Web10 apr. 2024 · Laser welding can be automated through robots, creating clean welds that require little to no post-weld processing. LBW equipment is initially expensive and the process isn’t suitable for plastics with thicknesses above 0.5 inches (12.7 mm). Laser beam welding can sometimes lead to porosity and brittle results. WebA laser’s beam diameter characterizes the transverse extension of the beam, or its physical size perpendicular to the direction of propagation. It is often defined at the 1/e 2 width, which is bounded by the points where the beam’s intensity reaches 1/e 2 (≈ 13.5%) of its maximum value.
