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
