摘要
通过理论分析与试验对比的方法研究了油气管道激光-电弧复合焊接过程中电弧电压、送丝速度、激光能量、激光离焦量、激光入射角度、光丝间距等参数对焊接成型和焊接质量的影响,探讨了各参数设定的参考值。研究结果表明:激光-电弧复合焊接机理复杂,其众多焊接参数之间相互影响,在进行焊接工艺研究时需要有机联系、系统分析。较好焊接效果的工艺参数不止一组,通过进一步研究激光-电弧复合焊接作用机理,可以得到适合不同情况的多组焊接工艺参数,进而有效地指导管道激光-电弧复合焊接技术的工程应用。
To identify the parameters of laser-arc hybrid welding process for large-diameter oil/gas pipelines, theoretical analysis and comparative tests are conducted to study impacts of such parameters as arc voltage, wire delivery speed, laser intensity, defocusing amount, laser incident angle, and laser-arc distance on forming and quality of welding operations. Moreover, set reference values for the parameters are proposed. Research results show that the laser-arc hybrid welding has a complex mechanism and its numerous welding parameters have interactions during welding operations. To identify optimal welding processes, all these parameters shall be analyzed systematically. In fact, there are multiple sets of parameters available to achieve satisfactory welding performances. Through in-depth researches for mechanisms of the laser-arc hybrid welding, multiple process parameters suitable for different working conditions can be identified. Relevant research results may provide guidance for application of the laser-arc hybrid welding process in pipeline industry.
