Summary:

Weldable vibration damping steel sheet consists of two skin steel sheets and viscoelastic resin film that contains filler metal powder to get electric conductivity. In this study, it is investigated the effect of filler powder (type; size and content) on weld defects.The defects are observed when the resin layer is thick comparing with the powder diameter or the content of metal powder is insufficient.The defect with bare skin sheets which is spherical hole is caused by joule overheating. Another defect is observed when Zn-Fe coated skin sheets are used. According to the observation of welding current and voltage wave forms. It is formed by an arc electric discharge between metal powder and skin sheet, which is caused by cutting off current paths due to the evaporation of Zn-Fe coated layer.Based on these results, it is determined the suitable filler powder to produce VDSS with good weldability
