Check four specifications separately
| Check | Information needed | What not to assume |
|---|---|---|
| Welding process | The specified process from the work documentation, qualified welding procedure specification or machine documentation | A wire, a stick electrode and a rod are not interchangeable simply because their material descriptions are similar. |
| Base material | The exact material designation of both components and the requirements for the joint | “Steel” or “aluminium” is not a complete material specification. |
| Consumable | Full classification or manufacturer designation from the approved selection, including the required variant | Dimensions that fit the machine do not establish suitability for the base material and process. |
| Machine and feed system | Approved diameter, packaging format and all feed or mounting components specified in the machine instructions | The same external diameter or a compatible spool does not replace technical approval of the consumable. |
Example: replacing an empty wire spool
Do not copy only the diameter and spool dimensions. First, check the specified process and exact base material combination against the approved consumable selection. Record the full classification and variant from that selection. Then consult the machine instructions for the wire diameter, packaging format and corresponding feed components. Compare pack quantity and price only once both technical suitability and machine compatibility have been established.
What else belongs on the shopping list
Shielding gas, flux, polarity, contact tip, wire guide and other wear parts may depend on the process, consumable and machine. Take these details only from the welding procedure specification and manufacturer documentation applicable to the specific combination. This category comparison does not replace either the specification of a welding process or welding instructions.
