Abstract: Engineers today are facing the challenge to join dissimilar materials as they are seeking to create new structures or machine parts in various industries. Problems including porosity formation, solidification cracking, and chemical reaction may arise during fusion welding of dissimilar materials although sound welds may be obtained in some limited cases with special attentions to the joint design and preparation, process parameters and filler metals. Friction stir welding is not more affectable compared with others.
