摘要

铁素体/马氏体钢和奥氏体不锈钢是高强度钢材,在高温高压应用中备受推崇。一般来说,多金属与不同的铬镍铁合金可用于连接。这是一个相当复杂和耗时的过程。目前的工作展示了使用活化钨极惰性气体(A-TIG)焊接工艺一次焊接 8 毫米厚的 P91 钢板和 316L SS 板所做的努力。主要挑战在于获得对称的焊缝轮廓。焊剂涂层需要在焊剂成分、涂层密度和涂层模式方面进行优化,以获得对称外观的全熔透。目前的工作讨论了异种焊接过程中出现不对称的可能原因及其解决方案。研究发现,不同的焊剂涂层密度在控制弧柱形状、流体流动以及焊缝几何形状方面非常有效。与 316L 焊缝相比,P91 焊缝采用了较高的涂层密度。在 A-TIG 焊接过程中,通过使用多组分焊剂(33-38% TiO2、38-43% SiO2、13-17% NiO 和 8-10% CuO),实现了对称焊接轮廓和全熔透。

Role of Activating Flux in Weld Bead Symmetricity during Dissimilar Metal Joining

Role of Activating Flux in Weld Bead Symmetricity during Dissimilar Metal Joining

Ferritic/martensitic steels and austenitic stainless steels are high-strength steels, and highly recommended in high-temperature and high-pressure application. In general, multimetallics with different Inconel alloys are used for joining. This is quite a complex and time-consuming procedure. The current work demonstrates the efforts made to weld 8 mm-thick P91 steel and 316L SS plates in a single pass using activating flux tungsten inert gas (A-TIG) welding process without any interlayers. The main challenge is to get the symmetric weld bead profile. Flux coating is optimized in terms of flux composition, coating density, and coating pattern to get the full penetration with symmetric appearance. The current work discusses the possible cause and their solution of asymmetricity during dissimilar welding. Differential flux coating density is found to be very effective in controlling the arc column shape, fluid flow, and consequently the bead geometry. High coating density is used in the P91 side compared to 316L side. Symmetric weld profile with full penetration is achieved by applying multicomponent flux (33–38% TiO2, 38–43% SiO2, 13–17% NiO, and 8–10% CuO) during A-TIG welding.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
