Abstract

The manual metallic arc welding of aluminized steel was investigated to determine the suitability of aluminized steel for ship construction from the standpoint of welding. Various electrodes proved capable of depositing porosity-free welds. Preliminary investigation of Grade M plate coated with aluminum alloy K726A (2 1/2% silicon) and welded with low-hydrogen electrodes was more encouraging than that of the Grade M plate coated with 1100 aluminum alloy. Specifically, the welds had considerably more ductility and higher strength, and were free of the extremely hard aluminium-rich compounds Fe2Al5 and Fe2Al3 found in the welds of the 1100 aluminum-coated steel. Additional work is required to confirm these results which would then open the possibility of making successful, tough welds in aluminized plate by modifying the composition of the aluminum alloy coating.
