Final answer:
The minimum tensile strength of a class RG65 welding rod depends on the specific standards and specifications for that class of welding rod.
Step-by-step explanation:
The minimum tensile strength of a class RG65 welding rod would depend on the specific standards and specifications for that particular class of welding rod. The tensile strength refers to the maximum amount of stress the rod can withstand without breaking or deforming. Different welding rod classes have different tensile strength requirements based on the intended application and the type of metal being welded.
For example, in the American Welding Society (AWS) specification for welding rods, the tensile strength requirements for different classes of welding rods are specified. The tensile strength can range from around 60,000 pounds per square inch (psi) to over 100,000 psi for various classes of welding rods.
It is important to refer to specific industry standards and specifications to determine the minimum tensile strength for a class RG65 welding rod.
