摘要

在100 ~ 1500 Hz的不同脉冲频率下，对304h3 mm厚直流负极（DCEN）铜进行了高频脉冲气钨弧（GTA）焊接试验。对于一组固定的优化焊接参数，熔透深度随脉冲频率的增加而增加，这是由于高频脉冲时电弧收缩造成的。采用光学显微镜和扫描电镜对焊缝进行了显微组织表征。在1000 Hz和1500 Hz下产生的全熔透焊缝具有良好的枝晶组织，力学性能优于传统的气体钨极电弧焊。

High frequency pulse gas tungsten arc welding of 304HCu stainless steel Hochfrequenz-Impuls-Wolframinertgasschweißen von rostfreiem Stahl X3CrNiCu18-9

High-frequency pulse gas tungsten arc (GTA) welding was explored for 3 mm thick 304HCu with direct current electrode negative (DCEN) polarity at different pulse frequencies from 100 Hz to 1500 Hz. For a fixed set of optimized welding parameters, the depth of penetration increased with increasing pulse frequency, which was attributed to arc constriction during the high frequency pulsing. Optical and scanning electron microscopy were performed for the microstructural characterization of the welds. Full penetration welds produced at 1000 Hz and 1500 Hz had a fine dendritic structure with mechanical properties better than the conventional gas tungsten arc weld.

期刊介绍： Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing. Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline. Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
