New progress of the convergence on Japanese weldin

The new standards of welding materials and submerged arc welding fluxes for low alloy heat-resistant steel in Japan are in line with international standards. Welding materials for heat-resistant steel include electrode, flux cored wire, filler wire and solid wire, which are suitable for shielded metal arc welding, MAG welding, MIC welding, TIG welding and submerged arc welding. Flux for submerged arc welding is not only suitable for joint welding but also for surfacing welding. The applicable steels include low carbon steel, high strength steel, chromium molybdenum steel, low temperature steel, stainless steel, heat resistant steel, nickel and nickel alloy, etc. The surfacing method is suitable for both wire electrode and strip electrode, and the surfacing layer is suitable for wear-resistant or corrosion-resistant surfacing.

The current situation of international standard sy

As an effective means to lead the technical progress of the industry and promote the improvement of product quality, standardized t-work is increasingly attracting the attention of the government and industry. In recent years, significant changes have taken place in the international welding material standards. As the largest and most authoritative international standardization organization in the world, the international organization for Standardization (ISO) has successively completed a series of revision of welding material standards, forming a relatively complete standard system. European welding material standard (EN) is basically consistent with the a system of ISO welding material standard, and many standards directly refer to ISO standard. At present, the United States undertakes the function of ISO / tc44 / SC3 Secretariat and plays an important role in ISO t work. The B system of ISO welding material standard is based on American AWS standard. At present, Japan is actively integrating and transforming its own standards according to ISO welding material standards. Therefore, by understanding the current situation and development trend of the main international welding material standards, timely revising the welding material standards in China will have a far-reaching impact on the development of domestic welding materials.
