High-performance rutile carbon steel welding rod

Abstract

The invention provides a high-performance rutile carbon steel welding rod. The welding rod comprises a welding core and a cover; and the cover comprises the following components in parts by weight: 45-55 parts of rutile, 10-25 parts of quartz, 10-20 parts of marble, 5-15 parts of medium-carbon ferromanganese, 5-15 parts of kaolin, 2-12 parts of microcrystalline cellulose, 2-8 parts of starch, and1-5 parts of titanium dioxide. In the high-performance rutile carbon steel welding rod and a preparation method thereof, the welding rod achieves excellent comprehensive mechanical performances and reliable cracking resistance, the formation of a welding bead is improved, the welding splashing and the smoke harm are reduced, the generation process of the welding rod is simplified, the quality of the welding rod is stabilized, and high carbon steel welding requirements are met.

Description

technical field [0001] The invention belongs to the technical field of welding rod production, in particular to a high-performance rutile carbon steel welding rod. Background technique [0002] With the development of welding technology, higher and higher requirements are put forward for the quality of welding materials. my country will produce millions of tons of low-carbon steel electrodes every year, mainly titanium-calcium-type general-purpose electrodes, which are used to support my country's infrastructure construction. However, due to the limitation of the acidity and alkalinity of the slag oxide of the electrode itself, the comprehensive mechanical properties of the deposited metal of the general-purpose titanium-calcium carbon steel electrode are not good, and the anti-cracking performance of the electrode is unstable. At the same time, during the use of titanium-calcium-type carbon steel electrodes, because there are too many organic substances in the coating, a l...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the acidity and alkalinity of the slag oxide of the electrode itself, the comprehensive mechanical properties of the deposited metal of the general-purpose titanium-calcium carbon steel electrode are not good, and the anti-cracking performance of the electrode is unstable.

At the same time, during the use of titanium-calcium-type carbon steel electrodes, due to too much organic matter in the coating, a large amount of smoke and dust are generated, which is easy to cause environmental pollution and cause harm to the welder's body

Moreover, the welding process performance of titanium-calcium-type carbon steel electrodes such as welding bead formation, welding spatter, and welding operability are relatively common, and there is a lot of room for improvement.
