AS PER SEC. 9
QW-306 Combination of Welding Processes
Each welder or welding operator shall be qualified
within the limits given in QW-301 for the specific welding process(es) he will be required to use in
production welding. A welder or welding operator
may be qualified by making tests with each individual
welding process in separate test coupons, or with a
combination of welding processes in a single test coupon.
Two or more welders or welding operators, each
using the same or a different welding process, may be
qualified in combination in a single test coupon. For
combination qualifications in a single test coupon, the
limits for thicknesses of deposited weld metal, and
bend and fillet testing are given in QW-452 and shall
be considered individually for each welder or welding
operator for each welding process or whenever there
is a change in an essential variable. A welder or welding
operator qualified in combination on a single test coupon
is qualified to weld in production using any of his
processes individually or in different combinations,
provided he welds within his limits of qualification
with each specific process.
Failure of any portion of a combination test in a
single test coupon constitutes failure of the entire
combination.
