Tungsten Welding Rod Sizes

This arc creates a molten pool to which a filler wire is added.

Tig stands for tungsten inert welding and in a more technical sense it s known as gas tungsten arc welding gtaw. The success of tig welding depends on a number of factors. A zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. The process utilizes a non consumable tungsten electrode that relays current to the welding arc.

It is ideal for ac welding because it retains a balled tip and has a high resistance to contamination. 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. A bad low quality earth or a low voltage supply can seriously lower the maximum welding capabilities of your welder. 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.

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. 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. 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. 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.
