I mentioned revising the WPS because both 6010 and 7010 are assigned/grouped as F3, so it is permitted if the WPS permits both or either electrode to be used. Staying with the theme for the WPS, was the WPS specific to the performance test given?

The individual tasked with supervising the performance test fell down on the job of verifying the test was performed within the parameters of the WPS. Was the groove angle acceptable, was the root opening within allowable limits, was the coupons to correct base metal specification and grade? Did the welder stay within the permissible ranges for voltage, current, travel speed? Using the incorrect electrode is kind of a big deal, what else was missed?

Are there steps that can be taken to "error proof" the process such as developing a WPS specific to the performance test being administered? Can a check list be used to reduce the likelihood important steps will be missed or a check of the welding parameters could be overlooked? If the checklist included or required the test supervisor to record actual voltage and amperage ranges used and perhaps the travel speed, there would be less opportunity for the welder to weld outside the ranges listed by the WPS. Just thinking out loud. 

I agree, we all make mistakes. My wife keeps a couple of three ring binders to record and compile all my mistakes so she can remind me of them when it suits her needs.
