摘要: 利用焊接电弧电压信号的标准差和差异系数的倒数作为评价电弧稳定性的指标,通过试验研究了不同工艺条件下水下湿法药芯焊丝焊接的电弧稳定性.建立了湿法焊接电弧稳定性的敏感度模型,分析了各工艺参数如焊接电流、电弧电压、焊接速度和水深对湿法药芯焊丝焊接电弧稳定性的影响.结果表明,水深增大时,焊接电弧稳定性变差,特别是在浅水区域,增大水深可显著降低电弧稳定性;焊接速度增大,电弧稳定性变差;焊接电压对电弧稳定性影响很大,适当提高焊接电压可提高电弧的稳定性.Abstract: Standard deviation(SD) and the reciprocal of coefficient of variation(CV) of welding voltage are used as the index of arc stability.The arc stability of underwater wet flux-cored arc welding in different welding conditions was studied based on underwater wet welding experiments.Sensitivity models of arc stability have been built and sensitivities of welding parameters on arc stability, such as welding current, voltage, speed and water depth, were analyzed.The results showed that the arc stability got worse as water depth increased.Especially in shallow water, the arc stability decreased dramatically as the water depth increased.Arc stability also decreases with the increasing of welding speed.The welding voltage has a great influence on arc stability and increasing the welding voltage appropriately will improve the arc stability.
