NARROW GAP WELDING OF HIGH-STRENGTH STEEL
The David W. Taylor Naval Ship Research and Development Center (DTNSRDC), in conjunction with industry, has developed an automated narrow-gap welder for thick plate ship construction which can reduce welding time and cost by as much as 50 percent. Compared to conventional processes, automated narrow-gap welding utilizes a simpler, less expensive joint preparation, fewer welding passes and less filler metal, with reduced distortion in completed welds. The equipment has been successfully used in fabricating 2-in thick HY-80 narrow-gap weldments in lengths approximating those used in production. These weldments compiled with Navy specification requirements, verifying the reliability of the equipment and the process for manufacturing.
