How to Weld Aluminum

Welding refers to the process of joining two metals together and professional handyman Los Angeles are capable of doing this job. Welding is truly a challenging process, especially if you’re not trained for the job. You may be able to handle lightweight metals such as aluminum, but welding requires utmost precision in order to ensure a strong and lasting bond.

If you want to know how to go about this, below are a few steps to help you out:

Set the Amperage of Your Welder

The first step is to set the proper amperage of your machine. Try to use at least one amp per 0.001 inch of the metal’s thickness. It is recommended that you set the amperage of the machine higher than what you thought you need and then tone the current back using a foot pedal.

Gather Your Tools and Setup Your Workpiece

Start by extending the tungsten electrode into a size no more than the diameter of the nozzle of the torch. For instance, if you’re using a nozzle that’s 1/4 inch in width, the tip of your tungsten must not extend more than 1/4 inch from the nozzle. Next, tap the tip of the electrode against the metal you are working on and then pull about 1/8 inch away.

Press the Button on the Torch

If the torch of your machine comes with a button that you can press at the torch, then go ahead and do so. This is how you will produce your first electrical arc. Pressing the button will activate the high-frequency feature since it is linked to a cable that’s connected to the power supply. This is the easiest way to create an electrical arc.

Use the Foot Pedal

If you are not seeing a button at the torch of the handyman services Los Angeles machine, then you need to produce the arc through a foot pedal. Gently press the pedal at least halfway down to create the arc. If you’re having problems with starting the arc, then this means that your amperage is just too low. Adjust the setting of the amperage and then try it once again.

Create the Puddle

When creating a puddle, melt the aluminum piece until you are able to produce an adequately sized puddle. Add just enough filler rod in order to fill the joint and move on to the next part of the weld. Continue the process until the entire joint has been properly welded.

When you go on with the welding process, you will notice that the heat will increase all throughout the piece of aluminum that you are working on. Step on the foot pedal in order to lower the amperage and try to gain control over the puddle.

While you operate the Los Angeles handyman machine, pay attention to the size of the metal puddle. If it is too small or too big, you could burn the material and you might not produce a solid weld.
