Özet
Solid-state bonding or extrusion welding takes place during hot extrusion of hollow shapes. The weld integrity is critical for mechanical performance of the produced profiles. To evaluate the weld integrity, a novel modeling method using DEFORM (TM) was proposed by Xu and Misiolek (2011) and modified in the present study. Metallurgical analysis of extruded magnesium alloy AM30 revealed two types of extrusion weld seams. The first seam type does not show a weld line which indicates perfect solid state bonding, and the second type contains a weld line, which could be a potential source of imperfections in the extrudate.
