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.
WeldMapper is built to the weld traceability requirements of DOE O 414.1 and ASME NQA-1, and captures documentation to ASME B31.3, B31.1, and BPVC Section IX and V. In practice that means every joint carries the records those standards ask for: the WPS/procedure used, the welder who made the weld and the date it was made, pipe size, schedule and material spec, heat numbers, visual inspection, NDE method and result signed by the inspector who recorded it, PWHT, and any repair — all captured against the weld map as work happens and exportable as an inspection-ready package.
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.
A Welding Procedure Specification is the written procedure that tells a welder exactly how to make a weld so the result meets code. It fixes the essential variables — base metal and thickness range, filler metal and F-number, welding process, position, preheat and interpass temperature, and post-weld heat treatment — inside a qualified range. Under ASME BPVC Section IX a WPS must be supported by a PQR proving those settings actually produce a sound weld. In practice, the WPS is the document an inspector asks for when they want to know why a given joint was welded the way it was.
A PQR is the test record that backs a WPS. Where the WPS says what a welder may do, the PQR records what was actually done on a qualification coupon and how it performed — the as-run variables plus the mechanical test results (tensile, bend, and impact testing where required). One PQR can support several WPSs, and a WPS is only valid inside the range its PQR qualified. WeldMapper stores both, keeping each PQR attached to the procedures it supports so the evidence chain behind a WPS stays intact.
A WPQ — also called a welder qualification record — proves that an individual welder can produce a sound weld under a given procedure. The WPS and PQR qualify the procedure; the WPQ qualifies the person. It records the procedure the welder tested to, the standard (ASME BPVC Section IX, AWS D1.1, or API 1104), the positions and thickness range it covers, and the date. It also has to stay in continuity: under ASME Section IX QW-322 a qualification lapses if the welder has not used that process for six months.
Yes. WeldMapper keeps a tenant-owned WPS registry with full revision history, the PQRs and demonstration records supporting each procedure, and a shared catalog for standard procedures. Welds are tied to a specific WPS revision rather than to the procedure as a whole, so a joint welded under Rev 2 still reports Rev 2 after the procedure is revised to Rev 3 — which is what an auditor needs, and what a single-document approach loses.
You can upload the document. WeldMapper reads an uploaded WPS or WPQ and pre-fills the registry form for review — nothing is written until a person checks the values and saves. That means you can build the registry from the paperwork you already have instead of retyping every card, and a failed or rejected extraction never discards the uploaded file.
WeldMapper cross-checks three things against each weld: that a procedure actually covers the joint as welded, that the welder holds a qualification covering that procedure, and that the qualification is still in continuity. Where a welder holds several qualifications, it scores each and reports the best match rather than the first one it finds. The effect is that a procedure or continuity gap surfaces while the job is running, instead of during the audit.
Yes, and the status is computed rather than stored, so it is never stale. Each welder's qualifications are shown as a green, amber, or red card reflecting whether they are current, approaching a continuity lapse, or expired under ASME Section IX QW-322 — which lapses a qualification six months after the welder last used that process. Project managers and admins can record that a procedure was used today to reset continuity.
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.
