Frequently asked questions.
Short answers about the tools, the subscription, data security and cut-on-demand. If your question is not here, write to us.
Getting started and sign-in
How do I start?
You can use the tools right away, without registration; use and printing are free. To save your work, create a free account.
Do I need an account for the tools?
No. All tools and the PDF drawing export are free even without signing in. A free account gives you one project with a smaller library; the paid subscription removes the limits and adds the export of the full dossier.
How do I sign in or reset my password?
You sign in with an email and password. If you forget the password, use the reset link — we send a confirmation link by email, and it also works if you open it on another device.
How Weldmaster works
How do I document welding in Weldmaster — step by step?
The thread runs: drawing → weld → WPQR → WPS → welder → NDT → dossier. Upload a PDF drawing, mark the welds on it, give each a procedure (WPQR/WPS), assign a qualified welder and — where required — an NDT test. Once everything is linked, export a technical dossier with full traceability.
Why is the drawing the starting point?
The drawing is the anchor of the documentation: every weld lives on its drawing, so all data (procedure, welder, NDT, heat number) is tied to a concrete location in the structure. You upload a PDF and the tool adds a markup layer over it.
How do I mark a weld on the drawing?
On the workbench (a desktop tool) you click the weld location and pick the weld type; the symbol follows ISO 2553. You enter the dimensions (throat/leg, length), and where needed the position and process. The tool checks conformity with the chosen qualification as you go (green/yellow/red).
What is a WPQR and how do I get one?
A WPQR is the welding procedure qualification record (EN ISO 15614-1): the procedure is qualified with a test piece witnessed by an examiner or examining body (an independent party). It is not a certificate, and Prokon does not issue it — Prokon only computes the range of qualification from the test-piece data (which thicknesses, positions and materials the WPQR covers) and stores existing WPQRs in your library.
What is a WPS and where does it come from?
A WPS is the welding procedure specification — the parameters the welder actually uses. Prokon builds it automatically from the linked WPQR and the weld geometry; you can adjust the values, and the system warns if they fall outside the qualified range.
How do I assign a welder to a weld?
In the welder register you keep qualifications per EN ISO 9606-1 with validity and 6-month confirmations. When assigning a welder to a weld, the system offers only those qualified for that weld (process, position, thickness, material) — so an invalid assignment cannot happen.
How do I add an NDT test and who signs it?
For a weld you set the NDT scope and methods (VT/UT/RT/PT/MT) by quality level and product standard, then assign an operator from the register (EN ISO 9712). Only an operator with the required level (≥2) signs the report. The result links to the weld and flows into the dossier.
What is the technical dossier and how do I export it?
The dossier is an audit-ready package that gathers everything — welds, WPQR, WPS, welders, NDT reports and the 3.1 material certificate (EN 10204) — into one traceable PDF. Dossier export is part of the paid subscription; individual sheets (WPS, drawing) can be printed for free.
Tools and standards
Which tools are available?
Weldmaster for welding documentation: WPQR range and check (EN ISO 15614-1), welder qualifications (EN ISO 9606-1) with tracking of the 6-month confirmations and validity, the NDT personnel register (EN ISO 9712) and the cutting calculator. You can already link welds to procedures, welders and NDT for free; the subscription adds the export of the full technical dossier.
Which standards do the calculations follow?
Ranges of qualification, coverage and requirements follow the clauses of the applicable standards — EN ISO 15614-1, 9606-1 and 9712, plus the product standards (EN 1090-2 with EXC execution classes, EN 13445, EN ISO 3834). The calculations assist; the standard and the judgement of the responsible welding coordinator (EN ISO 14731) prevail.
Do the tools work on a phone?
The quick check and the range of qualification work on a phone. The workbench for marking drawings is a dedicated desktop tool (larger screen, PDF and dragging).
How reliable are the results?
