摘　　要：在海底管道铺设中,稳定、高效的焊接工艺对管道焊接质量和焊接效率尤为重要。采用自主研制的双炬双丝全位置焊接小车,配备专用轨道对φ711材质为API X65的海管进行组对焊接,经过大量实验得到合适的焊接工艺。实验结果表明,焊缝成形良好,经过UT检测合格,拉伸、侧弯和刻槽锤断试验均符合API 1104-2005标准。The stable and efficient welding process is particularly important for submarine pipeline welding quality and efficiency in submarine pipeline laying.The submarine pipelines with the diameter of 711 and material of API X65 were assembled and welded using the independently developed double-torch and double-wire welding robot equipped with dedicated orbit.The proper welding parameters were obtained through a amount of experiments.The experimental results show the good welding seam forming.The UT inspection,tensile,side bend and nick-breaks text results all meet the API 1104-2005 standards.
