Frequently Asked Questions
What is Harris 4043 aluminum MIG welding wire?
Harris 4043 is an ER4043 aluminum-silicon filler metal designed for MIG / GMAW welding. It is commonly used with heat-treatable aluminum alloys, especially 6XXX-series base materials.
What welding process is used with Harris 4043 wire?
This product is designed for gas metal arc welding (GMAW), commonly referred to as MIG welding.
What aluminum alloys are commonly welded with ER4043?
ER4043 is commonly used with heat-treatable aluminum alloys, particularly 6XXX-series materials, along with many compatible aluminum casting alloys.
Why is 4043 commonly used for aluminum welding?
4043 aluminum filler metal provides good fluidity, a relatively low melting point, and low sensitivity to weld cracking when used with compatible base materials.
Can Harris 4043 be used for aluminum casting repair?
Yes. Harris identifies 4043 as commonly used for repair welding aluminum/silicon cast alloys, including casting grades such as A356.
What shielding gas should be used with Harris 4043 MIG wire?
Harris identifies 100% Argon or Argon / Helium mixtures as suitable shielding gases, with a recommended flow rate of approximately 30–50 CFH.
Can Harris 4043 be welded in all positions?
Harris identifies the filler metal for all welding positions except vertical down.
Should ER4043 be used on 5XXX-series aluminum?
Harris advises against welding 5XXX-series base materials with 4043 and other 4XXX-series filler metals. Always confirm filler-metal compatibility with the base alloy and applicable welding procedure before use.
