Weld Documentation & Compliance
How piping contractors use WeldMapper to document welds, prove ASME B31.3 / API 1104 compliance, and take off spools — from the field to the final package.
Weld tracking software is the digital replacement for paper weld maps and spreadsheet weld logs. Instead of marking up printed isometrics and re-keying data in the office, you upload your drawings, drop a pin on each weld location, and capture the weld's details — welder, procedure, pipe spec, inspection results — against that joint. The result is a complete, searchable digital weld map where every weld has a full audit trail from the field to the final compliance package.
WeldMapper gives every weld a complete audit trail: the WPS number used, the welder who made it, the joint number, visual inspection results, NDE/RT results, and PWHT status. Because that data is captured against the weld map as work happens, you can produce an inspection-ready weld map and traceability report on demand instead of assembling it by hand before an audit. WeldMapper's exports carry an ASME B31.3 / IIAR compliance footer, and its free pre-inspection checklist is aligned to ASME B31.3 and API 1104.
Per weld joint, WeldMapper tracks the WPS/procedure, welder, pipe size, schedule and material spec, weld type, visual inspection, NDE/RT results, PWHT, repairs, and a live status (open, in progress, complete, or rejected). Every joint is auto-numbered, and inspectors can review and update results in real time, so the record stays current instead of being reconstructed at the end of the job.
Yes. Welders tap the drawing to place a weld, enter the pipe specs, and can record a short video — all from a phone or tablet on the jobsite. There are no paper weld logs and no end-of-day paperwork; the weld is on the digital map the moment it's logged, and the office sees it immediately.
Yes. You upload your isometric or spool drawings, drop pins on the weld locations, and build a complete digital weld map — no paper, no spreadsheets. Project managers and inspectors get real-time visibility into weld progress across every project instead of waiting for marked-up prints to come back from the field.
Yes. WeldMapper includes an in-app isometric drawing builder on a standard 30°/60° iso lattice, so superintendents can draw isos directly instead of hand-drawing and transposing into Bluebeam. You run pipe in any iso direction, place ANSI/ASME B16.9 fittings (elbows, tees, reducers, flanges, valves, and more), number welds, and add continuation markers and P&ID references. PDF drawings and native isos live side by side on the same project.
WeldMapper computes cut lengths from published ANSI/ASME B16.9 fitting dimensions. You enter a dimension as center-to-center, end-to-end, or point-to-point, and it subtracts the correct center-to-face allowance for the fitting at each end and adds your weld gap (default 1/16"). The result is a per-spool takeoff you can export, so fabrication cut lists come straight off the iso instead of a separate manual calc.
WeldMapper produces Weld Map, Takeoff, and Material Requisition PDFs (with an ASME B31.3 / IIAR compliance footer) and a filterable weld log you can export to CSV — all available today. A Procore connector for drawings, timesheets, and inspection push is in development for Pro plans.
Because every weld is logged with a timestamp and the crew behind it, WeldMapper reports welds-per-man-hour in real time. Project managers can see productivity across projects, spot bottlenecks early, and back up progress and manpower conversations with data instead of estimates.
WeldMapper is built for piping, mechanical, and industrial contractors doing process-piping and pipeline welding. It has role-based access for welders (log their own welds), foremen (manage team welds and isos), inspectors (read-only QA/QC review across the company), project managers (create and manage projects), and admins. If your team documents welds for ASME/API compliance, it's built for you.
