Tool wear and weld quality characterization in friction stir welding of similar and dissimilar steel

Abstract

The demand for good welding technologies and better weld quality aspects are increasing day by day with the development of advanced materials The study of frictional stir joining of steel has attracted the attention of many researchers during the past two decades due to the wide range of advantages over the conventional fusion welding process Despite the consequence of high process temperature and high stress on tool wear in friction welding of steel alloys the underlying mechanisms involved...
