Metal molten behavior with ultra high frequency pulsed arc welding

  • 摘要: 熔池金属流动一方面受电弧行为影响,另一方面与凝固组织形核、结晶过程联系紧密,是电弧焊接基础研究的关键,针对电弧力作用研究了超高频脉冲电弧焊接(UHFP-AW,Ultra High Frequency Pulsed Arc Welding)熔池金属流动特点,采用理论研究与试验分析相结合的方式对熔池流动方式、强度、温度分布等要素进行了分析,并完成了液态金属表面运动特征监测.结果表明,超高频脉冲电弧对熔池液态金属的热、力作用显著,表面流体流速大于30cm/s,UHFP-AW电弧力造成熔池表面沉降变形,引起双环流,熔池温度扩散范围相应减小,有效降低了电弧热量对母材金属的影响,尤其在钛合金焊接中对控制焊缝晶粒尺寸具有重要意义.
