Lap welding of titanium and mild steel sheets by seam welding

Abstract

Titanium, a metal with superior sea water corrosion resistance, is increasingly used in titanium clad steel applications for ocean structures. Titanium clad steel is normally manufactured by hot rolling or explosive deposition. Joining of titanium and iron leads to the formation of hard and brittle intermetallic compounds that impair the bond strength. It is therefore necessary to use an insert metal to suppress the occurrence of these compounds, particularly during rolling.^1–3
