Welding Electrode, Aluminum

This aluminum welding electrode is designed for welding all aluminum and aluminum alloys in any position. It can also be used as a torch brazing alloy, making it highly adaptable for repair and maintenance applications.

Suitable for cast, wrought, and extruded aluminum components, it offers stable performance and reliable weld quality.

Technical specifications:

• Tensile strength: approx. 41 PSI
• Alloy composition: Aluminum / Silicon (AlSi)
• Current type: DC constant current, reverse polarity
• Application: Welding and torch brazing

Recommended amperage:

• 2.5 mm (3/32"): 50–80 A
• 3.2 mm (1/8"): 70–120 A
• 4.0 mm (5/32"): 110–150 A

Welding techniques:

• Clean thoroughly (remove oil, grease, and oxide)
• Wire brush and grind the weld area
• Chamfer edges and open cracks before repair
• Preheat thicker sections
• Start with higher amperage and reduce as heat builds
• Use fast travel speed and steady feed
• Restart welds by welding into previous crater

Typical applications:

• Truck beds, bodies, and frames
• Loading ramps and docks
• Railings, stairs, and aluminum plates
• Door and window frames
• Irrigation piping
• Transmission housings and gearboxes
• Engine and motor blocks
• Machine bases and supports
• Bus bars and electrical components
