Description

Experience the superiority of Weldcote Aluminum 4043 TIG welding rods. With over 60 years of experience manufacturing high-quality filler metals, Weldcote delivers exceptional performance you can trust. This 4043 aluminum welding rod is commonly used for welding 3003, 5052, 6061, and other common alloys.

Premium Quality Filler Metal for Aluminum Fabrication

This 3/32″ x 36″ 4043 aluminum rod contains 5% silicon and offers tremendous feedability in mechanized applications. The smooth arc starts easily without rod sticking. You’ll appreciate the smooth, crisp arc with no splatter and excellent puddle control. The silicon deoxidizes the weld puddle for improved fluidity. This results in quality welds with good penetration and wetting action.

The 4043 aluminum MIG wire feed welds have appearance and strength similar to the base metal. It’s also easy to remove slag after welding. Whether you’re welding aluminum for aerospace, automotive, structural applications, or hobby projects, this filler metal delivers top-tier performance.

Key Features and Benefits

  • 10 lbs of 3/32″ 4043 aluminum TIG welding rod
  • Contains 5% silicon for deoxidizing the puddle
  • High silicon promotes fluid weld puddle
  • Easy arc starts without rod sticking
  • Great puddle control and wetting action
  • Minimizes porosity in the weld
  • High quality ER4043 filler metal
  • Used for TIG and MIG welding aluminum
  • Matching strength and appearance to base metal
  • Trusted Weldcote quality for over 60 years

This 4043 welding rod consists of the following composition:

  • Silicon: 4.5-6%
  • Magnesium: 0.05% max
  • Iron: 0.8% max
  • Copper: 0.3% max
  • Manganese: 0.05% max
  • Remainder Aluminum

The higher silicon content allows the weld puddle to remain fluid for a longer time before solidifying. This gives you more control over the puddle and results in smooth, attractive welds free of defects. The 4043 filler rod offers low melting temperature, great fluidity, and quality wetting action.

Applications

The 4043 aluminum welding rod excels in these applications:

  • Welding 6061, 3003, 5052, and other common aluminum alloys
  • MIG welding aluminum
  • TIG welding aluminum
  • Automotive parts and components
  • Aluminum trailers, railings, frames
  • Heat exchangers, ducting
  • Electrical boxes, electronic chassis
  • Aerospace, aircraft structural components
  • Architectural aluminum fabrication

Whether you’re a professional welder or a hobbyist tackling your first aluminum project, this Weldcote 4043 filler metal provides quality and consistency you can rely on. The smooth arc and great puddle control make aluminum welding projects easier.
