<p>Composite metal panels comprise two parallel plates (1, 2) each laser-welded to an internally sandwiched corrugated stiffener plate (3). Typically, all the welds (6a, 6b) are in the same sense; firstly, penetrating laser welds (6b) are made along and through the troughs (5) of the corrugations into (or, less preferably, through) an underlying plate (2) and secondly welds (6a) are made along and through an overlying plate (1) along and into or through the peaks of the corrugations (4). Such a panel can be readily fabricated into large-scale metal constructions, especially ships.</p> |
