Product description

ER5554 aluminum alloy welding wire is a high-performance aluminum-magnesium alloy welding wire, mainly used for welding 5454 aluminum alloy and other similar materials. Its chemical composition contains about 2.4%-3.0% magnesium, as well as a small amount of manganese, chromium and titanium, which give the welding wire excellent welding performance.

Product Features
Excellent welding performance: stable arc, small spatter, beautiful weld formation, suitable for all-position welding.
Strong corrosion resistance: still maintain good stress corrosion resistance under high temperature conditions.
Good processing performance: has good anodizing color matching, white after oxidation.
Moderate strength: suitable for welding scenarios with medium strength requirements.

Typical application areas
Transportation: automobile wheels, long-distance transport trailers, railway tank cars, etc.
Chemical industry: chemical storage tanks, pressure vessels, etc.
Other fields: refrigeration equipment, shipbuilding, etc.

Specifications and packaging
MIG wire: diameter 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.6mm, etc., packaging weight ranges from 0.5kg to 80kg.
Straight wire (TIG): diameter 1.6mm, 2.0mm, 2.4mm, 3.2mm, 4.0mm, etc.

Welding process
Shielding gas: 100% argon or argon/helium mixture is recommended.
Applicable temperature: Suitable for scenes where the working temperature does not exceed 150°F (about 65°C).

Troubleshooting Porosity Issues with ER5554 Aluminum Welding Wire

Porosity is a common challenge when welding with ER5554 aluminum welding wire, especially in applications like marine-grade aluminum welding or structural aluminum fabrication. Since ER5554 filler wire contains magnesium (2.4-3.0%) for improved strength and corrosion resistance, improper techniques can lead to gas entrapment, resulting in weak welds.

Key Causes & Solutions for Porosity with ER5554 Wire

1. Contaminated Base Metal or Filler Wire
ER5554 welding wire is sensitive to oil, grease, and moisture. Always clean the workpiece with a stainless steel brush and use acetone to remove contaminants.
Best storage practices for ER5554 spools: Keep them in a dry, climate-controlled environment to avoid moisture absorption.

2. Incorrect Shielding Gas Flow
Argon vs. Helium mix for ER5554: Pure argon (100%) is standard, but a 75% Ar/25% He mix improves penetration in thicker aluminum alloy welding.
Optimal gas flow rate: 20-30 CFH (cubic feet per hour). Too low allows air contamination; too high causes turbulence.

3. Improper Welding Parameters
ER5554 MIG welding settings:
Wire diameter | Voltage | Amperage
0.8mm | 18-21V | 90-140A
1.2mm | 20-24V | 150-220A
Pulse welding for ER5554 reduces heat input, minimizing porosity risk.

4. Poor Joint Preparation
Beveling thick aluminum (e.g., 5XXX series aluminum welding) helps prevent incomplete fusion and trapped gas.

FAQ: Quick Troubleshooting Tips
Q1: Why does my ER5554 weld have tiny holes?
A: Likely moisture or contamination—clean the base metal and store wire properly.

Q2: Can I use CO2 shielding gas with ER5554?
A: No—CO2 causes porosity. Use 100% argon or Ar/He mix.

Q3: What's the best wire speed for ER5554 MIG welding?
A: 250-350 IPM for 0.8mm wire; adjust based on amperage.
