the Welders Performance Qualification Test Record.
4.6
Only test materials that had a Test Material Identification Number shall be
used for qualification testing and shall be recorded to applicant’s Welders
Performance Qualification Test Record There follows a list of the ID letters
will be use and then a full description on implementation.

This is the Subnet Materials Batch Number ID
This is the Subnet Filler Metal Batch Number ID
This is the Specimen Cut from Coupon ID
Generating ID Numbers Requirement:
4.6.1. Subnet Student ID:
Using letters SN + an incremental number. This is the ID number that
will be given to student / CW applicant, for referencing and office data
recording.
4.6.2. Student Test Coupon:
Call this the Coupon ID using a letter X + an incremental number. This
will be given to the student / CW Applicant for each coupon test taken
and will be marked on the coupon / test piece using metal stencil. If
coupon numbers reach X9999, letter and number suffix will be stamp;
e.g. XA-1, XA-2.

Material Batch ID:
Using a letter M + an incremental number start at 01. The ID given to
each batch of base metal delivered to the Facility. When material
arrives it will have a Mill Certificate that states the metal it’s standard
and conforms to X (coupon) like carbon steel pipe, plate, sheet. There
may be more than one batch of material delivered at any time, e.g. 3
x 20ft lengths MS steel pipe 6” diameter with a company X mill cert no
xxx123 5 sheet of plate 10mm thick stainless with a company Y mill
cert xxx9981234555.
The delivered material will be sorted into batches that belong to the
mill certificates.
Using our facility own incremental Material Batch ID for all that
matches any mill certificate. So the 3 lengths pipe would have a
subnet batch no of M1.
The 5 sheets would all have batch number M2.
Each unit in the batch will be stamped or marked.
Each time a unit is divided / cut then the batch number will be
duplicated to all sections divided from the original length.
So if a 20ft length of pipe with a Material Batch ID of M1 is cut into 20
sections then all those 20 sections will be stamped with the same
Material Batch ID (M1) as the original length.
Important: Any material delivered without a supporting qualified Mill
Certificate must not be given a Materials Batch ID but must be
separated from our Testing Material, marked as nonconforming and
shall not be used for AWS Test Coupons.
4.6.4
Filler Material ID:
Using a letter F + an incremental number: Filler material will mostly be
welding electrodes. We will make Purchase Order (PO) for specific
rods. When delivered the filler material will be in batches, each batch
will have a Certificate of Conformance. We will sort the filler material
into batches as per to the certificates and we will label each batch with
our own incremental batch number, e.g. 5 boxes of 10g steel filler
belong to company certificate xxx22232345 we issue our Filler
Material ID (F1) and so on. We place the label F1 on all 5 boxes.

test assembly as an alternate to mechanical testing and shall meet
the acceptance criteria specified in the Performance Test Description
4.13.5
The Welders Identification Number should appear on the result of
examination and testing including x-ray film when radiography is
used. After the test pipe (s) meet the visual acceptance criteria
defined in ASME B31.3 and in case of radiography will be used in
lieu of bend test for pipe coupons. A Radiography Test Request will
be send to Subnets Services Ltd. accredited & authorized NDT Third
Party. Request will be contained a system of identification for the
samples or items to be tested through documents or through
markings, to ensure that there can be no confusion regarding the
identity of the samples or test items and the result of the
measurements made. (see NDE and Destructive Request Form).
4.13.6
The NDT Third Party will pick the samples from the Testing Facility,
but strict precaution shall be taken to prevent damage to the items,
