摘要:
介绍了?准355.6 mm×(10+3) mm规格L360QS+316L不锈钢复合钢管的新型焊接工艺,即首先采用TIG焊在复合钢管管端进行堆焊预处理,然后再采用氩气保护TIG焊进行对焊操作。为评价环焊缝的性能,焊后对其焊接接头进行了拉伸试验、冲击试验、硬度测试、晶间腐蚀及应力腐蚀试验。试验结果表明,采用该工艺焊接的L360QS+316L不锈钢复合钢管环焊缝焊接接头性能良好,且具备耐晶间腐蚀和应力腐蚀性能;堆焊层起到了很好的隔离作用,保证了焊缝的质量。
Abstract:
This paper described new welding process on the L360QS/316L clad pipe with size of ?准355.6mm×(10+3) mm. Firstly, it adopted TIG welding to conduct overlaying on the pipe end, and then, using TIG welding process for butt welding with argon gas protection. The tensile strength, charpy impact test, hardness, intergranular corrosion test and SCC were carried out to study the properties of the circumferential weld. The results indicated that the welded joint performance of the circumferential weld is good; it is with resistance to intergranular corrosion and stress corrosion. The overlay welding layer plays a good role in isolation function to ensure the weld quality.
