Trace a weld's materials
Every weld drawer has a Traceability section that answers the auditor’s question in one look: where did this joint’s material come from, and can we prove it? It draws the weld’s ancestry as a diagram — the weld, the heats it was made from, each heat’s mill certificate (MTR), and the welding procedure with the WPS revision in force — so you can follow the chain without opening five other screens.
Open it
Section titled “Open it”- Open the ISO’s weld matrix and select a weld to open its drawer.
- Scroll to Traceability.
The panel is read-only. Nothing you do here changes the weld — every node is a shortcut to the record behind it.
How to read the diagram
Section titled “How to read the diagram”The diagram runs left to right in three bands:
- WELD — the weld you’re viewing.
- HEAT · PROCEDURE — the heat for each piece (labelled
P1andP2, with the ASTM grade recorded on the weld), and the welding procedure. - CERT · WPS REV — each heat’s mill certificate, and the WPS revision pinned to the procedure.
A weld made from a single piece simply shows one heat. That is normal — it is not a missing record, so nothing is flagged.
A dashed red node is an honest gap: something that should be on file isn’t. There are three:
| Gap | What it means |
|---|---|
| Heat unmapped | No heat is recorded for piece 1, so the material can’t be traced at all. |
| Mill certificate missing | The heat is recorded, but no MTR is attached to it. |
| Procedure undefined | No welding procedure is recorded for this weld. |
These are the same gaps the weld matrix flags with its ⚠ marker and its Issues lens — the panel never disagrees with the matrix, because both read one shared rule. If the matrix flags a weld, the drawer shows you exactly which link in the chain is broken.
Every gap is also a shortcut to its fix: select the node and MaxTrax takes you to the screen where you’d resolve it (reference data for heats, the procedures list for a missing procedure).
Open a mill certificate
Section titled “Open a mill certificate”Select a mill certificate node to open the document. MaxTrax mints a fresh, short-lived secure link each time, so certificates always open through the current permissions — there’s no stale link to share around.
If your browser blocks the new tab, MaxTrax tells you so rather than failing silently. Allow pop-ups for MaxTrax and select the node again.
Repair succession
Section titled “Repair succession”Below the ancestry, a weld that has been repaired shows its repair succession — the full chain
from the original through each repair (for example 01 → 1R → 1RC). The weld you’re currently
viewing is ringed. Select any other member to jump straight to that weld’s drawer, so you can walk a
repair history without leaving the matrix.
A weld that has never been repaired says so plainly.
When lineage isn’t available
Section titled “When lineage isn’t available”Traceability is an online view — the material chain isn’t carried on your device for offline work. If you’re offline, or the ISO’s data hasn’t loaded yet, the panel says “Connect to load lineage” instead of showing an empty or all-gap diagram. A blank chain would read as “this weld has no traceability”, which is a very different (and much worse) claim than “we haven’t loaded it.”
Similarly, while heat reference data is still loading, certificate nodes read “not yet loaded” rather than being hidden — MaxTrax never quietly hides a certificate that exists, and never invents a gap it can’t prove.
