Abstract
PURPOSE:To mechanize and automate the work, by detecting the amount of strain of the thin shell plate of the vehicle body, etc., and by controlling the quantity of heat supply correspondingly to the amount of strain for executing the optimum stress relief annealing. CONSTITUTION:The thin shell plate 1 for use of the vehicle body is placed in the vacuum restraining chamber 2, whose inside is then evacuated by the evacuating apparatus 7. The deflection generated in the shell plate 1 by this evacuation is detected by the deflection detector 9. The outout of this detector 9 is inputted to the arithmetic control unit 10, which controls the heating torch moving mechanism 5 so as to vary the moving speed of the heating torch 4. That is, the intensity of the arc generated across the torch 4 and the shell plate 1 is held constant, and the moving speed of the torch 4 is varied; hereby, the quantity of heat supply to the shell plate 1 is suitably controlled. Since the shell plate 1 is supplied with the heat correspondingly to the extent of its strain, the propor stress relief annealing is automatically executed.
