The emergence of heavy metal 3D printing technology meets the development needs of large and heavy metal components manufacturing, and has the characteristics of short process, green, and precise digital one-step molding. Additive manufacturing with arc as heat source is a special deposition welding process, which has extremely strict requirements on welding materials. The arc additive manufacturing supporting welding material developed by the iron anchor welding material has the characteristics of low S, P, high toughness, and the physical and chemical properties of the deposited metal are equivalent to or better than the forgings.
Weathering steel is one of the main technical development directions to realize the coating-free anti-corrosion of steel components serving in the atmospheric environment. At this stage, ordinary steel structure bridges mainly use painting to solve the problem of corrosion, but the cost of painting and later maintenance is relatively high; when corrosion-resistant steel is used, it can be used without painting. Welding materials for weathering steel are widely used in bridge construction, and are also widely used in railway vehicle construction, transmission towers and construction fields. The Q355NH, Q420qNH and Q500qNH series of welding materials developed by the iron anchor welding materials have a weather resistance index I of not less than 6.5, and have both excellent mechanical properties and corrosion resistance. They are widely used in China Railway Baoqiao and China Railway Shan Bridge.
Ultra-low hydrogen flux-cored welding wire is based on ordinary flux-cored welding wire, through production process upgrade, formula optimization or other special measures to reduce the diffusible hydrogen content of its deposited metal, so as to reach the high standard welding wire of H5 level. Ultra-low hydrogen flux-cored welding wire provides better joint performance guarantee in the fields of marine engineering, construction machinery, pressure vessels, bridges, etc. Excellent product selection.
COT corrosion-resistant steel supporting welding materials are mainly used for the welding of COT corrosion-resistant steel, which is one of the important components of the construction of oil tank cargo tanks for offshore oil transportation in offshore engineering, including welding rod CJ507NS, flux-cored welding wire YCJ50NS and submerged arc welding wire MJ50NS. According to the corrosion characteristics of the inner bottom plate and the upper deck, different technical solutions are adopted to solve the Cl-pitting corrosion of the inner bottom plate of the cargo oil tank and the hydrogen sulfide corrosion of the upper deck under the crude oil corrosion environment. The weld joint has excellent corrosion resistance, The formation of the ability to provide a series of welding seam materials for different marine corrosion-resistant steels will play a positive role in breaking the technological monopoly of Japan and other countries in this field.
Wuhan TEMO has now formed the industrialization of a full range of high-manganese and low-temperature steel supporting submerged arc welding consumables, flux-cored welding wires, electrodes, and TIG welding wires. , has made positive contributions to the development of the industry in terms of mastering independent intellectual property rights for special products and replacing imports. Our high-manganese steel welding consumables have successfully passed the initial certification of the six countries' classification societies, marking that the anchor has filled the domestic blank of low-temperature high-manganese steel welding consumables for LNG storage tanks. Class society product certification.
