ALUMINUM IN SHIP AND BOAT BUILDING

Following a comparison of the mechanical properties of various marine aluminum alloys with those of steel, the Author discusses some general design considerations. Examples are given of the use of extrusions to reduce the amount of welding and fitup time. Methods of cutting and working aluminum are briefly reviewed. The introduction of plasma arc cutting has resulted in significant savings in time and cost. For most shipyard applications MIG-welding is used. The main features of the various equipments available are compared. Problems of distortion can be overcome by careful construction methods. In general, correction is better achieved by additional welding than by flame heating. Finally, it is emphasised that, in order to obtain the maximum advantage from the use of aluminum, it is better to start from first principles rather than to develop procedures from equivalent steel practice.
