Problems solved by technology

[0002] In the current national standard, there is only 55 kg weather-resistant steel flux-cored wire standard, which has requirements for the content range of various alloy components, including alloy components that have an adverse effect on impact toughness, so the impact toughness of this type of titanium-type flux-cored wire is generally restricted. influences
[0003] However, some weather-resistant steel bridges in severe cold regions require welding consumables to have excellent low-temperature impact toughness and weather resistance. Flux cored wire does not meet the requirements

Description

Technical field [0001] The invention belongs to the field of welding wire production, and in particular relates to a high-toughness titanium type flux-cored welding wire for weathering steel. Background technique [0002] There are only 55 kg weathering steel flux-cored wire standards in the current national standard, which require a variety of alloy components, including alloy components that have an adverse effect on impact toughness. Therefore, the impact toughness of such titanium-type flux-cored wires is generally affected. influences. [0003] Some weather-resistant steel bridges in severe cold areas require welding consumables to have excellent low-temperature impact toughness and weather resistance. Some projects even put forward -60℃ impact requirements for welding consumables. In view of the above practical problems, the current titanium type that meets the national standard The flux-cored wire cannot meet the requirements. [0004] Therefore, the development of a high-to...
