[MW:32065] Welder Qualification API 1104

By Materials & Welding
Dear experts,

I am qualifying 2 welder on 20" pipeline. One half welder by welder A and other half welder B.  The RT result shows Welder A side failed and Welder B side passed.
Query : Both the welders are rejected as the coupon has failed or should I consider welder A and welder B passed.

Any code reference or interpretation on similar case will be helpful.
