Tungsten Welding Rod Sizes

Below are five tables that will help select the correct current and tungsten size type when initially setting up your tig welder tweak and change as necessary for your own situation.

Tungsten welding rod sizes.

The process utilizes a non consumable tungsten electrode that relays current to the welding arc. The success of tig welding depends on a number of factors. 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 bad low quality earth or a low voltage supply can seriously lower the maximum welding capabilities of your welder.

Smaller tungsten sizes tend to snap more easily. Zirconiated tungsten electrodes aws classification ewzr 1 contain a minimum of 99 10 percent tungsten and 0 15 to 0 40 percent zirconium. 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. 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.

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. It is ideal for ac welding because it retains a balled tip and has a high resistance to contamination. A zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. The tungsten electrode is a critical component in the process as it channels the current required to establish the arc.
