The opening chapter provides a comprehensive insight into dissimilar materials joined by FSW technology. FSW parameters such as tool design, tool pin offset, rotational speed, welding speed, tool tilt angle and position of workpiece material in the fixture for dissimilar materials are summarized. In the next chapter the author confirms the emission of particles in the nanorange during FSW of the most commonly used aluminium alloys, AA 5083 and AA 6082, which are originated from the aluminium alloy itself, due to friction of the welding tool against the workpiece. In the closing chapter,...

Provides thorough coverage of resistance spot welding fundamentals and principles. Topics covered include lobe and current range curves, contact resistance vs. electrode force, dynamic resistance, heat balance, nugget growth, etc. Equipment issues such as machine types, power supplies, and electrodes are addressed. Spot welding challenges to modern automotive manufacturing is also covered.

In friction stir welding (FSW) of two similar or dissimilar metals, the work materials are positioned in such a way against a rotating-travelling stirring tool that allow FSW operations to be performed. The operation is begun by pushing the bottom of rotating tool pin against the initial position of weldment to be produced along desired welding line. The push by the bottom of rotating tool pin on the surface of work materials to be welded is made in order to generate local heating by mechanical friction. This book examines the weldment formation in friction stir welding.
