Cryogenic Service Aluminum Welding Wire

Advantages

• Guaranteed Low-Temperature Toughness: The weld metal retains high impact strength and ductility, preventing brittle failure in severe cold environments.

• High Integrity: Low-hydrogen and high-purity processing minimize porosity and defects, essential for pressure vessel certification.

• Excellent Mechanical Strength: Delivers superior tensile and yield strength in the as-welded condition, critical for structural safety.

• Certified Consistency: Every batch is manufactured under strict control to ensure uniform properties required for code-stamped vessels.

FAQ

• Q: What is the primary concern when selecting a filler metal for cryogenic service?
• A: The main concern is ensuring the weld metal does not undergo a ductile-to-brittle transition at low operating temperatures, which requires filler alloys with low impurity content and specific Manganese/Magnesium levels.

• Q: Is ER4043 recommended for cryogenic applications like LNG?
• A: No, ER4043 and other Aluminum-Silicon fillers are generally unsuitable as they lose significant ductility and toughness at cryogenic temperatures. High-Magnesium alloys like ER5183 are the industry standard.
