Abstract
A plate body is formed from two plane metal plates each at least 5 mm thick and having an edge at least 10 meters long, by machining each plate along its edge to form a welding groove with high accuracy relative to the dimensions and shape of the groove and with a smooth groove surface. The groove extends from a first side of each plate through only part of the thickness of the plates to leave a root area at the second side of the plate. The plates are supported in the vicinity of the welding groove from the second side of the plates by a support bed and are retained by use of suction in relative positions such that the root areas of the two plates are in confronting and contacting relationship. A weld is created in the welding groove by butt joint welding from the first side only of the plates.
