In a spray process, it is comfirmed that a temperature of residual stress'es generation has to be clarified for mechanism in generation of residual stress. But a mechanism of the temperature is largely-unexplored. And so in this report an estimation approach of residual stress is proposed through the viewpoint of energy consumption. By measurements of a surface temperature, a base temperature and a residual stress for 1 sample, a parameter for presuming a temperature of residual stress 'es generation is clear up. And residual stresses of other samples are presumed reasonably with the finite element analysis of thermal stress. Accordingly, it is clear up that the proposed estimation approach is reasonable. Based on the estimation approach, the control approach of residual stress is established. In addition, flowchart for residual stress'es control in product is presented. Accordingly, residual stress can be controlled reasonably.
