ENI 429 is a basic-coated electrode developed for joining nickel-based alloys and similar heat-resistant materials, offering high performance at service temperatures up to 1000°C. It is suitable for welding alloys such as 2.4663 (NiCr21Co12Mo), 2.4851 (NiCr23Fe), 1.4876 (X10 NiCrAlTi 32 20), and 1.4859 (GX 10 NiCrNb 32 20). Provides strong resistance to oxidizing and carburizing atmospheres, with scaling resistance up to 1100°C. The weld metal shows excellent resistance to hot cracking and maintains high-temperature strength even without post-weld heat treatment. It produces a stable arc, smooth weld bead, and has easily removable slag for efficient operation. ENI 429 is ideal for high-temperature applications like gas turbines, ethylene plants, chemical reactors, and petrochemical equipment. Preheating should be adjusted according to the base material to minimize residual stress and reduce cracking risk.
