Small tools we use ourselves every day. Free, no registration, they run in the browser.
A cut optimizer for linear EN/DIN profiles. Several profiles at once, with a cross-section and cutting visualization, computing the best plan with minimal waste.
The catalogue covers IPE, HEA, HEB, HEM, IPN, UPN and UPE profiles, L angles, RHS, SHS and CHS profiles, flat and round bars, and rebar. Custom entry for anything else.
Placing weld symbols on a technical drawing per ISO 2553 and exporting a PDF — free, no sign-in. Fillet, butt, edge and other welds with all the symbol extras (a-dimension, length, process, position).
When you want to link these welds into documentation — WPQR, WPS, welders, dossier — that is the job of Weldmaster, the connected program for the project.
A quick heat input calculator per EN 1011-1: Q = k·U·I·60 / (1000·v). Pick the process (MAG by default, + MIG / MMA / SAW / TIG), enter the current, voltage and travel speed.
The result in kJ/mm and kJ/cm at once, with a speed-unit toggle (cm/min ↔ mm/min). One screen on mobile — no sign-in.
What does a given WPQR cover? You enter the test piece (what was welded and tested) and the tool derives the range of qualification per EN ISO 15614-1 — what the certificate would say.
Ranges for thickness, pipe diameter, position, material group, process and filler material — all per the clauses of the standard, not an interpretation. No sign-in, no saving.
The range of qualification for welders per EN ISO 9606-1. Enter the test piece and get the ISO designation and the range table exactly per the standard — processes, filler material, thickness, positions, backing and pipe diameter.
Besides the range, a check of a specific weld (green, yellow or red) and an advisor that suggests the optimal test piece. Standard EN ISO 9606-1. No sign-in, no saving.
The tools are part of our everyday workbench. We would rather have a few clean, reliable ones than ad-chasing and waiting behind a paywall.
If you find a bug, write to us — we fix it within the week.
