Filler metal certificate requests, read against the lot on your packing slip.

The request rarely says enough. It may name a PO from months ago, a wire diameter, or only the project the wire went into. Someone looks up the order, finds the lot or heat on the pick ticket or packing slip, and goes to the maker's site, a shared folder or a sales rep for the document covering that lot. Then they read the customer's PO or the job's specification to see what it really wanted: a certificate of conformance, a test report tied to the lot, an EN 10204 type, or a line about domestic content.

For the test, AI reads copies of those files and drafts a certificate review sheet for each request: AWS classification and size, the lot or heat that shipped, the certificate type asked for, the PO's requirements as written, the maker's document matched to that lot, and whatever is missing. A person at the branch checks it and decides what goes out. Nothing leaves on a draft.

A certificate can be narrower than its title. One maker's published lot document for submerged arc wire is headed Certificate of Analysis. It gives lot and heat numbers, AWS A5.17 and ASME SFA5.17, the class EM12K, and EN 10204 Type 3.1 certification, qualified in a parenthesis as covering actual chemistries only. The customer, P.O., marked-for, pack slip and pounds-shipped lines sit empty on the published copy. In a 2009 thread on a public materials and welding forum, a client that required 3.1 on consumables turned down a set with chemistry at 3.1 and mechanical properties at 2.2. The standard's 2004 revision cut its types to 2.1, 2.2, 3.1 and 3.2, so a PO template still asking for 3.1B names a type that revision dropped. The draft quotes the type and the wording printed on each document and doesn't round up.

How much testing was bought is a term of the purchase. AWS A5.01, the society's procurement guidelines for consumables, gives a buyer a way to state a lot classification and a testing schedule. One maker's aluminum welding guide walks through it for aluminum wire and rod: lot classes S1 to S4, with S1 being the lot as the electrode maker's own quality manual defines it, and schedules F through K, where F is the maker's base standard and J puts each lot shipped through the usability test in AWS A5.10. If a PO named a class or schedule, a document for a standard lot may not answer it. The draft shows what the PO asked for and what the document shows, side by side.

Wire often gets certified as half of a pair. AWS classifies submerged arc filler as an electrode and flux combination, under A5.17 for carbon steel and A5.23 for low alloy, so a class line naming only the wire doesn't show the pairing a fabricator's procedure uses. The Federal Highway Administration's Bridge Welding Reference Manual has reviewers of gas-shielded procedures confirm that the electrode and gas combination appears on the maker's certificate of conformance. For fracture-critical work it also has them confirm that the certificate lists diffusible hydrogen or coating moisture testing. The draft notes each item the process calls for and whether the document carries it.

Owners write conditions of their own. Texas DOT's 2024 Item 448 on structural field welding calls, when requested, for a current Certificate of Conformance with acceptable Buy America wording, tests run on electrodes of the same class, size and brand made by the same process from the same materials, and resubmittal every 12 months. The FHWA manual says the Bridge Welding Code looks for a maker's quality program approved by one of three named bodies, falls back to heat and lot testing otherwise, and notes that a few owners keep approved lists. Canadian work adds CSA W48: the Canadian Welding Bureau's notice on false claims cites CSA S16 on electrodes meeting W48 and says only consumables that have kept their certification may advertise it, under the maker's trade name designation and point of manufacturing. These are named so your reviewer can check the draft's reading; nothing here is legal or engineering advice.

What your reviewer reads for. Usually the inside sales lead or branch manager who answers these requests, your reviewer checks that the lot came from that shipment and not the order before it, that the document fits the classification, size and lot, that the certificate type was read correctly, and that every gap stayed a gap. Choosing a filler metal is no part of this test. It reads what was sold and what the paper says about it.

When your reviewer says yes against the success criteria, new certificate requests get the same review sheet for about 30 days.

A qualified person at the branch reads every sheet and sends every certificate. A request the draft couldn't match waits for them.
