摘要
针对材质为TP347φ406×60 mm的不锈钢管进行全位置高频窄间隙自动焊接。分析窄间隙坡口尺寸和焊接工艺参数对焊缝成型的影响,试验结果表明,焊接接头的抗拉强度、低温冲击韧性、低温裂纹尖端张开位移值均满足要求。
In this paper,All-position high frequency narrow gap hot wire TIG welding was used in TP347 stainless steel pipe.Analyze the narrow clearance groove size and the influence of welding parameters on weld forming.The tests show the tensile Strength,impact value and CTOD value under low temperature of welded joints have excellent mechanical properties.
