What is 2% Lanthanated tungsten used for?

What is 2% Lanthanated tungsten used for?

2% Lanthanated (Blue) Blue electrodes are effective for welding aluminum alloys, magnesium alloys, nickel alloys, copper alloys, titanium alloys, low-alloyed steels, and non-corroding steels.

What is Lanthanated tungsten?

You can use blue lanthanated tungsten as an all-purpose option with a variety of metals, including nickel alloys, aluminum, cobalt, copper, carbon steels, and titanium.

What is the best tungsten to use on mild steel?

2% Thoriated Tungsten Electrode. The 2% thoriated (color code red) is an all-purpose tungsten electrode and it’s recommended for welding mild steel because they work well on lower temperatures, which is what you need if you don’t want the steel to warp.

Why is tungsten used in welding?

Tungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion. Electrodes are made by powder metallurgy and are formed to size after sintering.

What is Lanthanated tungsten good for?

Lanthanated tungsten electrodes are ideal if you want to optimize your welding capabilities. They work well on AC or DC electrode negative with a pointed end, or they can be balled for use with AC sine wave power sources.

Are Lanthanated electrodes radioactive?

Non-radioactive 1½% lanthanated tungsten is an alternative to this material that provides for an easy transition and often produces better performance.

What is purple tungsten used for?

Rare Earth (Purple) Electrodes It is the perfect substitute for red thoriated electrodes. They perform well in DC applications and are great for welding copper alloys, nickel alloys, titanium alloys, and stainless steel.

What can 2% lanthanated tungsten be used for?

2% lanthanated tungstens can also be used in the AC frequency to weld aluminum while providing a very nice arc and a low burn-off rate of the electrode. They are a mix of the best qualities between ceriated electrodes and thoriated tungsten for DC and zirconiated for AC.

What’s the difference between lanthanated and zirconated tungsten?

Zirconated tungsten typically is 99% tungsten and only have a very small percentage (usually less than 1%) of zirconium in them. They are color-coded brown or white and really don’t measure up to lanthanated tungsten at all. Zirconated tungsten may be more comparable to gold (1.5%) lanthanated tungsten.

Can you use thoriated tungsten in AC welding?

For example, thoriated tungsten cannot be used in AC welding but lanthanated tungsten can be used for AC and DC, with few limitations, if any. Lanthanated tungsten allows you to start and maintain your arc at lower voltage levels. At the same time, you can upsurge the current by up to 50% for any electrode size that you might use.

What’s the ratio of lanthanum to tungsten in gold?

Gold is a combination of tungsten and lanthanum with the lanthanum being anywhere between 1.3 and 1.7%. It’s typically referred to as 1.5% lanthanated for this reason. The arc is stable and easy to initiate.
