Tungsten welding rod sizes.

The tungsten electrode is a critical component in the process as it channels the current required to establish the arc. 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. 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 process utilizes a non consumable tungsten electrode that relays current to the welding arc. This arc creates a molten pool to which a filler wire is added. A bad low quality earth or a low voltage supply can seriously lower the maximum welding capabilities of your welder. There are various tungsten electrodes that you can use for the process but not all will prove efficient.

The success of tig welding depends on a number of factors. 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. 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. 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.

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.
