A pointed and/or truncated tip (for pure tungsten, ceriated, lanthanated and thoriated types) should be used for inverter AC and DC welding processes. ... When welding with lower currents on thinner materials (those ranging from . 005- to . 040-in.), it is best to grind the tungsten to a point.

Then, what is the best tungsten for mild steel?

2% Thoriated Tungsten Electrodes – Red Tipped Containing 1.7% to 2.2% thorium oxide, this radioactive tungsten electrode works well with mild steel, stainless steel and other non-corroding metals. Red-tipped tungsten electrodes fall in the mid-range for amperage and erosion, as well as spitting tendencies.

Afterall, what color tungsten do you use to weld aluminum? Green

Despite everything, is Ceriated tungsten radioactive?

Non-Radioactive Tungsten Materials The first one, introduced in the 1980's, is most commonly available as 2% ceriated tungsten. This material is commonly used for lower amperage DC welding applications.

What is the most common use of tungsten?

Current uses are as electrodes, heating elements and field emitters, and as filaments in light bulbs and cathode ray tubes. Tungsten is commonly used in heavy metal alloys such as high speed steel, from which cutting tools are manufactured. It is also used in the so-called 'superalloys' to form wear-resistant coatings.

What is purple tungsten used for?

This rare earth tungsten offers excellent ignition characteristics and consistent welding properties. They are universal and suitable for all applications in the whole range of AC and DC welding of non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys.

How dangerous is thoriated tungsten?

During the grinding of the thoriated tungsten electrodes, radioactive dust is created, posing the potential hazard of internal radiation exposure by inhalation or ingestion unless care is taken to control the dust. electrodes such as those containing cerium, lanthanum, yttrium, or zirconium whenever possible.

What is blue tungsten used for?

How many amps do you need to weld aluminum?

Use Appropriate Amperage The rule of thumb for aluminum GTAW is to use 1 amp for every thousandth (0.001) of material thickness. In other words, welding a base material that is 1⁄8 in. (0.125) thick would require about 125 amps.

What type of welder do you use for aluminum?

For aluminum, a TIGtungsten inert gaswelding machine is a better choice than a MIG machine. While MIG machines can be used, TIG machines are preferred by most professionals taking on complex aluminum welding tasks.

Why does my Tungsten melt?

TIG electrodes melt due to a variety of reasons, the most common are: diameter of the electrode too small for set current, the polarity of the torch is clamped electrode positive, welding with DC instead of AC or the electrode material is not suitable for the welding setup.

Is Tungsten toxic?

All tungsten compounds should be regarded as highly toxic. The metal dust presents a fire and explosion hazard.
