Post the whole sentence, the phrase could mean too many things without the surrounding words.

Thank you first.
The sentence is as follow:

QW-180 FILLET-WELD TESTS
QW-181 Procedure and Performance
Qualification Specimens
QW-181.1 Procedure. The dimensions and preparation
of the fillet-weld test coupon for procedure qualification
as required in QW-202 shall conform to the
requirements in figure QW-462.4(a) or figure QW-
462.4(d). The test coupon for plate-to-plate shall be cut
transversely to provide five test specimen sections, each
approximately 2 in. (50 mm) long. For pipe-to-plate or
pipe-to-pipe, the test coupon shall be cut transversely to
provide four approximately equal test specimen sections.
The test specimens shall be macro-examined to the
requirements of QW-183.
QW-181.1.1 Production Assembly Mockups.
Production assembly mockups may be used in lieu of
QW-181.1. The mockups for plate-to-shape shall be cut
transversely to provide five approximately equal test specimens
not to exceed approximately 2 in. (50 mm) in
length. For pipe-to-shape mockups, the mockup shall be
cut transversely to provide four approximately equal test
specimens. For small mockups, multiple mockups may
be required to obtain the required number of test specimens.
The test specimens shall be macro-examined to
the requirements of QW-183.

The word of plate-to-shape is in the item QW181.1. Thank you

I believe the shape referred to here means structural shape such as a wide flange, I-beam, angle or channel.
