Abstract
Temperature in the vicinity of a heated point on a work ( ) surface on a moving locus of flame poured from a torch ( ) is measured, the measured value is inputted into a controlling unit ( ). It is converted into a physical quantity which appeals to the perception of a worker, such as light, sound, or vibration, and outputted to warning means ( and ). The measured value is compared with a predetermined standard temperature range, and as the measured value approaches the upper limit or the lower limit of the standard temperature range, the physical quantity produced as warning signal is stepwise changed. This permits the worker to perceive the change in the measured value, and to easily change the position of the torch or the moving speed thereof so that the temperature at the heated point is maintained within the standard temperature range. Also, recording the measured values of the heating temperatures by connecting a recording unit ( and ) to the controlling unit ( ), can serve to quality control.
