EutecTrode-3021

Aluminum Maintenance and Repair Electrode

EutecTrode 3021 ®

ELECTRODE • Aluminum-silicon alloy • Combat alloy • Good color match with most aluminum casting grades

DESCRIPTION:

TYPICAL APPLICATIONS:

EutecTrode 3021 is a combat version of EutecTrode 2101.

This electrode can be used to weld heavy aluminum castings, long joints, defect filling and rebuilding missing sections. It can also be used for welding extrusions, piping, furniture as well as aluminum castings containing manganese and/or silicon. 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.

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 400-500°F (204°-260°C) range.

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.

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.
