Under the background of double carbon target, hydropower, as a rich and lasting clean energy, has broad development prospects. The turbine runner is the heart of the hydropower unit, and its welding quality is directly related to the safety and reliability of the unit operation. The welding of large-scale runner at home and abroad uses the same material of martensitic stainless steel welding material.
Harbin Weir Welding Co., Ltd. independently developed low alloy high strength steel solid gas shielded welding wire HS-70, suitable for welding low alloy steel with yield strength of 550 ~ 690Mpa. It is the earliest independent research and development of high-strength steel welding wire products in China. It has more than 30 years of engineering application experience and has been applied in many major projects in China. It is suitable for welding of bridges, petrochemical industry, engineering machinery and commonly used medium carbon tempered steel and cast steel structures with corresponding strength level requirements.
Low alloy high strength steel with yield strength of 690MPa is widely used in large-scale engineering machinery manufacturing, marine engineering and hydropower engineering. However, in major projects and key welds, most of the welding materials rely on imports. In order to solve this problem and accelerate the realization of localization, Harbin Weir Welding Co., Ltd. has transformed years of technological research and development results into products and successfully developed HS-80 solid gas shielded welding wires, which are suitable for welding bridges, steel structures and construction machinery with corresponding strength requirements.
In recent years, with the continuous emergence of major engineering projects, the requirements for the use of low-alloy high-strength steel are getting higher and higher. While the carrying capacity continues to increase, it must also meet the needs of lighter weight and more efficient. Therefore, 1000MPa Grade high-strength steel is increasingly used by large construction machinery manufacturers. The HS-96 solid gas shielded welding wire developed by Weir Company has met the engineering needs and is suitable for welding bridges, steel structures and construction machinery with corresponding strength requirements.
Harbin Weir Welding Co., Ltd. nickel-based 600 alloy welding series welding materials include SAW NiCr-3/SJ608 wire submerged arc welding, ENiCrFe-2 electrode and ERNiCr-3 wire. Suitable for welding Inconel600/601 alloy, Incoloy800/800H alloy, can be used for steel surface surfacing. The welding material is widely used in the welding of dissimilar metals, such as Inconel alloy, Incoloy alloy, Monel alloy, carbon steel, low alloy steel and stainless steel. At present, it has been widely used in the welding of pressure equipment, heat treatment equipment, petrochemical, clean energy equipment, etc.
The corrosion-resistant lining of the inner wall of pressure vessel equipment such as petrochemical industry, coal chemical industry and boiler needs large-area surfacing stainless steel. For a long time, based on reliability, double-layer surfacing welding method has been selected. The efficient and fast single-layer surfacing welding method has high process requirements and technical difficulties. Surfacing materials have been dependent on imports. After years of research and development, Harbin Weir Welding Co., Ltd. has developed single-layer electroslag stainless steel strip surfacing materials: welding strip H308LF and flux SJ15F, which replace double-layer strip surfacing welding and have been applied to surfacing welding on the inner wall of domestic pressure vessels.
The corrosion-resistant lining of the inner wall of equipment such as hydrogenation process equipment and coal chemical pressure vessels in oil refining and petrochemical industries requires large-area surfacing stainless steel. For a long time, based on reliability, double-layer surfacing welding method has been selected. Efficient and fast single-layer surfacing welding method has high process requirements and technical difficulties. Surfacing materials have been imported. After years of research and development, Harbin Weir Welding Co., Ltd. has developed single-layer electroslag stainless steel strip surfacing materials: welding strip H316LF and flux SJ15F, which replace double-layer strip surfacing welding and have been applied to surfacing welding on the inner wall of domestic pressure vessels.
The corrosion-resistant lining of the inner wall of the equipment in the hydrogenation process device in the oil refining and petrochemical industries requires a large area of surfacing stainless steel. For a long time, based on reliability, double-layer belt-pole surfacing method has been selected. The efficient and fast single-layer belt-pole surfacing method has high process requirements and great technical difficulty. The surfacing materials have been dependent on imports. After years of research and development, Harbin Weir Welding Co., Ltd. has developed single-layer electroslag stainless steel strip surfacing materials for hydrogenation units: welding strip H347LF and flux SJ15F, which replace double-layer strip surfacing and have been applied to surfacing welding on the inner wall of domestic hydrogenation reactors.
