摘要: |
介绍了一种新型交流MAG焊接电弧稳定性及其控制的研究成果。提出了一种崭新的双凹电流波形,解决了MAG焊交流电弧稳定这个一直很难解决的问题。对交流脉冲MAG焊接电弧稳定性进行了较为系统的研究表明,脉冲参数是影响电弧稳定和实现合理熔滴过渡的最主要因素,保护气体成分和流量、稳弧剂也是重要的影响因素。经过精心配置焊接参数的交流脉冲MAG焊接法能实现电弧稳定并具有较合理的熔滴过渡形式,是一种具有重要应用前景的焊接方法。 |

Abstract: |
A new A. C. pulsed MAG welding process was introduced in this paper. A brand-new welding current waveform for stabilizing the A. C. MAG welding arc has been put forward, and the welding test has been performed with satisfactorg results. A set of reasonable pulse parameters was proposed on the welding testing results. Other facttors influencing the arc stability have also been studied. |
