Tungsten Welding Rod Colors

The electrode choices are pure tungsten 2 percent thoriated 2 percent ceriated 1 5 percent lanthanated zirconiated and rare earth.

Tungsten welding rod colors.

Suitable for dc and ac welding. 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. Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding gtaw. The tungsten electrode is a critical component in the process as it channels the current required to establish the arc.

Can be used for unalloyed and high alloy steels. In addition tip preparation is critical. Tig stands for tungsten inert welding and in a more technical sense it s known as gas tungsten arc welding gtaw. Arc length bead length temperature of base material how clean and smooth the surface is tungsten angle your motion while welding the direction you re welding if there s a back purge or backing plate and post flow all affect the final color or lack thereof.

The end preparations are balled pointed and truncated. Aluminium titanium nickel copper and magnesium alloys. The process utilizes a non consumable tungsten electrode that relays current to the welding arc. Tungsten electrodes for ac welding of aluminium alloys.

The tungsten electrodes can be alloyed with a variety of metals. Increased ignitability thanks to lanthanum oxide. Only limited suitability for dc welding. There are various tungsten electrodes that you can use for the process but not all will.
