Decoding AWS A5.18 ER70S-6 Meaning: A Comprehensive Guide.
When it comes to welding, understanding the various codes and classifications is essential to ensure the quality and integrity of the welds. One such code that is commonly used in the welding industry is AWS A5.18 ER70S-6. In this comprehensive guide, we will break down the meaning of this code and its significance in welding applications.
AWS A5.18 ER70S-6: Breaking Down the Code.
AWS A5.18 is the specification for carbon steel electrodes and rods for gas shielded arc welding. ER70S-6, on the other hand, is the classification assigned to a particular type of electrode or rod. Let's break down what each part of the code represents:
- "ER" stands for "Electrode/Rod.".
- "70" indicates the minimum tensile strength of the weld metal in ksi (kilopounds per square inch).
- "S" stands for "Solid" wire.
- "6" refers to additional elements added to the welding wire, such as silicon and manganese.
In summary, AWS A5.18 ER70S-6 specifies a solid wire electrode with a minimum tensile strength of 70 ksi, suitable for gas shielded arc welding of carbon and low-alloy steels.
Significance of AWS A5.18 ER70S-6 in Welding.
