Welding rod with high rust resistance

Abstract

The invention discloses a welding rod with high rust resistance. The welding rod comprises a core wire and a welding rod covering and is characterized in that the core wire is an H08A rolled steel wire; the welding rod covering comprises the following raw materials in part by weight: 30-40 parts of marble, 15-20 parts of fluorine, 4-6 parts of ferromanganese, 5-7 parts of ferrosilicon, 3-6 parts of ferrotitanium, 15-20 parts of iron powder, 4-7 parts of rutile, 1-3 parts of mica, 1-3 parts of silica fume and 0.2-1 part of magnesium powder. After the welding rod disclosed by the invention is stored in a moist environment or exposed in the air for a long time, no rust phenomenon of the core wire occurs; the storage period of the welding rod is prolonged; the quality of products is improved; and the welding rod has favorable and high rust resistance.

Description

technical field [0001] The invention belongs to the technical field of welding material preparation, and in particular relates to a welding rod with high corrosion resistance. Background technique [0002] With the progress of science and technology and the development of industrialization level, new welding methods and welding materials are constantly appearing, but manual arc welding is still the most basic welding method in various industrial fields due to its convenient use and wide application range, while manual arc welding The welding rod used still occupies the first place among all kinds of welding materials. [0003] The welding rod is composed of two parts, the coating and the welding core. When the welding rod is stored in a humid environment or exposed to the air for a long time, the welding core will be obviously rusted. This phenomenon is very obvious especially in spring and summer, and autumn Basically no in winter, users will question the performance of th...

Problems solved by technology

[0003] The welding rod is composed of two parts, the coating and the welding core. When the welding rod is stored in a humid environment or exposed to the air for a long time, the welding core will be obviously rusted. This phenomenon is very obvious especially in spring and summer, and autumn Basically no in winter, users will question the performance of the product after corrosion occurs and refuse to use it. At the same time, the quality of welding rods is also affected. The storage period of welding rods is short, which affects the storage and performance of welding rods. This problem has always plagued welding materials. Manufacturer
