1. A tool for welding a light pane to a housing of a motor vehicle light, the tool comprising:
a base body; and
at least one heating element arranged on the base body,
wherein the heating element is displaceable relative to the base body between an idle position and a heating position,
wherein the base body has a substantially plate-shaped design with a bottom side, wherein a z-direction is defined by the surface normal of the bottom side and an x-direction is defined by a tangent to the bottom side, and wherein the heating element is arranged on the bottom side and is linearly displaceable in a displacement direction, wherein the displacement direction corresponds to the x-direction, or wherein the projection of the displacement direction onto the x-direction and onto the z-direction has non-vanishing components, and
wherein the bottom side of the base body has an inclined partial surface, wherein the projection of the surface normal of the partial surface onto the x-direction and onto the z direction has non-vanishing components, and wherein the heating element is accommodated on the inclined partial surface.
