Application
E4043 CTD is a coated electrode designed for maintenance welding of aluminums and aluminum alloys, such as 5454, 5154, 6052, 606 and 700 series.

  • The proper choice of aluminum filler metal mainly depends on the base metal properties to be achieved andwelding technique. Post weld cracking, corrosion resistance and behavior under elevated temperature also needto be taken into consideration.
  • Cracking usually can be minimized by choosing a filler metal alloy of higher alloy content then the base metal.
Deposited Chemical Composition % (Typical)
Si = 5.00 Cu = 0.20
Ti = 0.11 Al = Balance

Recommended Operation of Welding Rods
Weld parameters are dependent on diameter, of weld material and position of welding including base plate thickness.
