Abstract：

A new correction process which can make sheet metals thermoplastic deformation without dies through the use of a laser as a heat source was described. The summary of the present situation at home and abroad was given in the laser correction. The possible application was suggested on the basis of current study status and the research that had been done on the sheet metal forming and laser heat processing. The feasible experiment was done. The factors influencing on laser correction were analyzed. The research direction was discussed.
