To qualify for the FW classification, is a stop and restart required?

• A. Yes
• B. No
• C. Not specified
• D. Only for certain joints

Answer: (A)

In FW (field welding) qualification, you need to show you can handle interruptions like stopping the weld and then restarting. This isn’t just a test of how you lay a bead from start to finish; it’s about your ability to re-strike the arc, re-establish the heat, maintain the correct travel speed and angle, and resume producing a sound weld after a pause. Demonstrating a proper stop and restart ensures the weld remains continuous and free of defects when work is interrupted in real field conditions.

That’s why a stop and restart is required for FW qualification—the test specifically assesses this capability. It isn’t optional or limited to certain joints only; the requirement applies to the FW qualification scenario to reflect typical field work realities.
