Abstract
One metallic plate is set upright on another metallic plate and a filler fills each corner formed of both plates. A deposit metal is deposited on and adjacent to each filler to weld the plates to form a recess on that portion to the deposit metal facing a non-welded portion located between the welded plates. Alternatively the recess may be formed by supplying an inert gas to a space formed between the two plates and simultaneously depositing a deposit metal on the plates across the space.
