Abstract
The aim of this study was to improve extrudability limit, eliminate welding line and obtain
optimum thixoextrusion conditions for manufacturing tubes of 7075 Al wrought alloy. By
thixoextrusion, it was possible to improve deformability, control isotropy with extrusion direction,
eliminate welding line (seamless) and save cost due to low energy consumption compared with
conventional extrusion processes. The welded part was not observed at the welding line area. The
grains of thixoextruded tube were homogeneously distributed and equiaxed grains were observed.
Therefore, thixoextrusion is the most effective variable for the control of the magnitude of the
welding line.