The logic follows the standards and is verified with a test battery, but it remains an aid. The user or the coordinator is responsible for the correctness of the inputs and the conformity of the final documentation.
What language are the documents in (WPS, dossier)?
Documents are single-language — Slovenian or English. You set the default language in the app and can change it per document at every print or export; a foreign customer gets a clean English WPS sheet and dossier.
Does Prokon also manage stock and material cutting?
Yes. The stock register tracks every bar with its heat number and certificate; cutting inside a project optimizes against the actual stock, deducts the material on confirmation, returns usable offcuts (≥ 100 mm) to stock with the heat number preserved, and the saw operator gets a work order with a graphical cutting layout.
Free and subscription
What is free?
Without signing in, all tools for use and printing. A free account adds one project with saving and a smaller library (up to 3 WPQRs, 3 welders and 2 NDT operators) for the connected process.
What does the subscription unlock?
Unlimited projects, unlimited libraries (WPQR/WPS, welders, NDT), the export of the connected technical dossier with traceability, and a discount on cut-on-demand.
Is there a lock-in?
No. The subscription (9.99 € per month per person) has no lock-in; you can cancel at any time and export your data. It applies to you across all your organizations.
Your data and privacy
Where is my data stored?
On servers in the EU (Supabase, Frankfurt). Each organization is logically separated at the database level — your projects and libraries are visible only to your users.
Can I export or delete my data?
Yes. You can print or export the documentation (with a subscription also as a full dossier); data or account deletion is handled on request via studio@prokon.si.
Do you sell data or use it to train AI?
No. We do not sell data and we do not use it for advertising. The AI assistant is not live yet; when it is, privacy and any transfers will be handled in line with the GDPR. Details are in the privacy policy.
Can several users work in the same organization at once?
Not yet. An organization is used by one person, and editing is locked to one device at a time (another device is offered a takeover). The workspace syncs live between your own devices. Concurrent editing by several people is in preparation.
Cut-on-demand
How does cut-on-demand work?
Upload the DXF files and receive a quote. After confirmation we run the cutting through partner production, and return the marked parts and material certificates to your project for audit traceability.
Is the service available yet?
We are setting the service up. We already accept inquiries — the quote, deadline and price are confirmed before execution.
Payments and invoices
Who pays for the subscription — the person or the company?
A subscription belongs to a person and applies across all their organizations. The payer can be a company: enter the company name, address and VAT ID at checkout and the invoice is issued to the company. An organization stays unlocked while its user holds an active subscription.
What exactly am I paying for?
For saving and the connected process: unlimited projects, your own WPQR/welder/NDT libraries, the technical dossier, stock and per-project cutting, plus a discount on cut-on-demand. The tools themselves (markup, ranges, checks, calculator) are free even without an account.
When is payment taken and when does it renew?
With the monthly plan the first month is free: you enter your card at checkout, the first charge follows after 30 days, then monthly until you cancel. The yearly plan is charged at checkout and renews every year. Lifetime access is a one-off purchase with no renewal.
How do I cancel and what happens to my data?
In your account (Account settings → Subscription → Manage subscription). Access runs to the end of the paid period. Your data is not deleted: the documentation stays visible and the organization reverts to the free plan.
Do I get an invoice?
Yes. For subscriptions the payment system issues an invoice for every payment (by e-mail and in the billing portal). Cut-on-demand is brokered — the pro-forma invoice and invoice are issued to you directly by the selected partner.
How do I pay for cut-on-demand?
Cut-on-demand is a free brokerage: you upload the files and get an indicative price range, and we find you the best partner. The binding pro-forma invoice and invoice are issued to you by them directly; you also arrange payment with them. The on-site price is indicative only. Prokon secures traceability (heat numbers + 3.1 certificates).
Do prices include VAT?
Prices are stated excluding VAT, in EUR. VAT is applied under the rules applicable to the buyer’s status and country; VAT-registered customers in other EU countries enter their VAT ID at checkout.
