What diameter is the Lincoln SuperGlaze 5556 GTAW Aluminum Welding TIG Rod available in, and how do I choose the right size?

TIG filler rod diameter selection: match the rod diameter approximately to the base metal thickness. 1/16 in (1.6 mm) for thin sheet, 3/32 in (2.4 mm) for medium gauge, 1/8 in (3.2 mm) for heavy plate. Using a rod that is too large requires excessive heat to melt the rod and can cause overheating of thin base metal.

What shielding gas should I use with the Lincoln SuperGlaze 5556 GTAW Aluminum Welding TIG Rod?

TIG welding shielding gas selection: use pure argon (99.995% purity) for most TIG applications including steel, stainless, aluminum, and titanium. Helium additions (25–75% He/Ar mix) increase heat input and travel speed for heavy section work and aluminum welding where higher deposition is needed. Never use CO2 or mixed gases designed for MIG welding in TIG torches.

What is the AWS classification of the Lincoln SuperGlaze 5556 GTAW Aluminum Welding TIG Rod?

The Lincoln SuperGlaze 5556 GTAW Aluminum Welding TIG Rod carries AWS ER5556 classification, confirming it meets the American Welding Society's chemical composition and mechanical property requirements for that filler metal category. The AWS classification appears on the rod tube label and verifies the rod's chemistry for code-compliance welding procedures (WPS/PQR).

Q: What is the Lincoln SuperGlaze 5556 GTAW Aluminum Welding TIG Rod used for?

Aluminum TIG rod is used with AC TIG welding on aluminum base metals. ER4043 (aluminum-silicon alloy) is the most common general-purpose choice — it flows well, produces a bright finish, and is compatible with most aluminum alloys. ER5356 (aluminum-magnesium) provides higher tensile strength and is preferred for structural parts and applications that require post-weld anodizing.

Q: How should I store the Lincoln SuperGlaze 5556 GTAW Aluminum Welding TIG Rod to maintain weld quality?

TIG filler rods are typically sold in 36 in lengths in 1 lb, 5 lb, 10 lb, and 25 lb tubes. Store rods in their original sealed tubes in a dry location. Stainless and nickel alloy rods are particularly moisture-sensitive — exposure to humidity can introduce hydrogen and cause porosity or cracking. Never leave opened rod tubes exposed to damp air.
