Tungsten Welding Rod Sizes

There are various tungsten electrodes that you can use for the process but not all will prove efficient.

Tungsten welding rod sizes.

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. A zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. 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. 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. The process utilizes a non consumable tungsten electrode that relays current to the welding arc. Tig welding parametres table.

Smaller tungsten sizes tend to snap more easily. 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. Zirconiated tungsten electrodes aws classification ewzr 1 contain a minimum of 99 10 percent tungsten and 0 15 to 0 40 percent zirconium. A bad low quality earth or a low voltage supply can seriously lower the maximum welding capabilities of your welder.

This arc creates a molten pool to which a filler wire is added. The tungsten electrode is a critical component in the process as it channels the current required to establish the arc.
