Abstract EN
n this work, the diode laser (810μm wavelength) was used for laser transmission welding application on PMMA (polymethylmethacrylate).
The welding was done between opaqueness and transparent with thickness 2 mm and 2.57 mm, respectively.
The effects of different process parameters, laser speed, spot size and force with different values (5, 15, 20 mm/min), (2, 2.5, 3mm) and (2, 6, 10 N) respectively were used to study their effect on weld width and strength.
L9 Taguchi orthogonal array has been used to design the experiments and optimize the result.
The result of the signal to noise ratio shows that, the width of welding decrease with increasing both the welding speed and the spot size while it was increased with increasing the force on the sample.
The narrower width observed at speed (20mm/min), spot size (3mm), and force (2N).
Also, the best strength was found at speed (15 mm/min), spot size (2.5mm), and force.
