Abstract

The weldability and mechanical properties of welded joints of pipeline steels of grades API 5L (X52, X60, X65 and X70) manufactured by submerged arc welding (SAW) are investigated. It is shown that the SAW process makes it possible to obtain high-quality welded joints. It is shown that such welded joints fracture during tensile tests over the base metal region. The weld region has the highest hardness and ultimate tensile strength, which are 214 HV₁₀ and 713 MPa for steels X70 and X65 respectively. These values are higher than that of the base metal.

埋弧焊连接管道钢焊接接头的力学性能

研究了API 5L牌号（X52、X60、X65和X70）管线钢埋弧焊焊接接头的可焊性和力学性能。结果表明，SAW工艺可以获得高质量的焊接接头。结果表明，这种焊接接头在母材区域的拉伸试验中断裂。焊缝区硬度和极限抗拉强度最高，X70和X65钢的硬度和极限抗拉强度分别为214 HV10和713 MPa。这些值高于母材的值。
