Make Use Of An Argon Mix To Mig Weld Aluminum

Metal Inert Gauze (MIG) welding is an arc welding channels that utilizes a fixed voltage, conduct ongoing gift source to food a continual, consumable wire electrode and an inert shielding Gauze terminated the welding gun. This mechanism was developed for welding aluminium and other non-ferrous materials and is one of the easiest, quickest and most adaptable industrial welding processes. Argon and helium are the inert shielding gases used in MIG welding aluminium.


Using Argon or an Argon Mix


Adoption either argon or a merge of 40% argon and 60% helium as the inert shielding gases, when MIG welding solitary aluminium, by reason of MIG welding other thin metals using by oneself argon as the inert shielding Gauze can ruin the weld and damage the metal. Practice a flow degree between 40 and 60 cubic feet per interval on an argon flow metre when MIG welding with matchless argon. Custom a flow proportion between 50 and 100 cubic feet per day on a helium flow metre for an inert shielding Gauze merge of argon and helium. Applicability lone a "push manner" when MIG welding aluminum since the soft metal is easy to burn and perforate. This technique involves pushing the welding gun ahead of the weld puddle To admit for a flatter weld bead and wider inert shielding gas coverage since the force from the arc is directed away from the weld puddle itself.


Tips & Precautions


Whether using a spool gun or short welding gun, pause in the weld pool for a moment at the end of the weld to avoid a crack in the wire electrode and to fill the crater. Never do any MIG welding outdoors since the air volatility may not only result in a poor weld and a damaged welding gun, but can also be dangerous.Use a stainless steel wire brush specified for cleaning only aluminum to remove the oxide layer from the metal before MIG welding. Use a spool gun for best results when MIG welding aluminum. If you do not have access to a spool gun, then use a short welding gun and keep the gun as straight as you can so the wire electrode feeds correctly.
