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.

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 prefix "E" designates an arc welding electrode. The first two digits of a 4-digit number and the first three digits of 5-digit number indicate minimum tensile strength. For example, E6010 is a 60,000 psi tensile strength electrode while E10018 designates a 100,000 psi tensile strength electrode.

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 ...

A key component in the welding process is the electrode or filler metal used in making the welded connection. Metal from the electrode is introduced in the joint through the welding process, and this metal must be of the same or better chemical and mechanical properties of the materials being welded.

GMAW (MIG Welding) electrode specification August 12, 2017 May 27, 2020 Sandeep Anand 7 Comments filler metal, gas welding, GMAW, MIG, mig welding GMAW (MIG welding) electrodes are designated by some letters and numbers such as ER70S-6, ER90S-6 and E308L etc.

Jul 13, 2016· An electrode or a welding rod is a wire which is made up of wire and is coated. The electrode is made up of materials which are similar to that of the metals chosen to be welded. Among all the other types of welding, the stick electrode welding is considered to be portable, simple and reliable.

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

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.

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.

**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.

Ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30 percent tungsten and 1.80 to 2.20 percent cerium and are referred to as 2 percent ceriated. These electrodes perform best in DC welding at low current settings but can be used proficiently in AC processes.

Electrodes are issued with certificates (I.S.I.) stating the name of the manufacturer, electrode classification type and size, number of the batch, core wire grade, number of the standard or chemical analysis of core wire, date of the manufacture, and test results etc.

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.

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning amber (from which the word electricity is derived), and hodos, a way..
