研究目的
Investigating the effects of welding speed, thickness, and welding line width and depth on the quality of laser transmission welding of PMMA polymer.
研究成果
The welding line width and depth were found to be inversely proportional to the welding speed, while the transparent slab thickness had little effect. The Taguchi method and grey relational analysis provided optimal welding parameters, showing good agreement with experimental results.
研究不足
The study is limited to PMMA polymer and does not explore other materials. The effects of other parameters like laser power and beam diameter were not varied.
1：Experimental Design and Method Selection:
The study used a semiconductor laser with 808 nm wavelength, 2 W output power, and a 2 mm beam diameter for welding PMMA polymer slabs. The Taguchi method and grey relational analysis were employed for optimization.
2：Sample Selection and Data Sources:
Three different transparent PMMA slabs with dimensions 40x60 mm and thicknesses of 2.6, 3.7, and 4.3 mm were used. The slabs were fixed onto an oblique slab (dark color).
3：6, 7, and 3 mm were used. The slabs were fixed onto an oblique slab (dark color).
List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: Semiconductor laser (808 nm, 2 W), PMMA slabs, optical microscope model Olympus BX51M-Japan, and an optical scanner.
4：Experimental Procedures and Operational Workflow:
Three different welding speeds (44, 113, 150 mm/min) were applied to each sample. The welding width and depth were measured post-welding.
5：Data Analysis Methods:
The Taguchi method and grey relational analysis were used to analyze the experimental data and determine the optimum welding parameters.
