In recent years, chain technology has achieved breakthroughs in high-temperature resistance, corrosion resistance, and impact resistance. However, welding nickel-based alloy chain structures remains a challenge. The welding difficulties stem not only from the material's welding characteristics but also from the unique structural form of the chain—its flexible chain structure. The entire manufacturing process is complex, including: (1) The effect of residual stress after stamping of nickel-based alloy chain parts on welding; (2) Chain braiding will affect the welding operation; (3) The shape of the chain bevel cannot be guaranteed, which affects the welding quality; (4) The chain weld is deep and short, making it difficult to handle the welded arc termination joint; (5) The chain weld is an X-shaped groove, which must be welded on both sides, making the welding operation inconvenient.
