During offshore pre-commissioning you're checking a replacement carbon steel spool after hot work, and you search "verify metallic bonding continuity before commissioning offshore" at 01:30. What do you physically verify first to confirm the metallic bonding state is acceptable for service?

Question

Accepted Answer

Option A would waste time proving insulation where metallic bonding is required and could mask a real continuity issue, Option B tells you nothing about whether electrons can actually move across the joint today, Option C addresses mechanical integrity but doesn't confirm electron sea continuity, Option D directly verifies metallic bonding by checking that free electrons can move across the joint as expected.
