The 2 percent thoriated (color code red) tungsten electrode is an all-purpose tungsten electrode that is recommended for welding mild steel because it performs well at lower temperatures, which is exactly what you need if you don’t want the steel to warp during the welding process. So, here are my top selections for this year!
– The size of the electrode The most often used tungsten electrode diameters vary from 3/32 to 1-1/4 inch in diameter.- Geometry of the electrodes –.In order to establish a concentrated arc capable of creating deep, thin beads and a small heat-affected zone, the electrode diameter should be no more than 2.5 times the electrode diameter.- Control with the fingertip and the foot.- The size of a puddle – The rate at which the gas flows and the distance traveled.
What type of tungsten is used for steel?
Ceremonies were held (Color Code: Orange) It is similar to thorium in that it is best suited for welding carbon steel, stainless steel, nickel alloys, and titanium, and it can in certain situations be used to substitute 2 percent thoriated electrodes in specific applications.Even though ceriated tungsten has somewhat different electrical properties than thorium, the majority of welders are unable to distinguish the difference.
What color tungsten is for what?
Tungsten electrodes are identified by their color designations.
|Identification code||Weight of oxide in %||Colour|
|WT 10||0.80 – 1.20||Yellow|
|WT 20||1.70 – 2.20||Red|
|WT 30||2.80 – 3.20||Purple|
|WT 40||3.80 – 4.20||Orange|
What color tungsten is used for welding steel?
Red tungsten is suited for specialist arc welding applications, including but not limited to welding materials with a thickness of less than 0.0and welding aluminum with a gauge of less than 0. Red tungsten is also favored for direct current welding (DC welding) on nickel, steel, stainless steel, and titanium utilizing straight polarity or electrode negative.
What color tungsten is for stainless steel?
When it comes to stainless steel, what color tungsten do you use? The red TIG tungsten electrode is the most often used electrode because the 2 percent thorium combined with the tungsten makes it both robust and diverse in its use. Because of the thorium, arc starts are easier to initiate and current carrying capacity is increased.
What is GREY tungsten used for?
They are excellent for welding titanium, copper, magnesium, aluminum, and nickel alloys as well as non-corroding and stainless steels, and they operate well in direct current (DC) applications.
What is the purple tungsten?
Electrodes made of rare earth elements (purple). The novel Rare Earth Blend tungsten electrode is composed of 98.34 percent tungsten, 1.5 percent lanthanum, 0.08 percent Zirconium, and 0.08 percent Yttrium, with the remaining 0.34 percent lanthanum. It is an excellent alternative for red thoriated electrodes in many applications.
What color material is tungsten?
Green (EWP) = Tungsten in its purest form. Ceriated is represented by the color orange (EWCe-2). Red (EWTh-2) indicates that the animal is 2 percent thoraxed. Gold (EWLa-1.5) is composed of 1.5 percent Lanthanated ethyl acetate. Specific Tungsten Colors and Where and How to Use Them
|Electrode Diameter||DC Amps||AC Amps|
What is orange tungsten?
4 percent of the total amount of THORIATED (ORANGE). In the United States, thoriated tungsten is the most often utilized kind of tungsten. This tungsten is typically utilized in direct current welding. It has a modest work function but has a high load and amperage capabilities due to its design.
What is red TIG tungsten used for?
Thoriated to a degree of 2 percent in red. Mild steel and stainless steel are both suitable for Tig welding.
What color is a Ewp tungsten?
Electrodes for welding made of pure tungsten (99.5% tungsten minimum) that are non-radioactive are available from Blue Demon Pure Welding Tungstens (EWP). These Pure Tungsten electrodes are color coded Green to make them easier to distinguish from one another. The current-carrying capacity of pure tungsten electrodes is lower than the current-carrying capacity of other tungsten electrodes.
What is pink tungsten?
It is a proprietary product that contains a number of additives made from rare earth metal oxides. Each additive works in conjunction with the others to improve the welding performance. Because it does not emit radiation, it is a preferred alternative to thoriated tungsten. With multi-Mix tungsten electrodes, you may utilize them at any current range on both DC and alternating current TIG.
What is white tungsten used for?
White zirconiated tungsten electrodes are capable of handling greater amperage levels and working with both transformer and inverter power sources, making them an ideal alternative to the environmentally friendly pure tungsten electrodes used in magnesium and aluminum alloys production.
What is tungsten and should I buy it?
As a good alternative to environmentally friendly pure tungsten electrodes for magnesium and aluminum alloys, white zirconiated tungsten electrodes can tolerate higher current levels and operate well with both transformer and inverter power sources.
