Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] Spray forming technology is developed from the traditional rapid solidification powder metallurgy process. It is a rapid solidification and near net forming material billet technology. Compared with the traditional casting process, spray forming, as a new generation of solidification technology, improves the solidification unit from centimeter level (semi / continuous casting) to micron level, which can greatly increase the solidification rate, and is a disruptive technology for the pr...

Abstract

The invention provides a preparing process of a welding wire suitable for fusion welding of a spray-formed ultrahigh-strength aluminum alloy plate. The process includes the steps of material preparing, vacuum smelting, powder atomizing, powder screening, ball-milling and powder mixing, vacuum canning, hot isostatic pressing, lathing, hot extruding and the like. The welding wire produced through the method does not need to be homogenized, saves energy and shortens the welding wire production process. Surplus crystal-phase particles in the prepared welding wire are small in size and are evenly dispersed and distributed, drawing breakage of the wire is reduced, the yield of the welding wire is increased, production cost is reduced, the welding performance of the welding wire and the metal strength of a weld joint can be improved, and the welding wire is particularly suitable for fusion welding of the spray-formed ultrahigh-strength aluminum alloy plate.

Description

technical field [0001] The invention relates to the technical field of welding wire production and preparation, in particular to a welding wire preparation process suitable for fusion welding of spray-formed ultra-high-strength aluminum alloy plates. Background technique [0002] Ultra-high-strength aluminum alloy is an Al-Zn-Mg-Cu high-strength aluminum alloy with Zn as the main strengthening element. It has the advantages of low density, good toughness, high specific strength, high specific stiffness, and excellent stress corrosion resistance. Ultra-high strength is the high-strength aluminum alloy with the best comprehensive performance at present, and has been widely used in aerospace, transportation, shipbuilding, nuclear industry and other fields for a long time. Ultra-high-strength aluminum alloy is a typical structural material, and its weldability is an important process performance index of ultra-high-strength aluminum alloy. Its large-scale use is limited due to i...
