Abstract

The invention discloses a Mn-Cu-based welding wire and its preparation method and application. The Mn-Cu-based welding wire comprises the following components in mass percentage: copper 35-43%, manganese 50-60%, aluminum 0.5-2%, tin 0.5-1%, zinc ≤ 3%, chromium ≤ 0.9%. The welding wire preparation method includes: charging; melting; refining; casting; homogenizing; forging; extruding; drawing; annealing. The welding wire in the present invention is mainly used for the welding of Mn-Cu alloy and Mn-Cu alloy or steel. The welding wire of the invention solves the problem of severe welding hot cracks during fusion welding of Mn-Cu alloy and steel, resulting in poor mechanical properties of weld metal and joints. The weld metal has higher damping performance after heat treatment using the existing alloy welding wire. By realizing the connection of Mn-Cu alloy and steel to obtain high-strength and high-damping composite materials, the application prospects of Mn-Cu alloy can be broadened.

Description

technical field [0001] The invention belongs to the technical field of welding materials, and in particular relates to a Mn-Cu-based welding wire and a preparation method and application thereof. Background technique [0002] Today, with the rapid development of science and technology, people have put forward more and higher requirements for materials. However, the performance of a single material is relatively limited, and high-performance materials are relatively expensive. Therefore, more and more materials with different properties are required to be used in combination, which involves the connection of a large number of dissimilar materials. Mn-Cu-based damping materials are widely used in aerospace, marine, machinery and other fields. Mn-Cu-based damping materials play a very significant role in suppressing noise and vibration and improving the stability and reliability of equipment. Damping alloys have excellent process performance and high damping performance, so t...
