Distinguish wire, rod and electrode
Continuous wire, filler rod and covered electrode are different product forms. State the required form explicitly rather than relying on a general request for welding rod.
Identify the alloy and classification
Provide the required grade, consumable classification or existing product designation. Where a procedure controls the work, include its consumable requirements. Do not treat similar trade names as confirmed equivalents.
Describe the work
Say whether the material is for joining, buildup or hardfacing. Identify the base material and intended welding process, together with the applicable procedure or specification.
Specify dimensions and packaging
For wire, include diameter, solid or cored construction where required, and spool or package requirements. For rods, include diameter, length and quantity.
Keep the approval requirements explicit
Include required test records, certifications or other acceptance documents in the inquiry. Confirm product suitability through the applicable specifications and responsible parties before ordering.
