Which statement best describes the success criterion for a welder qualification test?

• A. The welder's speed must exceed a threshold.
• B. Welds must meet the specified acceptance criteria for the process and position.
• C. Only visual appearance is considered.
• D. Equipment cost is the sole factor.

Answer: (B)

The key idea is that a welder’s qualification is about producing welds that meet the required quality standards for a given process and position. The success criterion is that the welds on the test coupons must meet the specified acceptance criteria defined by the applicable welding code. Those criteria cover things like geometry, surface condition, and the presence or absence of defects, often including required mechanical or nondestructive tests. When the test welds satisfy all those criteria, the welder is qualified for that process and position; speed, visual appearance alone, or cost considerations don’t determine qualification.
