Notes:
A method for joining metals in the semisolid state is presented. A model alloy Sn-15%Pbwas used to demonstrate the concept. By presented process, dendritic microstructure of the weldzone can be avoided. Moreover, near-weld zone of the cold worked substrates which is affected byheat would have a globular structure due to a thermomechanical treatment. The two substrates wereheated up locally in the joint line to the semisolid temperature range. At this point a stirrer wasintroduced into the weld seam in order to mix the two sides into a single uniform joint. Localizedmechanical properties of different zones were examined using Shear Punch Test (SPT), showing agood strength in the weld zone and thermomechanically affected zone
