Effects of Laser Brazing Condition and Filler Metal Composition on Dissimilar Lap Fillet Joint Formation of Austenitic Stainless Steel and Pure Titanium

摘要

Stainless steel features high corrosion resistance but may undergo intergranular corrosion in some specific environments especially in seawater. To cope with this problem, it can be considered to a useful technique to apply titanium material selectively to the part exposed to such specific environments. However, if austenitic stainless steel and titanium are fused together, Fe and Ti create brittle intermetallic compounds, which make it difficult to configure highly reliable joint with suitable welding parameters The authors have studied the laser brazing process to minimize the fusing of the base metals to join the lap joint of stainless steel and titanium.
