GMAW (MIG) Aluminum Welding Hints

Here are several hints to help you be more successful with your new aluminum feed system.

MIG welding aluminum requires different techniques than MIG welding mild steel.

A. Before You Start Welding

� The removal of lubricants from the aluminum base material may be necessary. Consult with your local welding distributor for their recom-

mendation on aluminum cleaners.

� Oxide removal should be done after degreasing. This should be done with a stainless steel wire brush. This can be done with a hand wire

brush or with a cup wire brush. If a power wire brush is used, keep the RPM's and pressures low to reduce smearing the surface of the mate-

rial, which could entrap oxides and impurities under the surface. Always use a wire brush that is used only on aluminum to keep from con-

taminating the base material.

� Contact you local welding distributor or aluminum filler metal representative for recommendations on wire alloys that fit your application.

Know the alloy of your base aluminum and what conditions the finished part will be subjected to. The two most readily available aluminum

filler wires are ER4043 and ER5356.
