摘要

异种金属焊接(DMW)广泛应用于各行各业的加工制造中。镍基合金和铁素体钢管道和管道之间的连接通常用于符合ASME规范的焊接,用于高温和耐腐蚀应用。采用不同的焊接工艺、接头设计和焊接技术,制备了一系列合金600管与SA-106 B级管之间的DMW试样。通过详细对比,深入分析了不同焊接变量对焊接接头力学性能(焊接材料的拉伸性能、硬度和热影响区)、金相性能(宏观和微观组织检查)和化学性能(根道合金稀释等)的影响。两种材料的熔化温度有利于根焊过程中形成良好的焊头。不同的接头设计(如带或不带消耗性插入件)会对焊缝稀释和根部的Cr/Ni回收率产生影响。讨论了DMW根部通焊的钨极位置、热丝和冷丝的机器气体钨极保护焊(GTAW)等其他焊接变量。

Effects of Welding Processes and Techniques on Mechanical and Metallurgical Properties of Dissimilar Metal Weld
The dissimilar metal weld (DMW) is widely used in fabrication and manufacturing in various industries. Joining between nickel-based alloy and ferritic steel tubing and piping is commonly employed for ASME Code compliant welds for high-temperature and corrosion resistance applications. A series of DMW samples between alloy 600 pipe and SA-106 Grade B pipe are fabricated using different welding processes, joint design and welding techniques. By detailed comparison, this paper provides insight into the effects of these different welding variables on mechanical properties (tensile properties and hardness of weld materials and heat affected zone), metallurgical properties (macro and microstructure examination) and chemistry (root pass alloying dilution etc.) It has been shown that an asymmetric joint bevel design in consideration of different heat dissipation, melting temperature of the two materials will promote good weld bead formation during the root pass welding. Different joint designs (such as with or without consumable insert) will create variations on weld dilution and Cr/Ni recovery in the root area. Other welding variables such as tungsten electrode location for root pass welding for DMW, machine Gas Tungsten Arc Welding (GTAW) using hot wire and cold wire, etc. are also discussed.
