Autogenous Welding: No Added Filler Does Not Mean Automatic Operation

Keep two independent fields

Linde describes TIG operation as autogenous when it uses no added filler, or with separately supplied filler. Automation is a different process-description field. Primary reference: Linde process description.

A proposal can therefore state how material enters the joint separately from how movement and current are controlled. Preserve both entries; translating autogenous into automatic would create information the word does not supply.

Compare invented process records

Imagine fictional record A describes a manually controlled joint with no added filler. Record B describes mechanized movement and separately supplied filler wire. Calling B autogenous solely because movement is automated would misclassify its material condition.

Likewise, manually performed A does not acquire filler merely because an operator is present. These deliberately contrasted records describe documentation logic and do not establish weld chemistry, suitability or a particular production method.

Review a complete proposal

Create separate columns for added filler, filler identity when applicable, movement/control method and parent material. Use an explicit none-declared entry rather than a blank when the route intentionally excludes filler.

Ask how the actual process achieves and verifies the required joint under that condition. The absence of filler is not a complete quality specification. Keeping the material and automation fields independent lets a buyer request the missing evidence without rejecting or approving a route from one ambiguous adjective.
