Harris Products Group, 40436011POP, Aluminum Welding Rod, 1/8 in; 36 in, 1 lb, ER4043, Gray

4043 aluminum GTAW (TIG) welding alloy is an all-position 5% silicon alloy used to weld heat-treatable base metals. It is most often used to weld the 6XXX series of alloys. The silicon addition improves puddle fluidity, producing an appealing bead profile. It is less crack sensitive on the 6XXX series than other welding alloys. It is qualified to AWS A5.10 ER4043, ABS, ISO Designation AlSi5. It is commonly used for welding automotive parts, truck trailers and repairing bicycles. Conveniently packaged for point-of-purchase display.

Applications

• Repair welding of aluminum/cast alloys such as grades 353/A356
• Welding 6XXX series alloys
• Automotive components such as frames, drive shafts, parts, truck trailers
• bicycle frames

Notes

• All parameters are suggested as basic guidelines and will vary depending on joint design, number of passes and other factors.
