Welding device

Abstract

A welding device includes: a heating element made of a fiber-reinforced resin in which fibers are arranged in one direction, the heating element disposed between a first workpiece and a second workpiece; a plurality of systems of electrodes attached to the heating element, the plurality of systems of electrodes dividing an energized region of the heating element in a direction intersecting an extending direction of the fibers; a power supply device that applies current in the extending direction in the heating element by applying a voltage to the electrodes; and a pressurizing device that welds the first workpiece and the second workpiece via the heating element by applying a pressure to at least one of the first workpiece or the second workpiece in a direction in which the first workpiece and the second workpiece approach each other in a state where the heating element has generated heat.
