What is the meaning of AWS A5 1?
What is the meaning of AWS A5 1?
AWS A5.1/A5.1M, 14th Edition, 2012 – Specification for Carbon Steel Electrodes for Shielded Metal ArcWelding. This specification prescribes requirements for the classification of carbon steel electrodes for shielded metal arc welding.
What is 316L welding rod used for?
316L electrodes are used for welding 18\% Cr–12\% Ni–2.5\% Mo stainless steels where the corrosion-resistant qualities of AISI 316L are required. This electrode has a high deposition rate and produces a weld deposit with fine bead appearance and exceptional crack-resistance.
How are stainless electrodes identified?
The welding rod electrode identification system for stainless steel arc welding is set up as follows: E indicates electrode for arc welding. The first three digits indicated the American Iron and Steel-type of stainless steel. The last two digits indicate the current and position used.
What is the AWS filler metal specification for carbon steel?
AWS Filler Metal Specifications by Material and Welding Process
| SMAW | FCAW | |
| Carbon Steel | A5.1 | A5.20 | A5.36 |
| Low-Alloys Steel | A5.5 | A5.29 | A5.36 |
| Stainless Steel | A5.4 | A5.22 |

What is AWS classification?
AWS Classification AWS stands for American Welding Society and this classification is widely used in the merchant marine. In this, standard electrodes for different applications are numbered such as E6010, E6011, E6013, and E7018 etc.
What do the numbers on electrodes mean?
The first two digits represent the resulting weld’s minimum tensile strength, measured in pounds per square inch (psi). The fourth digit represents the coating type and the type of welding current (AC, DC or both) that can be used with the electrode.
What is AWS filler metal classification?
A filler metal classification provides details about a product’s characteristics and usability, including the type of filler metal, allowable welding positions, tensile strength, shielding gas (if needed), and chemistry/composition.
How do I choose metal filler?
There are seven key factors to consider when selecting a filler metal: The base material to be welded, the welding position, regulatory specifications and codes, design requirements, shielding gas, post-weld heat treatment, and welding equipment.
