Show where joints may appear
Mark visible seams and preferred joint locations on the drawing. Ask the fabricator to propose the weld and finishing sequence. A requirement for a seamless visual result should be reviewed against the actual geometry and selected finish.
Separate cleaning from appearance matching
Outokumpu explains that fabrication defects and weld-related oxides can affect surface quality and corrosion performance. Their appropriate removal is a fabrication matter. Matching a decorative texture or colour is an additional appearance requirement, not automatically achieved by making the joint clean.
Approve the difficult detail
Request a representative corner or welded section before releasing a repeated component. Ask how the final colour is applied and whether later local repair will be visible. Keep specialist chemical treatment within a qualified fabrication process rather than suggesting improvised site cleaning.
| Decision | Put this in writing |
|---|---|
| Joint location | Identify visible and concealed seams. |
| Surface treatment | State the required final condition. |
| Appearance | Approve a representative restored joint. |
Put the detail to work.
A polished decorative frame includes a visible welded corner. Request a corner sample showing the final surface after the full finishing sequence. Review it under the intended lighting and record whether the joint remains visible. If the appearance is not acceptable, discuss a revised detail or process before production. An agreement to polish the weld is too vague to replace a reviewed physical result.
Before you enquire
- Include finishing in the quoted scope.
- Review the fabrication sequence.
- Retain the accepted joint sample.
