(OP)
Hi,
Refer to API 1104,
6 Qualification of Welders,
6.2 SINGLE QUALIFICATION
6.2.2 Scope
c. A change of filler-metal classification from Group 1 or 2 to Group 3 or from Group 3 to Group 1 or 2 (see Table 1)

So, if a welder carried out a test using Group 1 filler, did he qualified for Group 2?

How about Group 4, 5, 6, 7, 8 & 9? If the welder carry out using filler Group 4 to 9, did he only qualified for the tested filler or for all Group?
