焊接过程中的热输入是与所得微观结构相关的焊接质量和使用性能的基本指标。在这项研究中,铝合金5083搅拌摩擦焊接过程中的热量输入在不同的焊接工艺参数进行了测量。对数据进行多元回归分析,以确定经验方程来估计输入变量的热输入。还研究了热输入对搅拌区晶粒尺寸的影响,得到了晶粒尺寸与热输入之间的良好相关性。通过实验测量,获得了搅拌区输入变量、热输入和晶粒尺寸之间的系统关系。
Heat input during welding is a basic index for weld quality and service properties associated with the resulting microstructure. In this study, the heat inputs during friction stir welding of Al alloy 5083 at various welding parameters were measured by calorimetry. Multiple regression analysis of the data was conducted to determine an empirical equation to estimate the heat input with the input variables. The effect of the heat input on the grain size of the stir zone was also examined, and a good correlation between the grain size and heat input was obtained. This study obtained a systematic relationship between the input variables, heat input and grain size of the stir zone through experimental measurements.
