Weld Mapping Software
Turn your isometric and spool drawings into digital weld maps. Pin every weld, capture its records where the work happens, and export an inspection-ready weld map on demand.
A weld map is a piping isometric or spool drawing with every weld joint marked and numbered, tied to a record of how each weld was made and inspected: who welded it, which procedure (WPS) they used, the pipe size, schedule and material, and the visual, NDE and PWHT results. On code work under ASME B31.3, B31.1 or API 1104, the weld map is how an inspector traces any joint back to its paperwork.
Most contractors still build weld maps by hand: marked-up prints in the field, then a spreadsheet weld log rebuilt in the office. Weld mapping software replaces both with one digital map where the joint and its record live together.
Drag in isometric or spool drawings as PDFs. WeldMapper reads the drawing details and suggests weld locations, so you start from your drawing set instead of a blank sheet.
Tap the drawing to place a weld. Joints are auto-numbered, so the numbering on the map and the numbering in the weld log can't drift apart.
Welders log welder, WPS revision, pipe size, schedule, material spec and heat numbers from a phone or tablet, and can attach a short video. Inspectors add visual, NDE and PWHT results to the same joint.
Generate a Weld Map PDF with an ASME B31.3 / IIAR compliance footer, plus a filterable weld log you can export to CSV, whenever the inspector or owner asks for it.
No clean isometric for a field run? WeldMapper includes an isometric drawing builder on a standard 30°/60° iso grid. Run pipe in any iso direction, place ANSI/ASME B16.9 fittings (elbows, tees, reducers, flanges, valves), number the welds, and add continuation markers and P&ID references. PDF drawings and native isos sit side by side in the same project, and the builder computes cut lengths from B16.9 fitting dimensions for a per-spool takeoff.
| Paper & spreadsheets | WeldMapper | |
|---|---|---|
| Building the map | Mark up printed isos by hand, then re-key everything into a spreadsheet. | Pin welds on the drawing once. The map and the weld log are the same data. |
| Keeping it current | The office sees field progress when marked-up prints come back. | A weld is on the map the moment it's logged from the field. |
| Weld numbering | Duplicate or skipped numbers are found at turnover. | Joints are auto-numbered on the drawing. |
| Answering an inspector | Dig through binders to tie a joint to its welder, WPS and NDE report. | Tap the joint and the full record is there. |
| Turnover package | Assembled by hand at the end of the job. | Export the Weld Map PDF and weld log on demand. |
At minimum, a weld map should show every weld joint on the isometric or spool drawing with a unique joint number, and tie each joint to the welder who made it, the WPS used, and its inspection results (visual, NDE and, where required, PWHT). For code work it should also carry pipe size, schedule, material spec and heat numbers so any joint can be traced back to its material and procedure.
Yes. Upload your isometric or spool drawings as PDFs and place welds directly on them. If you don't have a usable iso for a run, you can draw one in WeldMapper's built-in isometric builder, and both kinds of drawing live in the same project.
No. The paperwork problem is the same on a ten-weld tie-in as on a thousand-weld unit: every joint needs a number, a welder, a procedure and an inspection record. A digital weld map pays off fastest for contractors running several jobs at once, where the office otherwise rebuilds weld logs from field markups for each one.
A weld log is the table of joints and their records. A weld map is that same information placed on the drawing, so you can see where each joint physically is. In WeldMapper they are one dataset: pins on the map are the rows in the weld log, and the log exports to CSV.
Yes. Welders and foremen log welds from a phone or tablet by tapping the drawing, entering the pipe specs, and optionally recording a short video. Inspectors and project managers see each weld as soon as it's logged.
