PROBLEM TO BE SOLVED: To improve welding quality by optimizing welding of first and second heaters regardless of a temperature difference between the first and second heaters caused by the movement of a carrier.SOLUTION: A welding apparatus includes: a temperature sensor 13 for detecting the temperatures of the first heater 11a, 11b and the second heater 12a, 12b at the time when a handler 8 holding a first sheet 4a moves in the vertical direction; and a control device 15 which controls a moving mechanism 9. The first heater 11a, 11b and the second heater 12a, 12b are vertically movably installed. The control device 15 adjusts welding times of the first heater 11a, 11b and the second heater 12a, 12b by controlling the movement of the handler 8 in the vertical direction on the basis of the temperatures of the first heater 11a, 11b and the second heater 12a, 12b detected by the temperature sensor 13. |
