More Information About ER5154 Al-Mg Alloy Wire Factory

Application of ER5154 aluminum-magnesium alloy welding wire in shipbuilding and welding process optimization

1. Core requirements of shipbuilding for ER5154 welding wire

Material matching:
ER5154 (Al-Mg3.1-3.9%) is compatible with the composition of marine 5083/5086 aluminum alloy parent materials to avoid electrochemical corrosion.

Performance advantages:
High resistance to seawater corrosion (Mg element forms a dense oxide film), low density (lightweight), good low-temperature toughness (applicable to polar ships).

2. Typical application scenarios and cases

Hull structure welding: MIG welding of decks, bulkheads, side plates and other parts.
Special parts: Low-temperature environment welding of liquefied natural gas (LNG) ship storage tanks.
Maintenance field: Repair welding of corrosion areas of magnesium and aluminum parts of the hull.

3. Analysis of welding process difficulties

Oxide film problem:
The Al₂O₃ film (melting point 2050℃) on the surface of aluminum-magnesium alloy leads to the tendency of unfusion, and high-purity argon protection (≥99.99%) is required.

Hot crack sensitivity:
High magnesium content is prone to solidification cracks, and heat input needs to be controlled (recommendation: 80-120A, 20-25V).

Porosity defect:
Sudden change in hydrogen solubility causes pores, and strict cleaning is required before welding (acetone degreasing + stainless steel wire brush treatment).

4. Key measures for process optimization

Parameter optimization:
Pulse MIG welding: frequency 50-150Hz, base current 60A, peak current 180A, reduce heat input.
Multi-pass welding design: interlayer temperature is controlled below 100℃ (to avoid precipitation of Mg₂Si embrittled phase).

Equipment and consumables adaptation:
Use a push-pull wire feeder (such as Fronius push-pull gun), the inner diameter of the conductive nozzle ≥ 1.5 times the diameter of the welding wire.
Protection gas ratio: Ar + 30% He improves arc stability (suitable for thick plate welding).

Quality control:
Non-destructive testing: X-ray flaw detection (porosity ≤ 3%), penetration testing (surface cracks).

5. Comparison of actual application effects

Case data: After a shipyard adopts the optimized process:
Welding efficiency increased by 25% (single-pass welding speed reached 50cm/min);
Weld tensile strength ≥ 290MPa (reaching more than 90% of the parent material);
Salt spray test for 500 hours without pitting (in line with DNV-GL standards).
