The AWS organization is for the duty of classification of a welding rod or electrode after production. The American Welding Society (AWS) is the organization that is responsible for publishing the requirements for a wide range of welding filler metals. The welding industry makes use of these norms and regulations to categorize various types of welding electrodes, which are known as the specifications. A defined classification system is utilized by AWS in order to assist in the identification of rod electrodes. The classification is represented by numbers and letters that are inscribed on the side of the rod electrode. These numbers and letters each stand for a different property of the electrode. The AWS system operates as follows for the electrodes made of mild steel, as was explained earlier. The word "electrode" is represented by the letter "E." The first two digits indicate the minimum tensile strength of the weld that is produced, which is measured in pounds per square inch (psi). 
For instance, the number 70 in an E7018 electrode denotes that the electrode will create a weld with a minimum tensile strength of 70,000 pounds per square inch (psi). The weld location at which the electrode can be employed is indicated by the third digit in the number. For instance, a value of 1 indicates that the electrode can be used in any position, while a value of 2 indicates that the electrode can only be used in the flat and lateral positions for fillet welds. The type of coating and the type of welding current (alternating current, direct current, or both) that can be utilized with the electrode are both represented by the fourth digit. When a manufacturer affixes the AWS standard and classification to an electrode package or places the classification on a product, they are certifying that the product satisfies the requirements of the classification by stating that the product meets those requirements. With the use of this method of identification, the welder may be certain that the appropriate electrode is being used for the metal that is going to be welded. Since AWS does not carry out any testing on its own, the manufacturer is the one who is responsible for carrying out the tests that are required for this designation. The results that are reported on the AWS typical certificate come from the welding tests and the laboratory analysis. These are completed under a consistent set of conditions and to a stringent set of standards outlined in the specification that covers this particular consumable group. These results are then reported on the AWS typical certificate. 
Welding electrode aws classification
The classification of a welding rod or electrode according to its use and its type is one of the AWS duties. Electrodes are produced for different purposes and types of welding and are classified by a five-digit type number E7011-M. Each number and letter corresponds to a piece of information, including recommended welding position, tensile strength, and penetration depth. "E" in the classification denotes an electrode. Getting good results with every weld depends on having the right tools and filler metal, as well as the skills of the welder to do the job efficiently and accurately. Productivity and cost savings are important in an industry where competition can be fierce. In addition to proper welding technique, it is also helpful for the welder to have a clear understanding of the welding processes required for the application and to know the classification of the filler metals used. The American Welding Society (AWS) classification of filler metals provides valuable information about their usefulness, including what materials they are best suited for and how to use these products for maximum performance. They also give an idea of the mechanical properties that a particular filler metal may have. 
In other words, the AWS classification sets the standard for filler metals, so there is a common understanding or awareness of what a particular stick electrode or wire will do. These standards are then used by filler metal manufacturers in their product formulations, providing greater consistency between manufacturers in terms of welding, chemistry and mechanical properties. If a primary solder supplier runs out of a particular solder or has supply issues, a secondary manufacturer will offer a product with the same AWS classification that offers similar chemical and mechanical properties—even when soldered. For example, wetting action or arcing may vary between products with the same classification from different manufacturers, but the overall utility and capability is the same. Knowing the AWS classifications helps welders when they are unfamiliar with a product and don't necessarily know what it will do under trade names. With this information, they can view the classification and understand its properties - how it works and whether it provides hard-to-disperse hydrogen, for example. The key information provided by the AWS classification are identifiers that indicate: 1) Is the product rod electrode, solid wire, or tubular wire? 2) The situation in which it will be used 3) Strength rating 4) Its chemical composition and composition Examples of these important classifications are listed below along with the corresponding charts for the three AWS General Specifications for Carbon Steel Filler Metals. These diagrams and explanations help to demonstrate the key differences between the classifications and provide insight into other alternative identifiers that may be just as important to understand. Note that the AWS classifications differ in their nomenclature between rod electrode, solid wire, and wire. The following are examples of products with specifications: AWS A5.1 (carbon steel electrode for gas arc welding), A5.18 (carbon steel electrode and rod for gas arc welding), and electrode A5.20 (carbon steel for flux-cored arc welding), are all filler metals that can be used for various operations with mild steel. These include general manufacturing, rolling stock manufacturing, shipbuilding, heavy equipment manufacturing, and more. 
Welding electrode production
The welding rod or electrode manufacturing and production is very important because it is a very huge industry that needs proper equipment like welding rods and electrodes. The behavior and properties of electrodes can be reduced not only to the chemical composition of their components but also to the origin of these materials, as well as to the breakdown and operation performed on them. In general, electrode materials are divided into 6 main categories: Slag-forming material in the form of mineral stones. Examples are titanium rock, manganese rock, fluorspar, iron oxide, and some silicates. Shielding gas components such as starch, sawdust, charcoal, flour, or cellulose. Reducing or deoxygenating agents are used to reduce certain oxides. Such as ferromanganese, ferrochromium, ferrotitanium, and flake aluminum. Alloy additives were added to the coating to obtain the desired final weld structure. Adhesives that make the coating sticky and adhere to the wart. Some base metal powder is also added for some electrodes. Because it increases sedimentation rate, efficiency, and productivity. For example, some iron is added to the coating of a steel electrode. Finally, after selecting the coating material and mixing it in the mixer, a pasty material is formed, called the "electrode flower". This material is pressed onto the brain rods of the electrodes using special presses. And after the electrode has completely dried in a drying oven, it is ready for use or packaging. Over a century ago, welders joined two metal surfaces using electric current to melt a metal rod. This rod is now called the welding electrode. 
Stages of manufacturing welding electrodes:
- Workshop for the production of metal electrode rods
The base metal of the electrode enters the factory in the form of a roll. And the diameter of the wire roll used is 5~6mm. These rolls are first removed and then transferred to a drawing machine, where the wire is cut to the required diameter of 2.3 mm. After washing and unloading, these rolls are automatically cut into 400mm long metal wires by a cutting machine. These metal wires are transported to the pallet device and the electrode rod feeder by a forklift.
- Department for the production of electrode coatings
First, the coating materials are received from the warehouse and, after cooling in an electric screening machine, each is stored in a metal container. Then weighed according to the recipe and placed in a mixer. This recipe machine can work both dry and wet. Charging the device at each stage is 120 kg, and the time of each charge is 4 minutes. The finished mixture is now poured into the cylinders of the coating machine, then it can be compacted by hand and used on a separate machine to press, compact, and aerate the powder.
- Stages of manufacturing electrodes
At this stage, the desired amount of coating is automatically applied to the metal wire in the electrode coating machine. The productivity of coated electrodes of this device is not less than 500 kg per hour. Press pressure not less than 200 bar. The electrodes move along the conveyor belt to the cleaning machine to clean it of particles and dirt. The electrode is now placed in an oven and dried at 200°C. Then it is taken out of the oven and the necessary marking is applied using a marking machine. And finally, it is packed and sent to the warehouse.
