Welder qualification to API 1104 20th edition

[cjgrass]

Hello,
If a welder takes a qualification test and passes for company A finishes the job and does not come back to work again for company A for 18 months. Does he need to re-qualify for company A? If so where does it say so in the code?
Thank you for your help

If he was not welded for the period of past 6 months he needs to be re qualified.

QW-322.1 Expiration of Qualification.
The performance qualification of a welder or welding operator shall
be affected when one of the following occurs:
(a) When he has not welded with a process during a
period of 6 months or more, his qualifications for that process
shall expire; unless, within the 6 month period, prior
to his expiration of qualification
(1) the welder has welded with that process using
manual or semiautomatic welding, under the supervision
and control of the qualifying organization(s) that will
extend his qualification for an additional 6 months
(2) the welding operator has welded with that process
using machine or automatic welding, under the
supervision and control of the qualifying organization(s)
that will extend his qualification for an additional
6 months
(b) When there is a specific reason to question his ability
to make welds that meet the specification, the qualifications
that support the welding he is doing shall be
revoked. All

Thank you for the reply. This is an ASME IX requirement i was wondering if API 1104 had anything similar.
