通过应变硬化的高强度镍合金焊接
摘要：
本发明提供应变硬化的高强度镍基合金焊接点，其在接合高强度金属时产生改进的性质和性能。有利的焊件包括两个或更多个铁或非铁构件片段，和使相邻的构件片段结合在一起的熔融焊接点、摩擦搅拌焊接点、电子束焊接点、激光束焊接点或其组合，其中该焊接点包含应变硬化的镍基合金焊接金属组合物，该组合物基于镍基合金焊接金属组合物的总重量包含大于或等于10wt％的Mo。本发明还提供了用于从镍基合金焊接组合物形成焊接点的方法。应变硬化的高强度镍基合金焊接点用于石油、天然气和石化工业中，用于天然气输送和储存、油和气井完井和生产、以及油和气精炼厂和化工厂。
摘要（英）：

Provided are strain hardened high strength nickel based alloy welds that yield improved properties and performance in joining high strength metals. The advantageous weldments include two or more segments of ferrous or non-ferrous components, and fusion welds, friction stir welds, electron beam welds, laser beam welds, or a combination thereof bonding adjacent segments of the components together, wherein the welds comprise a strain hardened nickel based alloy weld metal composition including greater than or equal to 10 wt% Mo based on the total weight of the nickel based alloy weld metal composition. Also provided are methods for forming the welds from the nickel based alloy weld compositions. The strain hardened high strength nickel based alloy welds are useful in the oil, gas and petrochemical industry in applications for natural gas transportation and storage, oil and gas well completion and production, and oil and gas refinery and chemical plants.
