Welding Aluminium With A Spool Gun

Why is a spool gun recommended for aluminum welding. The wire speed control determines how much wire per minute will feed through your gun while the voltage controls the amount of heat and penetration.

Pin On Welding

When welding aluminum you are dealing with a much softer metal.

Welding aluminium with a spool gun. Ad Find China Manufacturers Of Aluminum Welding. The spool gun should always be pushed and ideally held at about a 20-degree work angle to ensure the shielding gas can keep the atmosphere away from the weld zone. There are two controllable parameters on this process we will be setting it up for welding 8mm aluminium.

Since aluminum is a very soft material it will get scratched or scraped off if it is made to travel a. There is a lot of push in the welding community to use a spool gun for welding aluminum. This system consists of a small spool of wire that is located on the welding gun.

These two parameters need to work in harmony to get a sufficient weld. Aluminum welding utilizes the much faster spray transfer mode which may take some getting used to since the spool gun needs to be moved quickly to keep up with the process. But what are those challenges and how does a spool gun help.

But why is that. This is because they make it much easier to handle the soft wire that is used to weld aluminum. Bulky spool guns are difficult to use in tight spaces.

Mig Welding Aluminum with a Spool Gun - YouTube. In this video you can see that when mig welding aluminum the weld puddle is pushed and not pulled. 1wire feed speed.

Watch this video to learn how to MIG weld aluminum with a spool gun. Push-pull type wire feeders such as this one are commonly used for MIG welding aluminum. With its short feed distance a spool gun provides a steady reliable feed of the soft aluminum wire.

Aluminum welding with a spool gun is very sensitive to wire feed speed. For Mig Welding aluminumYou most often need a spool gun. A smooth feed to the weld is key to getting that smooth arc.

Because of this youll. Successful welding with aluminum requires a stable arc. A smooth humming or hissing spray transfer is the goal with little or no sputtering sound.

The simple answer is the ease of use. A spool gun reduces the distance through which the aluminum has to travel to reach the weld puddle. The main culprit is wire feeding issues.

You can also notice the cleaning action of the arc around the edges of the weld puddle that breaks up the aluminum oxide and allows the puddle to wet in to the base metal. This system consists of a pull motor in the welding gun and a push motor in the feeder together they add extra tension to the wire. Slightly too much wire feed speed and the arc is not smooth.

Spool guns that are designed for aluminum wire eliminate some of the challenges aluminum welders face. Ad Find China Manufacturers Of Aluminum Welding. Restore Vision Fast and Naturally From Home.
