摘　　要：针对合成氨装置气化炉烧嘴Inconel 600镍基耐热合金盘管焊缝热影响区发生开裂的问题,通过焊接技术攻关和创新,提高了烧嘴焊接质量,延长了烧嘴运行周期,保证了化肥装置长周期运行。Inconel 600 nickel-based heat resistant alloy seam in the heating zone in the coiler can be cracked easily. Through welding technology innovation, burner weld quality was improved, the operation cycle was prolonged, which guaranteed the fertilizer plant running in a long term.
