Mr. I understand well that in my question if a qualified welder according API code Apenice B (paragraph 6.3) more requirements (paragraphs B.2 and B.3) is qualified to weld welding according to paragraph 6.3 that is not necessarily according Appendix B, keeping the same essential variables...
[b]A welder is qualified to Appendix B (Paragraph 6.2 and B.2) according to API 1104 code,
This qualified the welder to weld according to paragraph 6.2 keeping all essential variables for the same welder?
A qualified with API 1104 Appendix B (B.2) welder, welding would be qualified according 6.1, I manteniedo the same essential variables, the only difference is the warm (not essential variable)
