Isometric to weld log
From isometric drawings to a validated weld log
Building a weld log by hand from an iso package means hours of reading title blocks, counting welds and cross-referencing the BOM. IsoLog does that extraction and the cross-check, and a weld mapper reviews every row before it reaches you.
How it works
- Upload the iso PDFs, the BOM, and your log template or numbering rules
- Weld data is pulled from every sheet: line number, weld number, size, schedule, material, joint type
- Each weld is checked against the BOM and across the package for duplicates, gaps and spec conflicts
- A weld mapper reviews the log and the discrepancy report, then it is delivered within 48 hours
Why the cross-check matters
A schedule called SCH 80 on the iso and SCH 40 on the BOM is a small line on paper and a rework ticket in the field. Catching it before fit-up is cheaper than catching it at NDE or turnover.
Delivered in your format
Logs come back in Excel, laid out to match your existing template, with a separate discrepancy sheet your QC lead can work through and close out.
Common questions
- What file formats do you accept?
- PDF isometrics are preferred. BOMs and templates can be PDF, Excel or CSV. Up to 100 MB per file.
- Can the log go straight into our weld tracking software?
- Yes. The log is delivered in Excel mapped to your template, which imports into most weld tracking and QC systems.
- What does the BOM cross-check catch?
- Schedule and size mismatches between the iso and the BOM, material grade conflicts, missing or duplicate weld numbers, and welds that appear on one sheet but not the matching continuation.
- Are our drawings kept confidential?
- Yes. Files are stored privately, seen only by IsoLog, never shared or reused, and deleted on request after delivery.
