摘要

在电子束焊接中，聚焦电流和扫描模式联合控制着束流在工件表面的能量分布，对焊缝成形有重要影响。基于5A06铝合金试板匹配5B06焊丝的表面堆焊试验，通过单一变量法研究了聚焦电流变化和扫描波形、频率及幅值对电子束填丝焊焊缝成形的影响。结果表明，为保证束流能量密度能够充分熔化焊丝，获得良好的焊缝成形，聚焦电流的可调范围比较窄，与表面聚焦电流的偏差需要控制在-5~+10 mA范围内；若通过扫描模式减少焊缝气孔缺陷，优选圆形扫描，且扫描频率和幅值应分别控制在500~1 000 Hz、0.8~1.2 mm范围内。

Abstract

The focusing current and scanning mode jointly control the energy distribution of the electron beam on the workpiece surface, which has an important impact on weld formation in electron beam welding. Based on the surfacing welding test of 5A06 aluminum alloy plate matched with 5B06 welding wire, the effects of focusing current change, scanning waveform, frequency and amplitude on weld formation in electron beam wire filling welding were studied by single variable method. The results show that in order to ensure that the beam energy density is enough to fully melt the welding wire and then obtain good weld formation, the adjustable range of focusing current is relatively narrow, and the deviation from the surface focusing current needs to be controlled within -5~+10 mA. If the porosity defect of the weld is reduced by scanning mode, circular scanning is preferred, and the scanning frequency and amplitude should be controlled within the range of 500~1 000 Hz and 0.8~1.2 mm, respectively.
