From June 27 to 30, the 26th BEW Beijing Essen Welding and Cutting Exhibition (hereinafter referred to as Essen Exhibition) made its grand debut in Shenzhen International Convention and Exhibition Center (New Hall). As a grand event with both scale and influence in the welding field, Essen attracts tens of thousands of professionals from the welding industry at home and abroad every year, and is committed to creating an in-depth exchange platform for the industry and focusing on industrial development. As an innovative welding material enterprise, Bowei Alloy (601137. SH) appeared at booth 8640 of Hall 16, displaying PWHC and HS tin bronze, copper, zinc-copper and other independent innovative lightweight and welding material solutions. During the exhibition, visitors came in an endless stream. In addition, its Beckenhoff (China) Co., Ltd. has received a lot of attention at the booth 16702 in Hall 16 with a variety of welding materials from the aluminum tanker, bicycle, and new energy vehicle industries.
Promote the innovation of welding materials and help the high-quality development
Welding materials are the key conditions to promote the high-quality development of China's welding industry. In the welding process, high-quality welding materials can not only effectively ensure the safety of welding, eliminate impurities in the weld, improve the welding organization, and improve performance, but also as a filler metal, it can fill the groove on the weldment after melting. Form a solid weld. At the same time, high-quality welding materials can stabilize the arc, reduce spatter, improve weld formation, and improve welding process performance. Therefore, the quality of the welding material is very important to the welding.
Bowie Alloy Series Welding Rod Helps Industry to Improve Quality and Efficiency
At this Essen Welding Exhibition, the series of alloy materials exhibited by Bowie Alloy have been deeply applied in rich market practice and continue to function in different scenes. For example, alumina dispersed copper PWHC830 are widely used in resistance welding electrode caps and battery welding needles, which can significantly improve the service life of welding electrodes and help improve production efficiency. The material introduces highly dispersed Al2O3 particles into the copper matrix to hinder the dislocation movement and inhibit recrystallization. Therefore, the high-temperature strength of the product is greatly improved, and the high-temperature softening temperature is as high as 950 ℃. However, the nano-level strengthening phase enables the electrical conductivity of the material to reach above 80% IACS. With excellent mushroom-shaped deformation resistance and anti-adhesion characteristics, the electrode cap is ensured to have more welding points in each grinding interval, thus reducing the grinding frequency and effectively improving the welding life of the electrode cap.
and PWHC850 chromium zirconium copper is widely used in resistance welding in the fields of automobiles, civil appliances and so on. The material is an upgraded version of C18150, with higher temperature softening temperature, higher conductivity and hardness. The material is based on the characteristics of chromium and zirconium elements that the solid solubility changes sharply with the change of temperature at high temperature, and the hardness, strength, electrical conductivity and thermal conductivity are significantly improved by solid solution-aging heat treatment. Excellent cold heading deformation performance, can be cold heading conductive nozzle, anti-adhesion and splash, zinc diffusion resistance, with longer service life and less grinding frequency.
Another welding material PWHC900 has excellent electrical conductivity, thermal conductivity and easy processing characteristics. Its electrical conductivity can reach more than 90% IACS. As the electrode cap material for aluminum body welding, the material can prevent the formation of compounds on the surface of the electrode cap through higher welding current and reduced welding heat generation, thus solving the problem of easy adhesion between the electrode cap and aluminum alloy during aluminum body welding, and greatly improving the service life of the electrode cap for aluminum body welding.
Bowei alloy series welding wire meets the needs of diversified scenes
In addition to welding rods, Bowei alloy welding wire has also attracted attention. In the "Metal Processing" of the "Welding Advanced Technology and Application of Online Forum", Bowei Alloy depth dialogue welding industry experts, brought the automotive lightweight welding solutions. Silicon bronze HS211 can be used for argon arc welding of silicon bronze, copper, brass, copper and steel, and can also be used for surfacing of steel and cast iron, such as friction surfaces of heavy machinery and rolling stock parts, and is more commonly used for argon arc brazing of galvanized steel. Due to the good corrosion resistance of welding materials, less burning loss of galvanized layer and good corrosion resistance of brazed joints, it is widely used in automobile door frames.
In addition, HS216 is widely used for welding and repairing aluminum-nickel bronze castings and forgings, brazing of aluminum-plated thin steel plates and surfacing welding of seawater-resistant steel, and plays a key role in shipbuilding, machinery manufacturing, large equipment manufacturing and other fields. HS218 is widely used for repairing casting or forging base materials of similar composition, and is also suitable for surfacing welding on cast iron and low alloy steel with high corrosion resistance requirements, such as propellers and hydraulic supports. At the same time, L105 manganese brass welding piece, due to the addition of manganese to improve the strength, plasticity and wettability of the brazing filler metal, can be widely used in the brazing of carbide tools, cutting tools and other workpieces, as well as the brazing of oil and mine drill bits.
Beckenhoff (China) series of welding wires, matching welding applications for automobiles, tankers and bicycles
At this Essen exhibition, Beckenhoff (China), a subsidiary of Bowie Alloy, brought berAlweld series of welding solutions. This series of materials have high cladding efficiency and high X-Ray film qualification rate, ensuring stable wire feeding and high production efficiency. They are widely used in new energy vehicles, bicycles, high-voltage switch boxes and aluminum tankers and other industries. At the exhibition, Beckenhoff (China) Chen Xiaojun Chen received an exclusive interview with "metal processing" and described the two advantages and nine technologies of berAlweld series materials. The first major advantage is to meet the needs of customers in terms of welding performance from the mechanism characteristics of the material, which is supported by the four technologies of inert gas protection alloying, online degassing filtration, online grain refinement and three-way Y-type rolling technology. The second major advantage is to meet the application needs of customers in the welding process from the application scenarios of customers, it is supported by five technologies: micro-slip drawing technology (≤ 0.29), surface coating technology, warpage control technology (≤ 0.5cm), light brightening surface treatment technology (Ra≤ 0.4, drawing 100% laser diameter control (≤ 1μm). At the
Essen exhibition, the series of welding material solutions displayed by Bowie Alloy and Beckenhoff fully integrated the technical advantages and industrial needs, providing sufficient guarantee for the upgrading of the welding industry. With the upgrading of equipment and technology, new materials have received more attention. In view of the actual demand, Bowei alloy will strengthen the independent research and development of welding materials, further expand the depth and breadth of welding material application, and continue to create solutions in industries related to the national economy and people's livelihood, such as new energy vehicles, rail transit, shipbuilding, etc., to meet the diversified needs of the market for welding materials, and to forge ahead for the construction of the new development pattern of the national industry.
