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.
