Abstract

The invention discloses a nickel-based alloy stranded electric welding rod and a preparation method thereof. The electric welding rod comprises a core wire (1), the periphery of the core wire (1) is coated with a coating (2), the core wire (1) comprises a central stranded welding wire (101), and a plurality of strands of peripheral stranded welding wires (102) are arranged on the periphery of thecentral stranded welding wire (101) in a stranded mode, the central stranded welding wire (101) and the peripheral stranded welding wires (102) are formed by stranding a plurality of strands of singlewires, the single wires of the central stranded welding wire (101) are solid welding wires, and the single wires of the peripheral stranded welding wires (102) are flux-cored wires. According to thenickel-based alloy stranded electric welding rod and the preparation method thereof, the problems that large-scale welding is difficult, and the welding efficiency is low can be solved.

Description

technical field [0001] The invention relates to an electric welding electrode and a preparation method thereof, in particular to a nickel-based alloy stranded electric welding electrode and a preparation method thereof. Background technique [0002] The electrode is a melting electrode coated with a coating for arc welding. It is composed of two parts: the coating and the welding wire. Special steel wires for welding can be divided into three categories: carbon structural steel, alloy structural steel, and stainless steel. Electrode coating refers to the coating layer applied to the surface of the welding wire. The coating decomposes and melts during the welding process to form gas and slag, which play the role of mechanical protection, metallurgical treatment, and improvement of process performance. The welding wire is wrapped in the coating, which determines the welding quality together with the coating. [0003] There are following defects in the nickel-based material ...
