Problems solved by technology

[0004] The risk of weld cracking cannot be fundamentally eliminated by using laser air melting and spot swing. During the actual product assembly process, the weld gap fluctuates from 0 to 0.30 mm, and factors such as welding equipment and product reflectivity are also likely to cause actual welding power. Fluctuation problem, so a little carelessness may cause fluctuations in fusion rate, resulting in cracks or poor fusion defects in the weld, affecting engineering applications

Description

technical field [0001] The application relates to a nickel-based alloy welding powder and its production method and use (welding) method, which are mainly suitable for producing nickel-iron-based filler powder for laser welding of low-carbon steel and gray cast iron and its use method. Background technique [0002] Welding of mild steel and cast iron dissimilar metal materials is commonly used in various product structures. The structure of gray cast iron is formed by the graphitization process when the molten iron is slowly cooled, and is mainly composed of flake graphite and pearlite matrix. Flake graphite is equivalent to small cracks in cast iron, splitting the matrix, reducing the effective damage area of ​​steel, reducing the strength of gray cast iron, and almost zero plasticity. The chemical composition of cast iron is relatively special, with high content of carbon, silicon, sulfur and phosphorus, among which sulfur and phosphorus are impurity elements, while low c...
