As a result, they will take up too much of a welders costly time to produce an electrode that may not weld to the highest quality or weld for very long. Our guide, Zoltan, sparks up his morning smoke, a cheap brand of Russian cigarettes, as his partner Lazslo gazes off into the darkness. This tungsten is primarily used for DC welding, but will also show good results for AC welding. Excellent non-radioactive substitute for 2% Thoriated tungsten. For applications like orbital welding, which require extreme tolerances, DGP offers pre-ground Welding Electrodes that are cut, ground, and finished to the users specifications. Sole with non-slip wear-resistant nail bottom design, running freely. The DGP factory is a One-Stop-Shop for all of your tungsten needs. In any case, it is much easier to cut an electrode quickly and properly with the correct cutting apparatus designed specifically for how hard and brittle tungsten is. To produce the high quality orbital fusion welds required of today's high tech industries, tungsten electrode shape is an important variable that must be kept consistent. Diamond Ground Products is dedicated to the improvement of weld quality & welder productivity, and maintains a reputation as the industry leader in tungsten and tungsten preparation. Uneven distribution results in poor performance: areas with little or no oxides will tend to suffer from grain growth, whereas areas with too much oxide will tend to bottleneck and prevent the oxides from getting to the point. It is also especially good at (a) resisting the Thermal shock of pulsing, (b) working in welding in situations where there are numerous re-ignitions with a short weld cycle, and (c) resisting contamination. Refer to Table 1 of AWS A5.12M/A5.12:2009 Specification for Tungsten and Oxide Dispersed Tungsten Electrodes for Arc Welding and Cutting. Diamond Ground Products recently exhibited a range of welding accessories, including some of our wide range of Tungsten Grinders, at the Schweissen & Schneiden Welding Exhibition in Essen, Germany. What is the Correct Tungsten Electrode for Welding? 805-498-9347 www.diamondground.com sales@diamondground.com "The Tungsten Electrode Experts" DIAMOND GROUND PRODUCTS Pre-Ground Tungsten Electrodes For: ORBITALS MECH. Zirconiated tungsten electrodes (EWZr) contain a small amount of zirconium oxide (ZrO2). A high-polished or mirror-like finish of approximately 6-8 RMS, where few or no lines can be seen, is better for the longevity of the electrode because without any grit to the electrode surface, it is much less likely for contamination to stick to the electrode point and thus less erosion takes place. Toggle navigation. For the latter, the end is typically ground to a specific included angle, often with a truncated end. International Color Coding Chart:Each stick of tungsten has a color code applied to one end which identifies the material type of the tungsten. We are "The Tungsten Electrode Experts.". Diamond Ground Products Ltd is dedicated to the improvement of weld quality & welder productivity, and maintains a reputation as the industry leader in tungsten and tungsten preparation. V-Groove with Top Bearing Bits. If this does happen, the contaminated portion of the tip should be cut off; the electrode should be reground from the beginning. Always follow standard safety guide lines when operating high speed grinding equipment. Lower temperatures improve the longevity of the tungsten and keep the grains within the tungsten smaller for improved arc stability. In addition, the surface finish of the grind is also important. More pointed tips in the 10 to 25 included angle range are used for lower current. These electrodes contain 2 percent lanthanum oxide (La203). Diamond Ground Products Ltd is dedicated to the improvement of weld quality & welder productivity, and maintains a reputation as the industry leader in tungsten and tungsten preparation. The best way to determine which tungsten material is best suited for a particular application is through testing. A standard finish of around 20 RMS, which would still show the longitudinally ground lines to the naked eye, is an all-purpose, quality finish for any application. Also, if the tungsten shatters there is the risk of eye or hand injury. Work function is the energy needed to remove an electron from an atom, and it is measured in electron volts (eV). The tungsten electrode becomes overheated and wears out more quickly.
