🔍 Key Concepts

• AWS electrode classification system for shielded metal arc welding (what each digit means in E-6010) • Relationship between the first two or three numbers and minimum tensile strength (psi) of the deposited weld metal • How the letter E is used in welding electrode designations

💭 Think About

• What does the letter E at the beginning of 6010 stand for in welding rod numbering? Does it describe the welding process, the position, or something else? • In AWS numbering (like 6010, 7018), which digits tell you the minimum tensile strength, and what unit is it expressed in? • Which digit in 6010 tells you about welding positions (flat only vs all positions), and do any of the choices match that meaning accurately?

✅ Before You Answer

• Verify how many thousands of psi the first two digits in a welding rod number represent (e.g., 60xx, 70xx). • Confirm what the third digit in 6010 indicates (welding position), and see if any option matches that exactly. • Check whether the AWS code ever uses the designation to specify type of electrode holder; if not, eliminate that choice.
