What does a welding engineer check before approving a consumable?
They check the classification against the standard their procedure references, the all-weld-metal mechanical properties, and whether the consumable carries the approvals their code requires. In coded work an unapproved consumable cannot be used regardless of how it performs.
A welding engineer is qualifying a procedure and needs a consumable whose paperwork will satisfy the inspection authority.

Questions suppliers ask
Which approvals should be listed on a product page?
The ones your customers' codes actually require, each with the approval body and certificate reference. A list of logos is not usable by a welding engineer preparing a procedure, and the specific approvals are what determine whether your consumable can be used at all.
Should typical or guaranteed mechanical properties be published?
Publish typical all-weld-metal values with the test conditions, and be clear that batch certificates carry the actual results. Welding engineers understand the distinction and use typical values for selection and batch certificates for acceptance.
How much application guidance belongs on the site?
A good deal. Parameter ranges, position guidance, preheat and interpass recommendations and storage instructions are what a fabricator needs to get your consumable to perform. Suppliers who publish it get fewer complaints and more repeat orders than those who publish only a specification.
Check which documents and standards your buyer needs; requirements vary by market, customer and contract.
