This treatise discusses economic effects of various methods for promoting automation of welding in shipbuilding by calculating welding arcing time for ship construction. From the viewpoint of economy, the automation of welding is one of the most imperative requirements now imposed on the shipbuilding industry. In most of the cases so far, the automatic welding has found its application only in the fabrication work on the assembly ground of flat panels contained in the cargo part of a ship. A ship, however, inevitably must take a streamlined shape since it travels in the water, a fluid. Hence, there exists curved part at the bow and stern of it. Further, the welding work on the building berth as a whole amounts to about 40 percent of the total welding work with respect to the required man-hour. In view of the above, the authors discuss here, (1) automatic welding of the curved shell plate as well as of the flat panel on the ground, (2) actual measures of automation of welding on the berth and (3) the economic effects to be achieved thereby.
