Abstract

Abstract Submerged arc welding (SAW) is a type of welding process having wide range of applications like in fabrication of pressure vessel, pipe line, off shore structures, oil industry, etc., because of its high melting efficiency, high production rate and automation. Weld input factors such as welding voltage, welding current, travel speed, nozzle to plate distance and electrode diameter have a significant impact on the standard of created weld bead. Response surface methodology is used in the present work to find out the influence of welding voltage, welding current and travel speed on weld bead geometry. Face centred central composite design technique of RSM is used for Design of Experiment. It has been discovered that weld bead width grows with higher welding voltage but there is decrease in weld bead height, with increase in welding current there is increase in both weld bead width and weld bead height also but when travel speed is increased there is decrease in both weld bead width and weld bead height. The genetic algorithm for minimization of both weld bead width and height is also done. The predicted results from the created mathematical model, optimized model and the related experimental result are in good agreement.

SS-304钢SAW焊包层特性的统计建模与优化

埋弧焊（SAW）是一种焊接工艺，由于其熔化效率高、生产率高、自动化程度高，在压力容器、管道、海上结构、石油工业等领域有着广泛的应用。焊接电压、焊接电流、行进速度、喷嘴到板的距离和电极直径等焊接输入因素对生成的焊道的标准有显著影响。本文采用响应面法研究了焊接电压、焊接电流和行进速度对焊缝几何形状的影响。实验设计采用了RSM的面心中心复合材料设计技术。已经发现，焊缝宽度随着焊接电压的升高而增大，但焊缝高度减小，随着焊接电流的增加，焊缝宽度和焊缝高度也增大，但当行进速度增加时，焊缝宽度与焊缝高度都减小。文中还给出了使焊缝宽度和高度最小化的遗传算法。建立的数学模型、优化模型的预测结果与相关实验结果吻合较好。
