研究目的
Investigating the welding characteristics of butt-welded Inconel625 plate using CO2 laser beam, focusing on distortion, bead geometry, and weld quality.
研究成果
The CO2 laser beam welding procedure is effective for Inconel625, producing defect-free welds with lower distortion at lower heat inputs. The study identifies optimal process parameters for welding Inconel625 plates.
研究不足
The weldments are not fully penetration in all the trails due to the increase in welding speed. Variance in the weld bead geometry was observed in both the combinations.
1：Experimental Design and Method Selection:
The study uses CO2 Laser beam welding process on Inconel625 plates with varying laser power and welding speed. L4 orthogonal array is chosen for experimentation to minimize the effect of noise factors.
2：Sample Selection and Data Sources:
Inconel 625 plates of 110 x 80 x 5 mm thickness are chosen as workpiece material. The butt weld joint is made with these plates.
3：List of Experimental Equipment and Materials:
CO2 Laser welding machine, Vernier height gauge for distortion measurement, and radiography equipment for weld quality analysis.
4：Experimental Procedures and Operational Workflow:
Edge preparation of base plates is done with CNC milling. Welding is performed with zero gaps between the butting edges. Distortion is measured post-welding, and radiography analysis is conducted to assess weld quality.
5：Data Analysis Methods:
Heat input is calculated using a specific equation. Distortion and bead geometry are analyzed to understand the effects of varying process parameters.
