Dieless drawing process is based on local heating and simultaneously controlled stretching of the workpiece and allows elongation of the workpiece without using a deforming die. This process is usually used for deformation of wires, tubes and bars. The disadvantage of the dieless drawing process is the unevenness of the product diameter along its length. The present paper shows that unevenness can be substantially reduced by dividing the process into several stages. After each stage complete recrystallization of the material must be guaranteed for restoration of plasticity. The value of the strain in each stage must correspond to the area of intensive hardening on the stress–strain curve of the processed material. Thus, the proposed approach is based on the use of the special features of rheology properties of the material. The proposed approach was validated on the example of laser dieless drawing of magnesium alloy tubes.
