摘要
通过焊接技术对金属微结构进行处理，在微观电子电路和光电结构方面有着多种应用，因此吸引了许多人的兴趣。在雕刻金属微结构的过程中，对结构的重新填充和删除是一项挑战。我们提出了微尺寸气体钨极氩弧焊（GTAW）技术来克服这些挑战。通过使用蚀刻的 100 μm W 焊丝以及优化的电弧电流和电压控制，实现了 ~ 10 s μm 的焊接面积。在适当的氩气流条件下，英钢表面焊点的空间尺寸和深度与电弧电流和电压有关。我们相信，这些结果可以为开发许多工业应用提供技术直观性。
Micro-scale gas tungsten arc welding on invar sheet
Manipulation of metal microstructures via welding technique has attracted many interests due to its various applications for microscopic electronic circuits and photo-electronic structures. Refilling deletion of structures is challenging in sculpting metal microstructure. We propose the micro-size gas tungsten arc welding (GTAW) technique to overcome these challenges. The welded area of ~ 10 s μm are achieved by using an etched 100 μm W wire with optimized arc current and voltage control. The spatial size and depth of the welded spot in the invar surface show dependency on the arc current and voltages under proper Ar gas flow. We believe that these results can provide technical intuition for developing many industrial applications.
