Final answer:
The AWS coding system designates electrodes with specific characteristics. An electrode for all positions with a minimum tensile strength of 80,000 psi and for low alloy steels would likely have a designation that includes an '80' for the tensile strength, such as E8018.
Step-by-step explanation:
An electrode with a minimum tensile strength of 80,000 psi that is suitable for use in all positions for low alloy steel welding would likely be classified under the American Welding Society (AWS) system. The AWS uses a standardized coding system to designate the characteristics of electrodes. For example, an electrode with a specification of E8018 would meet the criteria of having a minimum tensile strength of 80,000 psi, '8' in the code stands for the tensile strength, '1' refers to the electrode's usability in all positions, and the '8' at the end indicates that it is for welding low alloy steels.
