【Abstract】 Based on the experiments with MTS material testing machine,the characters of the deformationand technology in drawing flux-cored welding wires through conventional dies and roller dies have been analyzed. Experiment data about deformation parameters,force and engrgy parameters,powder flow, lubricating,etal. is obtained.Good foring ability and deformation distribution which decreases drawing force are proposedin roller dies drawing.更多还原
