How To Weld Aluminum Tungsten

Remember that AC welding requires largerdiameter tungsten electrodes. A TIG welder basically comes with both AC and DC power options.

Tungsten Inert Gas TIG aluminum welding refers to the use of a non-consumable tungsten electrode to deliver current to the welding arc.

How to weld aluminum tungsten. How To Ball Your Tungsten For Welding Aluminum - YouTube. Almost all direct current electrode negative DCEN welding that has been done in the past was with 2 percent thoriated electrodes although more recently lanthanated and ceriated electrodes have become more popular for this type of welding. Cut tungsten electrodes 040062 diameter with wire cutters or used their hands.

Pure tungsten DC only. The most important thing when TIG welding aluminum to set up is the Tungsten electrode. Keep the welder running for 2 3 minutes till a ball of 13 the diameter of the tungsten electrode is observed on the tip of the electrode.

If playback doesnt begin. How is Tungsten Balled for Aluminum Welding. The welder holds the electrode over the workpiece and melts it by striking up the arc while continuously feeding a filler rod or consumable to the weld pool.

Clean your aluminum remove any oxide and file the edges that will be joined Avoid pulling while weldinginstead push at a 10 to 15 degree angle Use multiple pass straight beads to improve the overall appearance of the weld and help to avoid defects Use a heat sink which will absorb extra heat and allow you to weld slower. Some welders like the way aluminum welds with a nicely rounded tip. Other key features include reduced arc wandering and improved stability while depositing less tungsten into the weld puddle.

How To Ball Your Tungsten For Welding Aluminum. Make sure you use a tungsten electrode large enough in diameter to carry the welding current you plan to use. Dont use a 2 percent thoriated tungsten electrode.

Hold the tip of the tungsten about ¼ inch 64 mm away from the aluminum. What most people find challenging about this type of welding is that you must use both hands while welding. You need to find out the best tungsten for stainless steel such as aluminum.

Use just enough amperage by pressing on the foot pedal to barely melt and round the tipyou can easily see it get really hot quick on reverse polarity. Use a pure tungsten or zirconiated tungsten electrode when AC welding aluminum. Besides this you have to know how to apply it over the aluminum.

Since youre going to weld aluminum using TIG welding youll need to choose either the DC positive or DC negative power. Second it makes it easier for the tungsten to emit electrons which gives it a higher current-carrying capacity compared to pure tungsten. Learn About Tungsten for TIG Welding Aluminum.

While placing the base of your gloved hand on the table for support hold the torch at a slight angle tilting back about 10. Red tungsten is also preferred for DC welding using straight polarity or electrode negative on nickel steel stainless steel and titanium. Dont make a ball like a tootsie roll just use enough amperage to round the tip.

Sharpen one side of the pure- tungsten electrode to a spiky tip using a bench grinder. To weld it you either need pure Tungsten or Zirconium Tungsten. Cut tungsten electrodes over 18 diameter using a sharp hammer blow to the electrode on.

Now start up the welder. 2 ceriated on AC 2 lanthanated AC and DC 15 lanthanated AC and DC 2 thoriated DC only Green. The 2 lanthanated Tungsten is probably the best choice as it can hold up at higher amperages.

You should select the perfect color size and shape. Tungsten is a magical thing for TIG welding sectors. The Tungsten should also have a ball-shaped head in order to properly spread heat.

As a welder you should know the application of tungsten in arc welding. Put the sharpened electrode aside for 10 minutes letting it cool down. The following electrodes can be used for TIG welding aluminum but there are a few rules and caveats that will need to be discussed below.

Red tungsten is ideal for specialty AC welding including but not limited to welding materials less than 00andand for thin-gauge aluminum. Cut tungsten electrodes 332 to 18 diameter by using 2 pairs of pliers and a twisting motion or notched the electrode on the grinding wheel and used two pairs of pliers. Place the sharp tip of the electrode 18 inch away from the scrap piece of aluminum.

Again let the electrode rest.
