Problems solved by technology

However, the existing domestic underwater welding materials, such as TS203 and other underwater welding rods, have low strength, only about 400Mpa, which is difficult to meet the underwater welding requirements of high-strength steel, and foreign materials are generally required for engineering.

Abstract

A high-strength wet welding electrode for underwater welding is composed of the core made of H08E steel wire a coated surficial water-proof layer, and a coated sandwich layer containing rutile (42-54 Wt%), potash feldspar (12-20), talc (6-14), cellulose (4-12), ferromanganese (6-14), Ni powder (0-4), Fe powder (3-12) and at least one kind of Nickel powder (2-4) and Al-Mg alloy (2-4).

Description

Technical field [0001] The invention belongs to welding materials and mainly relates to a high-strength underwater wet welding electrode. Background technique [0002] Underwater wet welding has many advantages such as simple equipment, low cost, high construction efficiency, and low cost. A variety of welding materials have been developed at home and abroad. In order to adapt to the underwater welding of high-strength steel, corresponding underwater welding materials have been developed abroad, such as 7018'S in the United States, HydroweldFS in the United Kingdom, etc. The HydroweldFS electrode in the United Kingdom is produced by Poseidon Corporation, with specifications of φ3.2mm, φ4 .0mm, φ5.0mm, model AWSE6013, welding rod strength above 470Mpa, good welding process performance. However, the existing domestic underwater welding materials, such as TS203 and other underwater welding rods, have low strength, only about 400Mpa, which is difficult to meet the underwater welding...
