工艺参数对5052铝镁合金焊缝凝固裂纹敏感性的影响
Influence of Technology Parameters on Weld Solidification Crack Sensitivity of 5052 Al-Mg Alloy
摘 要
采用鱼骨状裂纹试验对比研究了熔化极惰性气体保护焊（MIG）焊接时保护气体、焊接电流和脉冲模式等焊接工艺参数对5052铝镁合金焊缝凝固裂纹敏感性的影响。结果表明：随焊接电流增大和保护气体中氦气比例的增加，焊缝凝固裂纹敏感性变大；方形电流波形的双脉冲MIG的焊缝凝固裂纹敏感性大于单脉冲MIG的；晶界镁含量增加，焊缝会形成连续晶界，有利于降低焊缝凝固裂纹敏感性。

Abstract
The influence of welding parameters, including shielding gas, welding current and pulse mode, on the weld solidification crack sensitivity of 5052 Al-Mg alloy in melt inert-gas welding (MIG) was investigated by fishbone testing. The results show that the weld solidification crack sensitivity increase with the increase of welding current and the proportion of helium in shielding gas. The weld solidification crack sensitivity of double pulse MIG with square current waveform was higher than that of single pulse MIG. With the increase of Mg content in grain boundary, continuous grain boundary will be formed in the weld, which is beneficial to reduce the weld solidification crack sensitivity.
