1. A welding tool for a robot that welds together a first component made of a first metal and a second component made of a second metal by using a metallic welding element disposed within a through-hole provided in the second component, the welding tool comprising:
a welding torch attached to an arm of the robot;
a supporter attached to a distal end of the arm and capable of holding the metallic welding element before being disposed within the through-hole;
an element holder that is provided with a plurality of claws and that receives the metallic welding element held by the supporter to hold the metallic welding element in a state in which the metallic welding element is not disposed within the through-hole; and
a component pusher, wherein the component pusher comprises a member attached to the distal end of the arm so as to be movable in an axial direction of a distal end of the welding torch and a motor that moves the member in the axial direction,
wherein the element holder disposes the metallic welding element between the welding torch and the through-hole and disposes at least a part of the metallic welding element within the through-hole.
