QW-200.4 Combination of Welding Procedures<br />
(a) More than one WPS having different essential, supplementary essential,<br />
or nonessential variables may be used in a single production joint. Each WPS<br />
may include one or a combination of processes, filler metals, or other<br />
variables. Where more than one WPS specifying different processes, filler<br />
metals, or other essential or supplementary essential variables is used in a<br />
joint, QW-451 shall be used to determine the range of base metal thickness<br />
and maximum weld metal thickness qualified for each process, filler metal, or<br />
set of variables, and those limits shall be observed. Alternatively, qualification<br />
of WPSs for root deposits only may be made in accordance with QW-200.4(b).<br />
When following a WPS that has more than one welding process, filler metal,<br />
or set of variables, each process, filler metal, or set of variables may be used<br />
individually or in different combinations, provided<br />
Charlie Chong/ Fion Zhang
(1) the essential, nonessential, and required supplementary essential<br />
variables associated with the process, filler metal, or set of variables are<br />
applied<br />
(2) the base metal and deposited weld metal thickness limits of QW-451 for<br />
each process, filler metal, or set of variables are applied<br />
(b) For GTAW, SMAW, GMAW, PAW, and SAW, or combinations of these<br />
processes, a PQR for a process recording a test coupon that was at least<br />
½ in. (13 mm) thick may be combined with one or more other PQRs<br />
recording another welding process and any greater base metal thickness.<br />
In this case, the process recorded on the first PQR may be used to<br />
deposit the root layers using the process(es) recorded on that PQR up to<br />
2t (for shortcircuiting type of GMAW, see QW-404.32) in thickness on<br />
base metal of the maximum thickness qualified by the other PQR(s) used<br />
to support the WPS. The requirements of Note (1) of tables QW-451.1 and<br />

QW-431 General<br />
The following F-Number grouping of electrodes and<br />
welding rods in table QW-432 is based essentially on their<br />
usability characteristics, which fundamentally determine<br />
the ability of welders to make satisfactory welds with a<br />
given filler metal. This grouping is made to reduce the<br />
number of welding procedure and performance qualifications,<br />
where this can logically be done. The grouping does<br />
not imply that base metals or filler metals within a group<br />
may be indiscriminately substituted for a metal that was<br />
used in the qualification test without consideration of the<br />
compatibility of the base and filler metals from the standpoint<br />
of metallurgical properties, postweld heat treatment<br />
design and service requirements, and mechanical<br />
properties.<br />

ESW<br />
Electroslag welding (ESW) is a highly<br />
productive, single pass welding process<br />
for thick (greater than 25 mm up to<br />
about 300 mm) materials in a vertical or<br />
close to vertical position. (ESW) is<br />
similar to electrogas welding, but the<br />
main difference is the arc starts in a<br />
different location. An electric arc is<br />
initially struck by wire that is fed into the<br />
desired weld location and then flux is<br />
added. Additional flux is added until the<br />
molten slag, reaching the tip of the<br />
electrode, extinguishes the arc. The<br />
wire is then continually fed through a<br />
consumable guide tube (can oscillate if<br />
desired) into the surfaces of the metal<br />
work pieces and the filler metal are then<br />
melted using the electrical resistance of<br />
the molten slag to cause coalescence.<br />
