.... Whether or not the surface seams and decarburization can be tolerated depends largely on the severity of extrusion and the quality requirements of the extruded part. In many applications, acceptable extrusions can be produced with slugs cut from hot-rolled bars. Precision hot-rolled bars have 50% better...

... and by the application of pressure. In basic terms, it is a melting and a forging process. The pieces to be joined are suitably heated by many electrical arcs at the joining interface until the pieces are sufficiently hot to perform an upset, thereby forging the pieces together. The process is capable of producing...
