Recently, the production of stainless steel welding material TISCO re-exported to Europe, and the formation of bulk supply for the international high-end welding industry.
Since 2007, TISCO and a well-known international manufacturers to stainless steel welding material welding material needs of the varieties, marketing and product development, etc., both organizations have repeatedly visits, exchange, carried out cooperation talks. According to market demand, TISCO has developed 307 products and high silicon steel 308,309,316 three commonly used high, medium, low silicon welding of stainless steel electrodes and welding wire for the international high-end special requirements for product components, developed a variety of individual users, to form a variety of welding materials, the serialization and brand. With the formation of bulk supply channels, TISCO stainless steel welding material has been successfully into the international high-end welding industry.
Comparison of domestic welding materials manufacturer, TISCO early start of its production, varieties, high purity advantages of steel widely recognized by users. In recent years, TISCO products while maintaining the original characteristics, based on the key projects, key industries, the development of welding materials and have produced a matching stainless steel plate welded rail vehicles sold TCS rod E308L-G, E309L-G, ER308LSi, ER309LSi and other products, these products have been welded using the identification of the domestic rail vehicles, to fully meet user requirements.
Stainless steel electrode is generally divided into: stainless steel, ferritic stainless steel and martensitic stainless steel three. Because the resistance of stainless steel, high thermal conductivity is poor, therefore, compared with the low carbon steel, welding current can be smaller and shorter welding time. Such materials have high temperature strength, the electrode must be high pressure to prevent shrinkage, cracks and other defects. Strong carbon steel welding rod thermal sensitivity, usually shorter welding time, strong internal and external water cooling, and to accurately control the heating time, weld time and weld current, to prevent the heat-affected zone grain growth and the emergence of intergranular corrosion.
Stainless steel welding electrodes recommended Class 2 or 3 electrode alloy in order to meet the needs of the high electrode force.
