PRELIMINARY EVALUATION OF DIRECT-CURRENT MANUAL WELDING OF 2014-T6 ALUMINUM,
Abstract
Roark Engineering d-c welding is only equal or inferior to Martin a-c welding; Direct-current filler-arc welding holds considerable promise over a-c welds because: The weld heat-affected zone decreases noticeably, using either 4043 or 5456 aluminum filler rods; Weld strengths are equal or superior under the same conditions; Using 5456 filler rod, a finer grained weld structure and higher initial weld hardness are achieved. (Higher hardness and finer grain structure could cause weld cracking problems.) (Author)
