摘要:
S355NL细晶粒结构钢以其优异的性能在海上风电、石油平台、焊接钢管等方面得到广泛应用。为进一步提高焊接钢管的生产效率,获得性能优良的海上风机基础用钢管焊接接头,开展S355NL直缝焊管的焊接工艺研究。采用双丝埋弧焊方式,选用低镍合金焊材,不仅能够细化焊缝组织晶粒,同时降低淬硬倾向,提高S355NL直缝焊管焊缝的低温冲击韧性。在焊接过程中采用多层多道焊接,控制热输入≤ 5.0 kJ/mm,减少熔合区和热影响区在高温区域停留时间,保证熔合线和热影响区冲击性能。试验结果表明,该工艺所制试板及成品焊管各项力学性能试验合格,能够满足-40 ℃夏比冲击试验要求。生产应用表明,该焊接工艺制定及焊材选配正确恰当,能够提高焊接生产效率。
Abstract:
S355NL fine?rained structural steel has been widely used in offshore wind power, oil platforms, welded steel pipes and other fields due to its excellent performance. In order to further improve the production efficiency of welded steel pipe and obtain the welded joint of steel pipe for offshore wind turbine foundation with excellent performance, the welding process research of S355NL longitudinal welded pipe was carried out. Adopting double?ire submerged arc welding and low?ickel alloy welding material can not only refine the grain of weld, but also reduce the hardening tendency and improve the low?emperature impact toughness of S355NL longitudinal welded pipe weld. Multi?ayer and multi?ass welding is adopted in the welding process, the heat input is controlled to be ≤ 5.0 kJ/mm, the residence time of fusion zone and heat affected zone in the high temperature zone is reduced, and the impact performance of fusion line and heat affected zone is guaranteed. The test results show that the mechanical properties of the test plate and the finished welded pipe manufactured by this process are qualified and can meet the requirements of -40 ℃ Charpy impact test. The production application shows that the welding process formulation and welding material selection are correct and appropriate, and the welding production efficiency is improved at the same time.
