ED034177 - Lincoln SuperGlaze 5556 Aluminum TIG Rod 3/32" (10lb)

High-Performance Aluminum Alloy TIG Filler Metal

The Lincoln Electric SuperGlaze® 5556 TIG (GTAW) Rod is a specialized aluminum welding consumable engineered for applications demanding exceptional tensile strength and ductility. Identified by the AWS classification ER5556, this rod is formulated from an Aluminum-Magnesium-Manganese alloy containing small amounts of Zinc and Titanium. It is specifically designed to weld high-strength 5XXX series base materials, such as 5083 and 5456, which are commonly used in the fabrication of pressure vessels, storage tanks, and heavy structural components. The 3/32-inch (2.4mm) diameter provides optimal control for manual TIG welding, allowing for precise bead placement and heat management.

Technically, the 5556 alloy offers distinct mechanical advantages over the more common 5356 or 5183 filler metals. The specific alloying elements refine the grain structure and enhance the load-bearing capacity of the weld deposit, making it the preferred choice for critical structural joints. Additionally, SuperGlaze 5556 exhibits outstanding corrosion resistance, particularly in saltwater environments, which establishes it as a standard consumable in the shipbuilding and marine repair industries. It maintains its mechanical properties well in the as-welded condition, ensuring the integrity of the assembly under stress.

Lincoln Electric employs proprietary manufacturing processes for the SuperGlaze line to ensure superior surface cleanliness and diameter consistency. This rigorous quality control minimizes the presence of surface oxides and hydrogen-containing contaminants, significantly reducing the risk of weld porosity. For the welder, this translates to a stable arc, smooth metal transfer, and a clean weld puddle that is easier to manipulate. The rods are packaged in a durable 10 lb carton to protect against environmental moisture and physical damage during transport and storage.

In terms of compatibility, while optimized for 5XXX series alloys, the SuperGlaze 5556 is also effective for welding 6XXX series base metals when higher weld strength is required than what 4043 can provide. It is also an excellent choice for applications requiring post-weld anodizing, as the alloy composition provides a close color match to the base metal, avoiding the dark gray discoloration often associated with high-silicon fillers. Proper storage and handling are recommended to maintain the rod's premium condition prior to use.
