Product description

ER5754 aluminum alloy welding wire is a high-performance filler material designed for welding 5xxx series aluminum alloys (such as 5083, 5754, etc.), which complies with the American Welding Society (AWS) A5.10 standard. Its chemical composition is highly matched with the parent material, and it has excellent corrosion resistance and welding processability. It is widely used in shipbuilding, marine engineering, chemical containers and other fields.

Core characteristics
Chemical composition optimization
Magnesium content: 3.0%-3.8% (typical value), ensuring that the strength and corrosion resistance of the weld are consistent with the parent material.
Low iron, low silicon: reduce the negative impact of impurities on weld toughness and avoid thermal cracking tendency.
Mechanical properties
Tensile strength: ≥280 MPa (specific value adjusted according to process).
Elongation: ≥12% (to ensure weld plasticity).
Hardness: HB 80-100, balancing strength and processability.
Corrosion resistance
The weld is resistant to seawater and industrial atmospheric corrosion and is suitable for harsh environments.
Verified by salt spray test (such as ASTM B117), the corrosion rate is less than 5% of the parent material.
Welding processability
Stable arc: less spatter under DC reverse connection (DCEN), beautiful weld formation.
Good molten pool fluidity: suitable for all-position welding (flat welding, vertical welding, overhead welding).

Application scenarios
Shipbuilding
Hull structure, deck, bulkhead welding, meet the certification requirements of classification societies such as DNV and ABS.
Typical cases: aluminum alloy yacht hull splicing, LNG tanker liquid cargo tank sealing welding.
Marine engineering
Offshore platform, oil storage tank, seawater pipeline welding, resist seawater corrosion and stress corrosion cracking.
Chemical and food industry
Corrosion-resistant container and pipeline system welding, in accordance with FDA and ASME standards.
Transportation
High-speed train body and automobile lightweight structural parts welding, taking into account strength and weight reduction requirements.
Architecture and decoration
Aluminum alloy curtain wall, door and window frame welding, ensure smooth appearance and structural safety.

Recommendations for use
Pre-welding preparation
Clean the surface of the parent material (remove oil and oxide film), and make a groove (V-shaped or U-shaped).
Preheat thick plates (>25mm) to 100-150℃ to reduce the risk of thermal cracks.
Welding parameter optimization
Use pulse MIG welding (if necessary) to improve the welding quality of thin plates.
Control the interlayer temperature ≤150℃ to avoid coarse grains.

Post-weld treatment
Grind the weld excess height to the same level as the parent material, and perform X-ray or ultrasonic flaw detection (according to the standard).
Perform stress relief heat treatment if necessary (such as T6 state parent material).

Quality certification and standards
Comply with international standards such as AWS A5.10, ISO 18273, EN ISO 14175, etc.
Provide material certification (MTC) and third-party test reports (such as SGS, TÜV).

More Information About ER5754 Aluminum Welding Wire

What are the advantages of ER5754 aluminum welding wire in automobile manufacturing

High Strength: ER5754 welding wire has a high strength-to-weight ratio, making it ideal for use in automotive manufacturing. It offers superior strength compared to other welding alloys, which makes it a reliable choice for critical components that require maximum strength and durability.

Corrosion Resistance: ER5754 welding wire is highly resistant to corrosion and has excellent resistance to environmental factors such as salt water and harsh weather conditions. This makes it ideal for automotive applications where the vehicle is exposed to harsh environments.

Weldability: ER5754 welding wire has excellent weldability and can be easily welded using a variety of welding techniques, including MIG, TIG, and gas welding. This makes it a popular choice for automotive manufacturing, where a high degree of precision and accuracy is required.

Cost-effective: ER5754 welding wire is relatively inexpensive compared to other welding alloys, making it a cost-effective choice for automotive manufacturers who are looking for a high-quality welding wire that is also affordable.

What are the key considerations when selecting ER5754 aluminum welding wire for marine applications

Corrosion Resistance: Marine environments are highly corrosive, and therefore, the corrosion resistance of the welding wire is a critical factor to consider. ER5754 welding wire has excellent corrosion resistance, making it a suitable choice for marine applications. However, it is essential to ensure that the welding wire is used in conjunction with appropriate welding techniques and protective coatings to prevent corrosion and prolong the lifespan of the component.

Strength: In marine applications, the welding wire must have sufficient strength to withstand the harsh marine environment. ER5754 welding wire has high strength, making it suitable for marine applications where the component must withstand high stresses and loads. However, it is essential to ensure that the welding wire is compatible with the base material to achieve optimal strength.

Weldability: Weldability is a crucial factor to consider when selecting welding wire for marine applications. ER5754 welding wire has good weldability and can be easily welded using a variety of welding techniques, including MIG, TIG, and gas welding. However, it is essential to ensure that the welding wire is compatible with the base material to achieve a strong and durable weld.

Cost-effectiveness: Cost is an important consideration when selecting welding wire for marine applications. ER5754 welding wire is relatively inexpensive compared to other welding alloys, making it a cost-effective choice for marine manufacturers who are looking for a high-quality welding wire that is also affordable.

Compatibility with Protective Coatings: In marine applications, the component must be protected from the corrosive marine environment by applying protective coatings. Therefore, it is essential to ensure that the welding wire is compatible with the protective coating to prevent the coating from delaminating and compromising the protection of the component.

Regulatory Compliance: Marine components are subject to stringent regulations and standards, and it is essential to ensure that the welding wire is compliant with these regulations. ER5754 welding wire is compliant with many marine standards, including ASTM B209 and AWS A5.10, making it a suitable choice for marine applications.
