摘要
在药芯焊丝中使用放热添加剂（EA）作为电荷是改善焊接接头技术特性的一种可行方法。我们建立了数学模型来确定电荷密度和填充因子，它们取决于 EA 含量、石墨与 EA 氧化剂的比例 (CuO/C) 以及 EA 成分中氧化剂与铝粉的比例 (CuO/Al)。所研究的熔融模式主要取决于这些参数：EA = 26-28 质量%，CuO/C = 4.0-4.5 和 CuO/Al = 4.50-5.25。
Prediction of Fill Factor and Charge Density of Self-Shielding Flux-Cored Wire with Variable Composition
The use of exothermic addition (EA) for charge in flux-cored wire is a promising way to improve technological characteristics of welded joints. The mathematical models to determine the charge density and the fill factor, which depend on the EA content, the ratio of graphite to EA oxidizer (CuO/C) and the ratio of the oxidizer to the aluminum powder in the composition of the EA (CuO/Al) were built. The investigated fusion modes depend mostly on such parameters: EA = 26–28 mass%, CuO/C = 4.0–4.5 and CuO/Al = 4.50–5.25.
