Control System for CO2 Welding Power Source with Time-dependent Output Characteristic

    摘要
  • 摘要: 建立了单片机控制的IGBT逆变弧焊电源系统,能够根据电弧的状态实时调整其外特性,满足焊接工艺要求。用于CO2焊接过程的控制,成功地减少了燃弧过程中的瞬时短路次数,降低了飞溅率,并提高燃弧功率,改善了焊缝成形。该方法对焊接过程中弧长的扰动具有较强的适应性,尤其适于半自动焊接过程。

     

    Abstract: A microcomputer control system for arc selding with IGBT inverter power source was developed in this paper,which is able to meet the requirement of the welding process by adjusting the output characterristic according to arc states.The system reduses instantaneous short circuit possibility and spatter during CO2 welding process,increases burning arc power and improves bead formation.Experiments have proved that it has strong adaptability to distrurbance of arc length,and is particularly suitable for semi-automatic welding process.
