Course Description

This course discusses the importance of alignment, how to: correct soft foot, check runout, align two pieces of rotating machinery using dial indicators, and to review all the currently used alignment equipment and techniques (e.g. lasers and electromechanical systems).  It also discusses the types of shaft misalignment
