PROBLEM TO BE SOLVED: To permit an urgent treatment of an electric fusion welding joint, in which a bar code can not be read, by a simple inputting operation without rendering a worker at site conscious of expert parameters, such as the control information (a fusion welding condition such as a voltage and an energizing period of time) of the electric fusion welding joint. SOLUTION: A label A, given by numerical information A2 minimally necessary for the control of fusion welding heating, is bonded on the surface of an electric fusion welding joint S different from a bar bode A1 while an electric fusion welding device 1 is provided with numerical information coping data table 19c, storing the numerical information A2 while coping with a necessary information for the control of fusion welding heating, and an inputting unit 14 for inputting the numerical information A2. When the numerical information A2 is inputted from the inputting unit 14, a CPU 3 reads out a necessary information for the control of the fusion welding heating coping with the inputted numerical information A2 from the numerical information coping data table 19c and a fusion welding power supply is supplied to the electric fusion welding joint S based on the read fusion welding heating control information. |
