Problems solved by technology

[0004] However, the types of arc cladding powder core wire materials currently on the market are relatively single, and powder core wire materials suitable for carbon steel types are even scarcer. In mechanical work applied to repairing carbon steel, the repaired cladding layer or weld bead Defects such as pores and cracks are prone to occur, and mechanical properties such as hardness, density and tensile strength cannot meet the required repair standards

Abstract

The invention relates to a Fe-Mn-Cu powder core wire and an arc additive processing process thereof. The Fe-Mn-Cu powder core wire is composed of a low-carbon steel strip and a Fe-Mn-Cu powder core. The prepared Fe-Mn-Cu powder core wire is used for performing arc additive processing on a damaged carbon steel substrate, and the damaged carbon steel substrate is repaired after processing; and a remanufactured and repaired weld bead can effectively improve the hardness, the compactness and the tensile strength of the carbon steel substrate, so that the performance requirement of a carbon steel base body after being repaired conforms to re-application. The Fe-Mn-Cu powder core wire and the arc additive processing process thereof are mainly used for fast repairing and remanufacturing key components such as urgent equipment timely and efficiently in a work site or in a field environment.

Description

technical field [0001] The invention relates to the technical field of metal surface processing, in particular to an Fe-Mn-Cu powder core wire material and an arc additive processing technology thereof. Background technique [0002] Wire-arc additive manufacturing (WAAM) is a near-net-shape manufacturing technology that uses arcs as the heat source and inert gases such as argon as the shielding gas, and deposits and deposits filler wire layer by layer. WAAM is a rapid and low-cost manufacturing technology, which is suitable for large-scale and small-batch manufacturing of complex components in aviation, navigation, energy and other fields. [0003] Common arc cladding wires are mainly Fe-based and Ni-based. Arc cladding powder core wire is composed of metal sheath and powder core, so it has the advantages of wire and powder at the same time, broadens the composition and type range of welding wire materials, and meets the needs of multi-functional, diversified and high-perfo...
