EutecTrode-2101

Aluminum Maintenance and Repair Electrode Patented, User-Friendly Electrode for Aluminum Welding

EutecTrode 2101 ®

ELECTRODE • Highly active flux coating • Aluminum-silicon alloy • Good color match with most casting grades

DESCRIPTION:

TYPICAL APPLICATIONS:

EutecTrode 2101 is a flux-extruded electrode for heavy aluminum castings, long joints, defect filling and rebuilding missing sections. This universal aluminum-silicon alloy is excellent for 3xxx and 4xxx series aluminum repairs. It can also be used to weld 1xxx series aluminum. Weld deposits are dense and porosity-free. This user-friendly electrode has a smooth and stable arc. Slag is easily removed after the part has cooled down.

• Engine Blocks • Cast Differential Housings • Various Aluminum Pump Casings • Heavy Gauge Aluminum Truck Bodies • Foundry Patterns • Aluminum Rails

WELDING PROCEDURE & TECHNIQUE: Preparation: Clean weld area to remove contaminants and surface oxides. Parts thicker than 1/8"(3.2mm) should be beveled to have an included angle of 60-75°. Preheat heavy sections or sections thicker than 1/4"(6.4mm) within a 400500°F(204°-260°C) range.

EUTECTRODE 2101 TECHNICAL DATA: Typical Tensile Strength: Typical Yield Strength: Typical Hardness: Electrical Conductivity: Color Match Properties:

34,000 psi (235 N/mm2) 28,000 psi (190 N/mm2) BHN: 45 IACS%: 39 Good, but will darken after clear anodizing

WELDING PARAMETERS: NOTE: Preheating reduces the need to use high amperage levels.

Technique: Start arc either by lightly drawing the electrode across the work piece or use a copper starting block. To help control the arc response, it is important to maintain a very short stand-off distance and to keep the electrode almost perpendicular. Back-whip craters and allow to cool before de-slagging.

Post-Welding: Slag removal is very important. It can become corrosive if not removed. Scrub in hot, soapy water then rinse.

DCEP (+) 1/8" - 3.2mm 90 - 140

HEALTH AND SAFETY: Observe normal welding practices, respiratory protection and proper air flow pattern advised. For general welding practices, see AWS publications Z49.1 “Safety in Welding and Cutting and Allied Process”. Welding is a completely safe process when performed in accordance with proper safety measures. Become familiar with local safety regulations before beginning welding operations. DO NOT operate welding equipment or use welding materials before you have thoroughly read the proper instruction manual(s).

Please refer to the Eutectic internet site for Material Safety Data Sheet (MSDS) information.
