The bending method based on friction-stirring welding thechnology for aluminum alloy extrusion bar

摘要

The present invention provides an aluminum alloy extrusion processing to the banding around, rubbing the tensile expected part of the process when banding By applying stir welding technique, one to improve the bending workability of the aluminum alloy extruded material, to a bending processing method of an aluminum alloy extruded material using the friction stir welding technique. ; The method of the present invention, Tensile expected part of the selection process and during the banding; And welding head close to tension the expected negative phase one end surface; And steps to push forward the weld head rotation and at the same time, a tensile expected heating; Made by the extrusion process steps, such as banding. ; Bending of aluminum alloy extrusion processing method using friction stir welding techniques of the present invention is expected to improve the bending process productivity significantly reduce the failure rate with the banding process, is.
