The Classification of Welding Electrodes "What do all the numbers refer to that are printed on electrodes?" The Layman might be puzzled by the array of letters and numbers that are printed on the end of welding electrodes. They are there to classify the type of electrode. Most of the welding rods will use the AWS system which stands for
Zirconiated Tungsten (EWZr-1 Electrode Classification: Brown Stripe; and EWZr-8 Classification: White Stripe) Zirconiated tungsten electrodes (EWZr) contain a small amount of zirconium oxide (ZrO2). Zirconiated tungsten electrodes have welding characteristics that generally fall between those of pure and Thoriated tungsten.

Aug 21, 2017· In GTAW (Gas Tungsten Arc Welding) also known as TIG welding (Tungsten Inert Gas welding), a non consumable electrode (made up of Tungsten) is used. Tungsten is preferred due to high its high melting point (approximately 3,410 0 C) and high hardness. Either pure tungsten is used as electrode or it can be alloyed with other elements.

The American Welding Society’s classification number series for welding electrodes has been adopted by the welding industry. The electrode identification system for steel arc welding is set up as follows:
Some electrodes can be used with only AC or DC power sources while other electrodes are compatible with both. To determine the correct current type for an electrode, refer to the second two digits of the AS/NZS classification (see figure 1), which represents the type of coating and type of compatible welding current (see figure 2). Figure 1 ...
May 20, 2018· Classification of Welding Electrodes. This classification is based on practical approach towards using and selecting welding electrodes. The American Welding Society has classified electrodes in different formats for proper understanding of different electrodes easily and to identify them comfortably.

Jan 31, 2019· Welding is the process of fusing two pieces of metals (also called workpiece) together. This is accomplished by passing electric current from the welding electrode to the workpiece that creates an electric arc. The electric arc heats and melts the two metals together, which in turn, fuses the two metals together resulting in a stronger bond.
and are AWS classifications for Shielded Metal Arc Welding (SMAW) stick electrodes. These two types are very similar but the main difference between the two is with the recommended welding polarity. Welding Training – Welding Basics For Beginners No strings attached assisted welding metal art projects Key to electrode classification numbers.
The Different Types of Electrodes: What Do Welding Rod Numbers Mean? As you’ve probably noticed, different types of welding rods and electrodes come with letters and numbers. These can seem like a foreign language if you’ve never learned about AWS welding electrode classification. But don’t worry – we’ve got you covered.
The two MMA electrode classification schemes that will be dealt with in this month's article are the EN (Euronorm) and the AWS (American Welding Society) specifications. There is insufficient space to cover in detail the whole range of compositions for MMA electrodes so the emphasis here will be on the carbon steel filler metals.
Jul 12, 2017· Electrode color is mostly cosmetic and often results from oxides that become part of the slag system. Don’t select an electrode by its color; confirm the AWS classification and/or electrode name by looking at the printing on the coating. For the curious, colors …

The American Welding Society (AWS) numbering system can tell a welder quite a bit about a specific stick electrode including what application it works best in and how it should be used to maximize performance. With that in mind, let's take a look at the system and how it works. The prefix "E" designates an arc welding electrode.
A5.1 (Carbon Steel Electrodes for Shielded Metal Arc Welding) This AWS specification provides the standards for, among other filler metals, a common classification of stick electrode: E7018. Like other stick electrodes, E7018 products have four key designators in their classification. See Figure 1.
**Arc Welding Electrode Classification System. ** The SMAW electrode classification code contains an E and three numbers, followed by a dash and either “15” or “16” (EXXX15). The E designates that the material is an electrode and the three digits indicate composition.
Grainger offers a collection of stick electrodes, excellent for use with filler metals and welding arcs. A staple for welding and metalworking, the stick electrode serves a great importance for all joint welding procedures. Our electrode sticks allow you to engage in carbon steel and aluminum projects.
WELDING ELECTRODE CLASSIFICATION SMAW MILD STEEL COATED ELECTRODES E7018-X E Indicates that this is an Electrode. 70 Indicates tensile strength. Measured in thousands of pounds per square inch. 1 Indicates welding position. 8 Indicates the coating, penetration, and current type used. (See Classification Table below)
As with any part of the welding operation, greater knowledge can lead to greater welding performance. Regardless of the filler metal being used for the job – stick electrode, solid wire or flux-cored wire – understanding AWS classifications can help welding operators know the performance that they will gain from a given product and the way it is best used.

Pure tungsten electrodes (AWS classification EWP) contain 99.50 percent tungsten, have the highest consumption rate of all electrodes, and typically are less expensive than their alloyed counterparts. These electrodes form a clean, balled tip when heated and provide great arc stability for AC welding with a balanced wave.
Welding electrodes In arc welding , an electrode is used to conduct current through a workpiece to fuse two pieces together. Depending upon the process, the electrode is either consumable, in the case of gas metal arc welding or shielded metal arc welding , or non-consumable, such as in gas tungsten arc welding .
