Tungsten For Aluminum Welding

Remember that ac welding requires larger diameter tungsten electrodes.

Tungsten for aluminum welding.

Pure tungsten green stripe for years was the best choice for ac welding but with the industry shift to invert based machines with advanced squarewave technology rare earth tungsten such as ceriated gray stripe and zirconiated brown stripe are an option. What most people find challenging about this type of welding is that you must use both hands while welding. It is mostly used for melting metals. Don t use a 2 percent thoriated tungsten electrode.

Generally aluminum alloys are welded using alternating current ac. Use a pure tungsten or zirconiated tungsten electrode when ac welding aluminum. If you are looking for an electrode to weld aluminum then you are most probably looking for the best tungsten for aluminum. They are selected for their longevity and ease of use.

If you intend to sharpen this electrode please remember that thorium is radioactive and take care. Make sure you use a tungsten electrode large enough in diameter to carry the welding current you plan to use. But there are so many types of electrodes in the market. To weld thin sheets and small and delicate parts you may need to use gas tungsten arc welding gtaw electrodes.

With that in mind what is the best tungsten electrode for tig welding aluminum. So here are a few tips and general rules that will help you start. Tungsten inert gas tig aluminum welding refers to the use of a non consumable tungsten electrode to deliver current to the welding arc. The tungsten you choose will depend on a few factors.

Thoriated tungsten is a common choice of electrode for a variety of welding work. These electrodes are used in ac welding which is ideal for thin sheet aluminum. However when people started to aluminum gtaw using alternating current ac they found out thoriated electrodes really weren t well suited for that type of welding. Welding aluminum is the hardest task for welders.

The 2 lanthanated indicates that they are suitable for welding aluminum. In ac gtaw much more energy is taken up by the tungsten than is taken up in dcen welding. The jeweler is very attached to this stone for designing jewelry. They include your particular machine the thickness of the metal you re welding and the settings you have available.
