| Abstract: | The neck-spinning process is used to make square tube into circular section. It is simulated by using Abaqus software to analysis the stress and strain distribution, variation of wall thickness, changes in axial length and load change during the forming process. The forming defects are also discussed. At last the process is optimized. Experimental results demon-strate the possibility of the forming process and desired effects are got. |

| Keywords: | neck-spinning numerical simulation square tube stress-strain variation of wall thickness |
