A dataset for "A high-performance WAAM process for Al-Mg-Mn using controlled short-circuiting metal transfer at increased wire feed rate and increased travel speed"

In the study, a high-performance controlled short-circuiting metal transfer process at a wire feed rate of 12 m/min for WAAM with an Al-Mg-Mn alloying system was developed. The arc current and voltage waveforms were studied by oscillograms processing and then modified to reduce energy input in comparison with a self-regulated gas metal arc welding process. The newly developed process was implemented in manufacturing of the sample parts at a travel speed of up to 150 cm/min. Modified waveforms in a combination with an increased travel speed led to a decrease in heat input, which appeared to be 16% lower than that of a conventional self-regulated process. Decreased heat input lead to an improvement of the geometry preservation stability at high process rates (up to 2.2 kg/h). The mechanical properties study showed that the elongation of the tensile samples was up to 41%, the increase in elongation was explained through macro- and microstructure analysis. The provided data shows remarkable tensile test results and remarkable macro- and microstructure images, which were used to evaluate porosity and grain size in the study of the deposited metal properties. High-speed video of a metal transfer during deposition using the newly developed process along with a high-speed video of a wire feeding process are also presented in this dataset.本研究针对采用Al-Mg-Mn合金体系的电弧增材制造（Wire Arc Additive Manufacturing, WAAM），开发了送丝速度为12 m/min的高性能控制短路过渡工艺。通过示波图处理分析电弧电流与电压波形，并相较于自调节式熔化极气体保护焊工艺，对波形进行优化以降低热输入。将所开发的新工艺应用于试样零件制造，其移动速度可达150 cm/min。优化后的波形结合更高的移动速度，使得热输入降低，相较于传统自调节工艺，热输入降幅达16%。热输入的降低提升了高工艺速率（最高2.2 kg/h）下的成形几何精度稳定性。力学性能测试结果表明，拉伸试样的断后伸长率可达41%，通过宏观与微观组织分析可解释该断后伸长率的提升现象。本数据集提供了优异的拉伸测试结果与宏观、微观组织图像，这些数据与图像用于评估沉积金属性能研究中的气孔率与晶粒尺寸。此外，本数据集还包含采用新工艺进行沉积过程中的金属过渡高速视频，以及送丝过程的高速视频。
