1. A method of forming a welded structure comprising:
- arranging constituent pieces of the structure to be welded on a support surface in a desired configuration, recording at least one extended two-dimensional image of the arrangement of the constituent pieces on the support surface, determining the positions of a plurality of weld points by viewing the two-dimensional image(s), receiving a user input that specifies a welding method for each weld point, welding with welding apparatus the constituent pieces together at said weld points in accordance with the respective specified welding methods to form the welded structure, and controlling the welding of the constituent pieces with said welding apparatus on the basis of the determined positions of the weld points.

Abstract
Constituent pieces of a structure to be welded are arranged in a desired configuration on a support surface and are welded together at a plurality of weld points to form the welded structure. At least one image of the arrangement of the constituent pieces on the support surface is recorded and the positions of the weld points are determined from the image(s). The welding of the constituent pieces is controlled on the basis of the determined positions of the weld points.
