Short time resistance spot welding of 1.2Gpa ultra-high strength steel using high frequency power supply
AbstractThe task of 1.2 GPa ultra-high strength steel sheet in short time’s high current spot welding has been clarified. High current and short time spot welding system and high frequency power supply has been developed. In order to prevent spatter, new dual-pulse welding method in which primary energization, cooling and secondary energization has been proposed. By using this novel welding method, nugget diameter and tensile shear strength satisfied the target and spatter did not occur. New method of 1.2 GPa ultra-high strength steel sheet in short time and high current spot welding has been established.Keywords: Resistance spot weldingultra-high strength steelspattertensile shear strength Additional informationFundingThis research was commissioned by the New Energy and Industrial Technology Development Organization (NEDO) under the auspices of the Institute of Structural Materials for Advanced Materials (ISMA) of the New Energy and Industrial Technology Development Organization (NEDO).
期刊介绍：
Welding International provides comprehensive English translations of complete articles, selected from major international welding journals, including: Journal of Japan Welding Society - Japan Journal of Light Metal Welding and Construction - Japan Przeglad Spawalnictwa - Poland Quarterly Journal of Japan Welding Society - Japan Revista de Metalurgia - Spain Rivista Italiana della Saldatura - Italy Soldagem & Inspeção - Brazil Svarochnoe Proizvodstvo - Russia Welding International is a well-established and widely respected journal and the translators are carefully chosen with each issue containing a balanced selection of between 15 and 20 articles. The articles cover research techniques, equipment and process developments, applications and material and are not available elsewhere in English. This journal provides a valuable and unique service for those needing to keep up-to-date on the latest developments in welding technology in non-English speaking countries.
