激光-短路MAG复合热源焊接过程稳定性的影响因素

Two factors influencing welding process stability of Nd:YAG laser-short circuit arc MAG hybrid welding

    摘要
  • 摘要: 以低碳钢为研究对象,通过焊接电弧分析仪,对比研究了激光-短路MAG电弧复合热源焊接过程中焊接速度、激光与电弧的相对位置对焊接过程稳定性的影响规律.结果表明,随着焊接速度增加,MAG和激光-短路MAG复合热源焊接过程稳定性都会降低,但由于激光的引入,复合热源在高速焊接过程更稳定.与MAG相比,复合热源可以提高极限焊接速度1倍以上;复合热源焊接过程中,与激光在前引导焊接相比,电弧在前引导焊接过程稳定性更高.

     

    Abstract: The effects of welding speed and welding direction on Nd:YAG laser-short current MAG hybrid welding stability were investigated. The experimental results showed that welding arc stability of MAG and laser+MAG would decrease with the increasing of welding speed, but the arc of laser+MAG get more stable comparing with MAG arc. The maximal welding speed of laser+MAG is more than one time fast comparing with that of MAG. The hybrid welding arc in arc leading direction would get more stable comparing with that of laser leading direction.
