摘　　要：通过对60 mm厚5A06铝合金进行电子束焊工艺试验,分析了其电子束焊焊接特点,提出了合理的电子束焊焊接工艺,同时还进行了焊缝质量检验,分析了焊接接头的显微组织并测试了其力学性能。结果表明:强化表面处理、调整工艺参数、采用中等偏下的焊接速度、采用重熔修饰焊是保证良好焊接质量的关键点;在此基础上确定了5A06铝合金厚板电子束焊工艺规范,且焊缝强度可以达到母材强度的80%以上。The electron beam welding experiment for 5A06 aluminum alloy with 60 mm thick plate was carried out. The welding characteristic of electron beam welding technique were analyzed. The welding seam quality was checked. The mechanical properties of the welded joint were analyzed. The results show that strengthening surface treatment, adjusting process parameters, using below average welding speed and remelting modification welding are the key points to ensure the good welding quality. The, the electron beam welding process was ensured, and the strength of weld seam is more than 80% of base metal.
