding process, but typically the optimal distance is 50 to 100 mm.
