Tungsten welding rod sizes.

There are various tungsten electrodes that you can use for the process but not all will prove efficient. Tig stands for tungsten inert welding and in a more technical sense it s known as gas tungsten arc welding gtaw. This size 3 32 or 2 4 mm is not overly large but it has a positive strength point and is compatible with the majority of welding amperage needs and ranges. One more thing to consider is that you may find yourself doing a lot of grinding of the electrode to sharpen it and prepare it.

A bad low quality earth or a low voltage supply can seriously lower the maximum welding capabilities of your welder. Zirconiated tungsten electrodes aws classification ewzr 1 contain a minimum of 99 10 percent tungsten and 0 15 to 0 40 percent zirconium. Smaller tungsten sizes tend to snap more easily. The tungsten electrode is a critical component in the process as it channels the current required to establish the arc.

The tungsten electrodes can be alloyed with a variety of metals. The success of tig welding depends on a number of factors. Gas tungsten arc welding gtaw also referred to as tig uses a non consumable tungsten electrode to create an arc between the electrode and the parent material. Different types and sizes of electrodes are used for different types of welds and materials and welders develop preferences based on welding style and project.

A zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. It is ideal for ac welding because it retains a balled tip and has a high resistance to contamination.
